If you grow Kalanchoe, you should be fully aware of what leaf and stem diseases exist and how to properly treat the flower. Now we will describe the main diseases of Kalanchoe and tell you how to cure your home flower.
Late blight
If you notice on Kalanchoe leaves brown spots are almost certainly late blight. This disease occurs due to improper ventilation or excess water in the soil (so do not flood the plant when watering).
When a plant begins to hurt, brown spots first appear on almost every leaf, and gradually the leaves may bend upward and wither.
What to do and how to save the flower? An appropriate fungicide, which can be purchased at a specialty store, will help you here.
You should also pay attention to the conditions in which the flower is kept and provide the plant with proper care (correct watering and required quantity fertilizers).
Powdery mildew
White coating on Kalanchoe leaves may be a sign of a disease called powdery mildew.
Powdery mildew on Kalanchoe - common fungal disease, which can occur due to excessive dryness of the indoor air.
Myself white coating, which can be found on Kalanchoe, at first resembles a layer of dust, but over time it thickens and becomes like flour (that’s why the white coating is called powdery).
Due to powdery mildew, the plant sheds its leaves and dies, so the disease must be treated immediately. The main danger of the disease is that it spreads quite quickly to other plants, so it is better to immediately isolate the diseased flower. Treatment is carried out using fungicides.
Gray rot
A dangerous disease due to which Kalanchoe becomes soft, its leaves begin to rot and turn into mush. Gray mold appears on the leaves, and the plant itself quickly begins to die.
The best remedy for this disease is fungicides. It is also worth thinking about how to revive Kalanchoe after the main danger has been eliminated: it is necessary to replace the soil and ensure the correct temperature conditions for your flower.
Stem rot
If you notice that the trunk of the plant has begun to darken and dry out, most likely you are faced with stem rot.
First, a small black dot appears on the stem, which then grows into a huge black spot.
Why does the trunk begin to turn black and the plant itself wither? A blackened stem can be detected when the temperature drops sharply - for example, in the winter, a flower can freeze and get sick.
How to revive a flower? Folk way, which you can use - wipe off the plaque on the stem, and then disinfect this place with potassium permanganate or ash.
Also try to normalize the temperature so that the plant receives enough heat.
Leaf ring spot
A disease from which it is impossible to save a flower. In this case, the stem also turns black, but this is accompanied by numerous round spots on the leaves of Kalanchoe. It is best to get rid of the infected plant immediately and not try to do anything.

Pests
In addition to diseases, Kalanchoe is also affected by a variety of pests. Now we will talk about the most common types of insects that can encroach on your flower garden. In addition, we will also briefly describe the main ways to deal with annoying bugs.
Mealybug
A dangerous pest that can destroy a flower in a very short time. This small insects gray in color, which can be difficult to detect.
They usually hide on the leaves and in the bud flowering plant, but in the case of Kalanchoe it is much easier to see small insects.
The main signs of the appearance of an insect are:
- falling leaves;
- waxy discharge on the stem and leaves;
- the appearance of black mold.
Shchitovka
The scale insect most often sits on the inside of the leaf or on the stem. These are fairly large brownish bugs that are easy to spot. The first sign of an attack by these pests is the rapidly drying leaves of the flower.
Ticks
Mites settle on the underside of the leaf, and their appearance is caused by dry air in the room.
The leaves of the flower quickly turn yellow, in addition, the insects themselves weave a thin web, which can be seen on the leaves. Leaves also curl and fall off.
Therefore, if no measures are taken, the plant will simply die.
Get rid of nasty bugs using insecticides. You can also treat the flower mineral oil or soap solution, and remove the pests themselves manually using napkins.
Aphid
Aphids on Kalanchoe are a common problem that can be difficult to deal with. The cause is soil oversaturated with fertilizers, which these insects love.
They settle on stems and the inside of leaves, so sometimes aphids are quite difficult to notice.
Insects suck the juices from the Kalanchoe, secreting a sticky coating that prevents the flower from breathing.
If you see that the plant is beginning to smolder, you need to take immediate action. First of all, trim off the affected leaves. Then you can treat the flower with a soap solution. If you want to quickly get rid of pests, use insecticides.

Popular Kalanchoe diseases and their treatment
One of the most dangerous pests Kalanchoe can rightly be called aphid. It develops vigorous activity in the spring.
If you don’t start helping the crop, aphids can move to nearby indoor flowers.
Even a beginner can visually determine the infestation of aphids - small insects painted black or green will be visible on the stems and leaves.
Aphids are very fond of plant sap, which poisons it by injecting poison. In addition, the foliage and stems are covered with a sticky mass. It is often possible to find aphids on young shoots or inflorescences.
But as the colony grows, it becomes clear that the culture urgently needs to be saved. After all, the plant becomes deformed, the leaves become yellow and fly off, the flowers too, and the buds simply do not bloom.
Aphids can carry more than 100 types of dangerous infections. It is best to burn the diseased parts and treat the surviving parts with an insecticidal agent. This procedure is performed once a week for a month.
A folk remedy known to many gardeners is green potassium soap. It treats the plant if 20 grams of the product are diluted in 1 liter of water. The soil should be wrapped before the procedure plastic film, then rinse the flower with the solution.
Alternatively, regular laundry soap will do.
False scale and scale insects
Scale insects are pests that belong to the group of coccids. Visually, these are insects with an oblong miniature body covered with a wax shield.
Due to the activity of pests, the plant stops developing normally, there is no flowering, the leaves turn yellow and fall off.
Scale insects, like aphids, are located on the underside of leaves. Adults usually sit motionless, and only young ones move.
To make it easier to remove insects from the surface, it is recommended to wipe the foliage with alcohol.
An infusion of garlic will also help. To prepare it, grind about 5 cloves and pour 1 glass of water over them. You need to leave for 2 hours dark place, then filter and you can spray.
Scale insects are removed from the surface with an unnecessary toothbrush.
“Treatment of indoor plants. Kalanchoe"
Why does Kalanchoe lose leaves?
Problems with leaves for your loved one indoor flower may arise for a number of reasons. One of them is a lack of lighting, as a result of which the plant will begin to stretch upward.
It can really help if you add some lighting or move the pot to a brighter place. Lack of light also leads to yellowing and drying of the lower leaves.
Stagnant air in the room can also lead to leaf fall. This is where regular ventilation comes to the rescue.
If the plants are exposed to direct sunlight or the pots are placed very close to each other, unpleasant spots may be found on the surface of the foliage.
You should arrange the containers and provide shade to the flowers. If your pet doesn't get enough nutrients, he may stop growing and start shedding leaves.
This is relevant after the end of the flowering period, and is usually treated by fertilizing or transplanting the crop into nutritious soil. An excess of nitrogen or peat in the soil will be signaled by the curling of the leaves. In this case, it is necessary to transplant the flower into another substrate.
If your Kalanchoe has become all yellow, this indicates a large amount of sunlight falling on it.
When the leaves become soft to the touch and begin to fly off, it is worth reducing watering and checking the roots for infection with root rot. They will definitely have to be treated.
The foliage still dies off in the cold season, due to its proximity to central heating. If the air is dry, it is recommended to move the flower to a room with a temperature of no more than 13 - 15 degrees. Then it will overwinter without loss of green mass.
But you need to make sure that the room is not excessively humid, otherwise you will need treatment for mold that appears in the form of brown or black spots.
Other diseases
Among other ailments of Kalanchoe, late blight rot should be mentioned. This unpleasant fungus appears in the form of brown spots at the branching point of the shoots.
As a result, culture lags behind in development. The causes of this disease are overwatering, elevated temperature, lack of regular ventilation, large amounts of nitrogen in the soil.
Late blight is treated with the use of fungicides. It is recommended to replace the soil with new soil and water the plant less often.
An excellent preventive measure would be disinfecting the soil before planting a flower, using clean tools, and constantly inspecting the crop.
When affected by gray rot, Kalanchoe becomes covered with a gray coating and weeping spots. Then the flower rots.
The disease spreads to other crops in the room - by air, by touching, by working with tools.
The appearance of gray mold is often associated with insufficient ventilation, poor lighting systems, excessively moist soil and air. The plant must be treated by treating it with a special fungicide.
If you find a powdery white coating on the surface of the leaves, then you are dealing with powdery mildew. With such a disease, the foliage will inevitably fall further. The disease develops due to elevated temperature and dry air in the room.
As in the case of gray mold, treatment is considered effective fungicidal preparations. Ring leaf spot is also dangerous for your pet. When it appears, the culture stops normal growth. Then the leaves become discolored and become unnaturally shaped.
This disease cannot be cured, so the affected areas are simply destroyed.
Stem rot is characterized by the appearance of watery black spots on the stems and foliage. It spreads quickly if there is excessive humidity in the room. You can treat the crop with insecticides. If this does not help, the diseased plant must be destroyed.
The edges of the leaves bend and their growth stops. Culture tissues become coarser. Small glassy mites settle on your flowers if the room is damp and the air temperature is elevated.
They need to be washed off with a soap solution and the plant treated with insecticides. Mealybugs, as a result of their vital activity, cover the petioles and veins of the leaves with a waxy white coating.
Treatment with insecticidal preparations or mineral oils will help.
“Saving indoor plants from diseases”
To cure Kalanchoe or get rid of pests, we recommend watching the following video. In it you will find useful recommendations and tips for treating and preventing diseases of indoor plants.

Kalanchoe diseases and measures to combat them
Almost all diseases in Kalanchoe appear due to violation of maintenance conditions. It is worth noting that this plant loves diffused lighting and moderate watering. By giving him necessary care, you will achieve and proper development, and flowering.
But if the plant begins to hurt, its leaves become covered with spots, and you find small insects on the flowers and trunk, you need to take immediate action. Let's try together to save the “green doctor” from problems.
In this article we will tell you what pests can affect Kalanchoe and how you can fight them.
Aphids on Kalanchoe
Aphids are the most dangerous enemy of Kalanchoe. It appears mainly in the spring.
If you don't take immediate action to get rid of them, aphids can also invade neighboring plants, causing harm to all your flowers.
If you find small green or black insects on the leaves and trunk of Kalanchoe, you should know that your plant is suffering from aphids.
She takes the juice from the Kalanchoe and poisons it with constant injections of her own poison.
But that’s not all - the affected leaves and stem are covered with a sticky substance, which prevents the flower from “breathing deeply.”
Most often, this insect can be found on young shoots or on inflorescences.
Signs of aphids
Frequent use of nitrogenous fertilizers stimulates the appearance of aphids. It has already been noted that aphids reproduce very quickly on fed flowers.
Aphids can enter the house on newly purchased plants or even on cut bouquets.
Therefore, it is important to keep all newly arrived flowers in the so-called quarantine zone, in other words, in another room.
At the initial stage of infection, it is quite difficult to notice any signs of aphid damage. The insects themselves are quite small and, given that aphids settle on back side leaf, then quite invisible.
A colony can be detected as it grows - due to clearly unhealthy appearance plants. It becomes dirty and deformed. The leaves begin to turn yellow and fall off, the buds no longer open, and the existing flowers fall off.
The scary thing is that aphids carry more than 100 types of viruses, and their liquid sugary secretions become a breeding ground for fungi.
How to get rid of aphids?
The most radical way is to cut off the affected areas and burn them. The remaining plant is treated with an appropriate insecticide to indoor plants. Repeat the treatment once a week for a month.
It needs to be diluted in water (20 grams of soap is needed per 1 liter) and the plant should be washed with this solution, having previously wrapped the soil in polyethylene.
If it is difficult to obtain such a drug, you can use laundry soap, it is also detrimental to aphids, although to a lesser extent.
Scale insect and false scale insect
Scale insects belong to the suborder Coccidae and are insects with an oblong two-millimeter body, which is covered on top with a waxy shield.
Females are much larger than males and have neither wings nor legs. They sit motionless, covering their eggs.
A plant affected by scale insects is covered with a peculiar coating of insects.
The leaves begin to turn yellow and fall off, the growth of Kalanchoe slows down, and flowering stops.
The condition of the plant worsens due to additional damage by sooty fungus, which multiplies in the sticky secretion secreted by scale insects.
Pests stay mainly on the underside of leaves. Only young larvae are capable of movement; adults are immobile.
To prevent this disease, the plant must be examined regularly and carefully. And at the end of winter and at the beginning of spring, make sure that the Kalanchoe is in a well-ventilated area. If the air temperature allows, spray the plant with water more often - scale insects do not like a humid environment.
Ways to combat scale insects
Insects must be collected from the leaves, and then the flower must be washed with soapy water.
To make scale insects easier to remove, they are pre-treated with alcohol.
There are no special insecticides to combat scale insects, so you can use any preparation intended for indoor plants.
You can fight pests using folk remedies - regularly (3-4 times a week) wipe the plant with a cotton swab dipped in vodka or diluted alcohol. Remove scale insects using an old toothbrush.
You can also wash the plant with garlic infusion. Grind 5-6 cloves of garlic in a mortar and add a glass of water.
Infuse the resulting mixture in a dark place for several hours, filter it and spray the plant.
Why do leaves fall on Kalanchoe?
All gardeners want Kalanchoe to always please the eye with green leaves. But it happens that the stem of a plant stretches out, and lower leaves begin to turn yellow and fall off.
This behavior indicates improper lighting - there is simply not enough sunlight for him. Sometimes this problem occurs after flowering: growth stops, the flower begins to lose leaves. All this happens when Kalanchoe is depleted.
He urgently needs a transplant or good feeding.
Leaves also die during the cold season. This is due to the proximity to central heating. Most likely, the plant is on the windowsill near the radiator, and the air around it is too dry. Move the flower to a room with a lower temperature.
The optimal temperature at this time of year is about 13-15 degrees, then the Kalanchoe will overwinter without loss of green mass.
The main thing is that when low temperature there was no excess moisture, otherwise the plant will have to be treated for mold, which manifests itself in the form of black or brown spots.
In general, when caring for Kalanchoe, it is important to trim old shoots in time, then it will delight you for a long time with its beautiful shape and abundant flowering.
Other diseases of Kalanchoe
Signs of this disease are dead brown spots in the branching areas of the Kalanchoe plant. Rot can be caused by many factors, such as overwatering or poor ventilation.
There may be excess fertilizer in the soil or the temperature may be too high. If this disease is detected, stop watering and provide the plant with a partial change of soil.
In the future, Kalanchoe must be watered with fungicides for some time.
Signs of the disease: specific spots with a white coating of fungus can be found on the leaves of the plant. Depending on the development of the disease, the leaves die.
The danger is that the fungus that causes powdery mildew is easily transmitted through the air and can infect neighboring plants. The disease develops in conditions of dry air and elevated temperatures.
Control requires regular watering (but not frequent!) and spraying with fungicides.
Accompanied by the formation of weeping gray spots on the above-ground parts of the plant. If no action is taken, the spots will grow, turning into a pasty mass, and the plant will die. The fungus that causes the disease remains in the soil for another two years.
To activate it, excess moisture, lack of lighting and poor ventilation are required. If a disease is detected, it is necessary to urgently change the conditions of detention and take care of sufficient lighting and replacement of soil. And also treat the plant systemic fungicides.
As you can see, all diseases inherent in Kalanchoe are curable. The main thing is to detect them in time and take appropriate measures.

Kalanchoe: how to properly care for a flower
→ Houseplants → Kalanchoe: how to properly care for a flower
Kalanchoe is a very valuable plant, as it combines both decorative and medicinal components. Kalanchoe comes from Madagascar, but despite its exotic nature, it feels great in the home conditions of our climate.
With proper care, Kalanchoe will definitely delight you with beautiful flowering. The buds usually have a pink tint and perfectly decorate the interior of the room.
Kalanchoe has been nicknamed the “indoor analogue of ginseng”, since it is difficult to list all the healing properties of this plant.
After all, it has a healing effect, is actively used in cosmetology and even improves the energy background of the apartment.
How to choose the right plant when buying
Before buying, you need to pay attention to the appearance of the Kalanchoe, because it depends on how strong and beautiful plant will be able to grow in the future. In order to choose a healthy plant, you need to pay attention to the following nuances:
- The stem of Kalanchoe should be smooth, without dry leaves or damage.
- It is best to buy a plant during the flowering period; the number of buds will show how healthy the Kalanchoe is.
- Considering this point, the best time to buy a plant is winter, because Kalanchoes bloom in winter and are dormant in summer.
- The foliage should not have spots.
Growing conditions
For the plant to be healthy and beautiful, it needs proper lighting, temperature, humidity and soil composition:
- Kalanchoe cannot be called a whimsical plant. You can place the plant in almost any convenient place. It is not afraid of the direct sunlight, however, it is best to choose a place for Kalanchoe where the light will be slightly diffused. From time to time it is useful to take it out into the sun in the afternoon. Too aggressive sunlight leaves burns on the leaves, and the plant begins to lag in growth. With proper lighting, Kalanchoe foliage will be framed with a brown border. If there is not enough light, the plant usually stretches out and the color of the leaves becomes dull.
- Air temperature and humidity The most suitable temperature is in the range from 23 to 28 degrees. Kalanchoe will withstand hotter temperatures, but this means frequent watering of the plant, otherwise the Kalanchoe may dry out. If we talk about low temperatures, then the critical point is a temperature below ten degrees, at which the plant can freeze and die. It is important to protect Kalanchoe from frosty winds, as the foliage of the plant is prone to frostbite. Kalanchoe does not require spraying; on the contrary, excessive moisture can be harmful to it. Therefore, it is enough to wipe the foliage with a damp cloth.
- Priming. Kalanchoe belongs to the succulent family, so you can safely buy a ready-made soil mixture in the store. However, if we look at the composition of the soil in more detail, it consists of peat with the addition of coconut fiber. The structure of the soil is loose; it should not retain water and prevent the flow of oxygen to the root system of the plant. If you make the substrate yourself, you can take different proportions of humus, turf and coarse sand. It is important to disinfect the soil before planting the plant in order to avoid various infections of Kalanchoe.
Watering and fertilizing
Since Kalanchoe is a succulent, overwatering can cause great harm to the plant.
Watering should be done as follows: completely spill the soil and drain the remainder through the holes in the pot to prevent stagnation of water.
IN winter time A couple of waterings per week is enough for the plant; in extreme heat, the frequency should be increased.
Excessive watering of a plant can be identified by the following signs:
- Droopy foliage of dull color.
- Appearance dark spots with a yellow border.
- The soil remains moist and does not dry out.
How to save a plant:
- It is necessary to remove the plant from the planting container and check root system. If it is not damaged by rotting, then the Kalanchoe does not need to be replanted.
- Blot the roots of the plant with a napkin.
- Place the Kalanchoe in a warm and dry place (but not near heaters).
- After the plant has dried, it can be returned to the planting container, updating the drainage if it is not good enough.
In case of damage to the root system, all rotten areas must be cut off and the cut areas treated with an antiseptic solution or ash. Next, the plant needs to be dried and you can begin replanting.
Kalanchoe does not require frequent feeding; it is enough to choose a fertilizer composition in the store that is intended for succulents and use it according to the instructions.
You should not feed Kalanchoe in winter, as this can harm the plant.
How to transplant correctly
Basic rules for transplanting Kalanchoe:
- Kalanchoe grows quite intensively, so it may require annual replanting.
- Each time the landing capacity is increased by at least three centimeters in volume.
- You should not replant the plant during the flowering period, as there is a risk that the buds will fall off and adaptation will be extremely difficult.
- Having previously moistened the soil well, the plant is taken out of the planting container along with clods of old soil, and then thoroughly shaken off.
- Before transplanting, always inspect the root system for rotting and remove the affected areas.
- The new pot is washed thoroughly hot water and rinse with a solution of potassium permanganate.
- Next, a layer of drainage (from 2 cm thick) is laid on the bottom of the planting container and sprinkled with prepared and disinfected soil up to half the pot.
- The plant is placed vertically and sprinkled with the remaining soil, subsequently compacted.
- You can add fertilizer to the soil for better adaptation of the plant.
- Kalanchoe is spilled with water, waiting until the excess moisture drains out of the holes in the planting container.
How to prune correctly
Pruning is very useful procedure for Kalanchoe. Thanks to timely pruning, the crown becomes richer and a lot of new shoots appear. Kalanchoe pruning is carried out after flowering. Dried inflorescences are cut off to the very base, after which the Kalanchoe produces new shoots.
In addition, you can pinch the Kalanchoe; this manipulation will allow you to form a crown and give it a neat appearance.
How to properly prune so that the Kalanchoe blooms again:
- First, the plant must be placed in partial shade; light should reach the plant no more than six hours a day.
- After this, it is necessary to prune the dried inflorescences; new buds should no longer form.
- Watering is reduced to once every two weeks.
- The plant is kept in a cool place, the temperature should not be more than 20 degrees.
- Before in winter care is returned to normal.
After these simple procedures, the Kalanchoe begins to bloom soon.
Problems due to improper care
The consequences of improper care can negatively affect Kalanchoe, so it is very important to maintain a comfortable living environment and monitor the condition of the plant.
There are several main points that owners of this plant may encounter:
- If the Kalanchoe becomes elongated and the lower leaves wither, then it does not have enough sunlight.
- If Kalanchoe sheds its leaves, this may be the reason for rare ventilation of the room.
- Spots on Kalanchoe foliage can appear due to sunburn or excessive crowding of plants.
- If Kalanchoe stops growing and drops its leaves, this may indicate a lack of nutrients in the ground.
- Curled leaves of a plant may indicate too much peat in the soil.
- If Kalanchoe foliage becomes soft and falls off, this is due to too frequent watering or rotting of the root system.
- If the foliage of the plant dries out, then most likely the frequency of watering should be increased.
Main diseases of Kalanchoe
The most common diseases that you may encounter when growing Kalanchoe are:
- Gray mold damage occurs due to excess moisture and improper lighting conditions. The foliage becomes covered with spots and a gray coating. The disease spreads very actively to nearby plants. Treatment occurs by treating the plant with a fungicide.
- Powdery mildew is manifested by the formation of a whitish coating and loss of leaves. The disease occurs due to excessively dry air or heat. Treatment is carried out by treating the plant with a fungicide.
- Rot appears as black and wet spots on the plant. It usually occurs due to high humidity and is treated with an insecticide. But if treatment does not help Kalanchoe, then the plant should be disposed of.
- Ring spotting, which appears as characteristic circles on the foliage of the plant. The leaves become rough and lose their shape. This disease cannot be cured, so it is necessary to dispose of the plant as soon as possible.
Pests of Kalanchoe
The main pests of Kalanchoe that you may encounter:
- Multi-clawed mite. Its presence is manifested by brown crusts on the foliage of Kalanchoe, which stops growing and begins to curl inward. A mite is a white or transparent insect that lives directly on the plant. To combat the pest, wash with a soap solution and subsequent treatment with an insecticide.
- Aphid. When infested by aphids, the foliage becomes yellow and deformed with a sticky coating. Fight aphids with a soap solution and a suitable insecticide. Aphids very actively spread to neighboring plants, so it is necessary to carefully monitor the condition of Kalanchoe.
- Mealybug. The veins of Kalanchoe leaves are covered with a whitish coating. To combat the mealybug, it is necessary to remove all affected leaves, and then treat the plant with an insecticide.
- Shield. Kalanchoe foliage dries and falls off, the stem becomes covered with a sticky coating, and the plant stops growing. Pest control is carried out by manual collection pests and washing the plant. The dense shell of the scale insect protects it from most chemicals, so wiping the foliage with a swab moistened with alcohol is a good idea. However, you should be careful not to burn the plant.
Kalanchoe - pretty unpretentious plant. If you know the main points of proper care and maintain a comfortable living environment, then the Kalanchoe will become a real decoration of the house and will delight the owner with beautiful flowering.
White plaque on Kalanchoe: what is it and how to fight it
If a white coating appears on the Kalanchoe, it means that the plant has been affected by the fungal disease “powdery mildew”. It is recommended to treat the flower immediately. The disease can destroy Kalanchoe.
White plaque on Kalanchoe: what to do
Source: Depositphotos
White plaque indicates the disease "powdery mildew"
Spores of pathogenic fungi are found in the soil and appear only if the rules of plant care are not followed. Fungal disease occurs:
- in case of violation temperature regime. Cool air and humidity are favorable for the development of spores;
- excess nitrogen in the soil;
- irregular watering. The top layer of soil should dry out slightly before irrigation occurs. If it dries out or, conversely, does not have time to dry before the next moistening, the fungus becomes active.
The soil in the pot becomes infected by air and through watering if the water is contaminated. The fungus is also transmitted through human hands. Once you touch one plant, do not touch another unless you wash your hands thoroughly.
Fighting powdery mildew
To combat white plaque, complex treatment is used. First of all, it is organized proper care for Kalanchoe. It includes watering, no spraying, removing old foliage and sunbathing for Kalanchoe. No fertilizers are applied to the soil, nitrogen fertilizing is excluded.
To cure Kalanchoe and get rid of spores, you need:
- remove the affected parts of the flower;
- change top layer soil in a pot;
- spray the flower chemical preparation- a fungicide or a prepared folk remedy, for example, mustard solution. Or dip the plant in a bowl of solution. The medicinal liquid should generously moisten the surface of the above-ground part of the plant.
After treating the Kalanchoe, proceed to treat the soil, walls of the pot, and tray with the same product.
It is worth noting that folk remedies should be used for preventive purposes and in the early stages of infection. If a large area of the flower is affected, commercial chemicals are used.
Plaque on a flower is a sign of a serious disease. Start treatment as soon as possible to save the flower.
Kalanchoe grows in tropical areas of Africa, Australia and Asia. Blooms in white, yellow, red or purple flowers, collected in umbrella-like inflorescences.
Types of Kalanchoe:
- Degremona. Decorative foliage plant. The leaves are triangular, up to 10 cm long. The stem is straight. Cuttings with roots - “babies” - are formed on each leaf. After ripening, they tear off the leaf, fall into the ground and germinate. Dergemona is appreciated for healing properties. It grows on the shores of seas, rivers and rocky slopes. The leaves are thick, gray-green in color.
- Cirrus. Height is about a meter. The stem is straight and woody. The root system is branched. Large tubular flowers of white and pink color are collected in a paniculate inflorescence. The length of the flowers is up to 5 cm. The leaves are drop-shaped, juicy, green. “Children” form along the edges of the sheet.
Kalanchoe is easy to grow at home.
Lighting
Period natural light for Kalanchoe – 12 hours. Place the pot with the plant in the spring-autumn period on the east or southwest side. In winter, place it on a south window.
If there is not enough natural light, extend the daylight period artificial methods. In summer, maintain the air temperature at 23-26˚C. In winter – 12-16˚С.
From spring to autumn you can keep Kalanchoe on outdoors.
Watering
Avoid frequent watering. Excess moisture in the soil leads to rotting of the root system. Water sparingly to prevent water from flowing out of the drainage hole. The water should be soft, warm and settled.
In winter, water 3-4 days after the soil dries. You can water through the tray.
Kalanchoe does not need spraying. But if the air temperature is high in summer, spraying will be beneficial. High content moisture in the leaves ensures resistance to lack of watering for 2-3 days.
Fertilizers
Feed the plant in summer and spring during budding. Fertilize it with minerals every week. Organic - every 2 weeks.
To prepare your own fertilizer, take chicken or cow droppings and dilute it with water in a ratio of 1:10. Onion peels or eggshells are suitable for feeding.
Recipe No. 1
- Mix 50 gr. onion peels in 2 liters. water and boil.
- Let stand for 2 hours.
- Water once every 2 weeks.
Recipe No. 2
- Finely crush the eggshells and pour in 1 liter. water.
- Let it brew for a week.
- Water as needed.
If you don't like the smell eggshells, water the plant outdoors. This way the smell will quickly evaporate.
Reproduction
This can be done in three ways.
Cutting or leaf
- At the beginning of summer, cut off a healthy, strong cutting.
- Remove the lower leaves.
- Plant the cutting in the ground.
- Pour and cover with a jar.
- Spray periodically.
- 2 weeks after the root system appears, transplant the plant into a pot with substrate.
Transfer
Kalanchoe does not need frequent transplants. Replant the plant when the roots have completely filled the market. Take the new one 2-3 cm wider than the previous one. Water the plant thoroughly before replanting.
- Carefully remove the Kalanchoe. Avoid damaging the stems and leaves: they are very fragile.
- IN new pot fill the drainage with crushed bricks, expanded clay or pebbles.
- Sprinkle some soil and place the plant there.
- Sprinkle the rest of the soil on top, tamping lightly with your fingers. For soil, take equal amounts of turf, forest soil and sand.
- Add some humus.
Transplant Kalanchoe in the spring during the waxing moon.
Diseases of Kalanchoe
All diseases of Kalanchoe appear as a result of its improper maintenance.
Late blight rot
Spots appear on the leaves brown. This indicates poor ventilation and frequent watering, high temperature indoors or overfeeding with fertilizers.
Stop wetting and change some of the soil. Water the plant with a fungicidal solution for a month.
Powdery mildew
White spots are visible on the leaves. Some leaves are dying. Powdery mildew can spread to other plants.
The disease appears due to dry air and elevated temperatures. Increase the frequency of watering and humidify the air. Treat the plant with a fungicidal solution.
Gray rot
Gray putrid spots appear on the stems and leaves, which quickly grow and the Kalanchoe dies. Fungal spores live in the soil for 2 years, so after destroying the plant, throw away the soil or heat treat it.
The cause is excess moisture or insufficient lighting.
Fungicides, such as Teldor or Topaz, will help get rid of gray rot.
The stem stretches, the lower leaves fall off
The cause may be improper lighting or lean soil. Move the pot to a bright window and apply fertilizer.
Why do Kalanchoe leaves turn yellow? What to do? This query is often entered into search engines by people who are too actively caring for their indoor flowers. Let's look at why this happens.
Improper watering
Most gardeners do not realize that Kalanchoe is a succulent. Water is poured with a generous hand, from the heart and often. They don’t even allow the soil in the pot to dry thoroughly. But the plant is quite capable of doing without watering enough for a long time. And overwatering leads to severe rotting of the roots. And while it is very easy to save a Kalanchoe that has withered due to drought, one that has turned yellow from overwatering is almost never restored.
Signs. The leaves turn yellow throughout the plant, soft, watery. The Kalanchoe itself looks depressed; often the shoots bend under the weight of water inside the leaf blades.
What to do. Urgent rescue! Simply stopping watering, as some sources recommend, will do nothing. The root system has already begun to rot. This process must be stopped immediately, otherwise the plant will die.
To do this, remove the Kalanchoe from the pot, then thoroughly wash the roots under running warm water. Now you need to carefully cut off everything rotten, bad-smelling and dark in color. The sections are sprinkled with crushed activated carbon, leave to dry in the open air for at least an hour.
After this, the Kalanchoe is transplanted into another soil and a new pot. The old one may contain many pathogenic bacteria.
In the future, the moderation of watering is strictly monitored. Recommended scheme: the top layer of soil in the pot has dried, plus another 5 days. By the way, they are not particularly zealous. The soil is only slightly moistened. There is no need to wait for water to flow out of the drainage holes. Kalanchoe doesn't like this. Otherwise, the root system, like a pump, will absorb absolutely all the moisture. And the unknowing owners will start watering the plant again when they see dry soil in the pot. The circle will close and the leaves will begin to turn yellow again.
Incorrect lighting
Signs of lack of light. The leaves turn yellow and become smaller. The shoots become thin and long, like matches.
What to do. Kalanchoe loves bright light. But no more than 10 hours a day. Therefore, there are only 2 outputs:
- Artificially create short daylight hours by covering the Kalanchoe with light-proof material.
- Choose a place of detention where the duration of lighting will be normal. For example, the eastern window sill.
By the way, if the Kalanchoe has already stretched out and turned yellow, then it will not be possible to save the shoots. They will no longer become a lush compact bush. They will have to be cut off. Just don't throw it away. Such shoots take root well, so why not get a few new plants? These can then be easily formed into a beautiful crown with proper care.
Dry air
The second most common cause of yellowing of Kalanchoe leaves, especially during the heating season. Rarely does anyone think about how hot heating radiators affect a plant.
Signs. The tips of the leaves throughout the plant turn yellow and then begin to dry out entirely.
What to do. Humidify the air around the Kalanchoe as often as possible. You can do this in several ways:
If you do not have the opportunity to provide Kalanchoe with normal moist air, then it is better to artificially put it into a state of rest. Place in a cool place (+14-16°C), reduce watering. The plant can remain in this position for no more than 2 months, but then you will have to come up with something to increase the humidity. Otherwise, the tips of the leaves will turn yellow.
High temperature
Signs. The leaves turn yellow throughout the plant, look cooked, wrinkled, but not dry. The plant overall looks healthy.
What to do. Stop frying Kalanchoe. It loves bright light, so many gardeners place it on a south or west window. This is quite acceptable, but only in recent years summer middle zone brings incredible surprises. In the sun, the thermometer creeps much higher than +40°C. As a result, the plant is simply fried.
It is imperative to shade the Kalanchoe in the hottest sun. This can be done with white paper or thick light cloth. As a result, the plant will receive enough light, but will not get sunburned. Or better yet, move the pot behind the curtain. For example, on a table or bedside table near the window. Then you won’t have to fence the shading every day.
Natural wilting
Signs. The leaves sometimes turn yellow at the bottom of the stem, gradually dry out and fall off. The plant looks vigorous, grows and blooms well.
What to do. Don't change anything! Your pet is happy with absolutely everything. And the loss of a certain number of lower leaves is a normal natural aging process. You should not interfere with the usual microclimate. Kalanchoe feels great.
Wrong fertilizer
An excess of nutrients is just as destructive as a deficiency. Immediately after transplantation, some comrades begin to zealously pour handfuls of fertilizer into the pot. What about Kalanchoe? The root system absorbs everything without complaint. But the leaves refuse to accept such gluttony.
Signs. The leaf blades first turn yellow, then turn brown. A red border and brown weeping spots may appear. The plant looks unhealthy and does not bloom. A large number of loose shoots appear, and the tops may begin to rot.
What to do. Stop eating yourself and stop stuffing an innocent flower. This is a succulent, it is used to living in very harsh conditions. And you give him fertilizer!
Normally, you need to reduce the dose of microelements recommended by the manufacturer by 2 times. Then all this goodness will be useful. Too much is always harmful. Have you ever seen fat people full of health? There are no such things. So why should it be any different with Kalanchoe? Always think before you pour mineral water into your irrigation water.
Advice. To avoid mistakes, use long-lasting fertilizers. Simply place the tablet or granule in the pot. Kalanchoe itself will take as much food as it needs during the next watering.
Signs. Leaf blades change pigmentation throughout the plant, sticky spots and small dots appear. Then they grow.
What to do. Open your eyes. After all, it is very difficult not to notice uninvited guests on the leaves of Kalanchoe. Insects are very clearly visible to the naked eye, especially on the underside of the leaves.
Immediately treat the victim with any systemic insecticide. Just be sure to look for the phrase “approved for indoor plants” on the packaging. And strictly follow the dosage.
It is advisable to quarantine the Kalanchoe for a while so that other flowers do not become infected. If necessary, the treatment is repeated again after about 7-10 days.
Excessive watering or too cold air often leads to various diseases. As a rule, owners realize this too late.
Signs. The leaves turn yellow very quickly, then become covered with a bluish coating. Or whitish fluff. The plant withers and then dies.
What to do. Of course, you can try to save the Kalanchoe by spraying it with a fungicide. But even if it recovers, it will look very unpresentable. What beauty is there in a long bald stem with a bunch of crooked, misshapen leaves at the top? Still not a palm tree.
There is only one way out of this situation. You will have to cut as many healthy cuttings as possible to try to root them and grow a new Kalanchoe. As a rule, there are no problems with this; the shoots very quickly gain strength, build up the root system and begin to grow.
And there is no need to grieve over the loss. In any situation you need to be able to see your advantages. But you will have many young healthy plants instead of one sick and shabby poor fellow.
Now you know why Kalanchoe leaves turn yellow. What to do? - also aware. Therefore, you can provide your pet with decent living conditions at home and without yellowing. And he will thank you with lush green foliage and fabulous flowering.

Why did the Schefflera leaves become sticky? How to care for her?
This is a scale insect or a false scale insect. If affected by scale insects, treat with Actellik. It is necessary to dilute the ampoule in 1 liter of water and treat it during the period when the pest appears. Solution consumption up to 2 liters per 10 sq.m. No more than 4 treatments. Waiting period 3 days..
It's either a scale insect or an aphid...mine had a false scale insect. I just washed it off slowly with soapy water and that was it. I already have it as a tree. It was not possible to wash everything right away. Gradually. good luck to you)
I read that such a disease needs to be fought by washing off the aphids (scale insects). Once a week - shower under pressure, but at the same time cover the ground with cellophane. Periodically, the plant must be washed with a soapy solution of laundry soap, and after an hour and a half, be sure to wash it off, but do this in the absence of sun. Good luck! Also, do not pour water into the plant, and use warm and softened water; between treatments, spray the plant with warm water from a spray bottle. And remember that water quality plays a very important role in the life of plants and other living organisms!
The first sign is a shiny sticky discharge that looks like a splash of syrup.

Kalanchoe - flower of life
Kalanchoe is not only decorative, but also medicinal plant. The birthplace of this beautiful flower is Madagascar. This plant itself is unpretentious, but you just need to follow some rules for its maintenance. Kalanchoe, like cacti, belongs to the genus of succulents; only a few species grow in indoor floriculture, although in wildlife there are almost 200 species. For more than a century, this plant has been helping people restore lost health.
Varieties and types of Kalanchoe
Since there are many varieties found in the wild, we will describe only those that are found in our garden centers, and, therefore, they grow in our houses and apartments.
All varieties have beautiful bloom and healing properties.
Kalanchoe Blossfeld
Planting, care and propagation
Like any plant, it has its own secrets. It has taken root well at home. Just growing it, you need to follow certain rules, here are some of them.
How to properly create a watering regime
This tropical plant does not respond well to waterlogging of the soil. When the ground is constantly wet, the roots will begin to rot. Even when the plant blooms, watering is not increased, but watered occasionally and little by little.
IN summer period The plant is watered with cool water that has been standing for a day to get rid of chlorine. If the water is very hard, then the water must be softened by boiling. To do this, boil half of the water and let it settle. After which it is mixed with settled water, as a result the hardness decreases.
When watering, you should also avoid getting water on the leaves and trunk. If they come into contact with them, rotting may begin. If the plant overwaters, it must be carefully removed from the pot and wrapped in a lump of soil with disposable paper towels, which will absorb excess water. In hot weather, the approximate frequency of moisturizing is once every four days. Since the plant has a large supply of water in its leaf blades, it does not face a lack of water. Overwatering is more dangerous for him.
In winter, especially if the room is cool, the plant is watered much less often. Need to water warm water about once a week. If overwatering occurs in winter, the plant is likely to die. After watering cold water the plant may become sick and die.
Lighting
Since the homeland of this plant is South Africa then he loves it very much solar lighting. You can safely leave it on a sunny windowsill in the summer until lunchtime. In the afternoon, if there is no natural shadow, then it must be created. Otherwise, the succulent leaves may burn in the afternoon sun. Burns that appear on the leaves do not heal and remain until the end of the leaf's life. In winter, the sun is safe for the plant and there is no need to move it into the shade.
Temperature
This plant prefers moderate temperatures from 16 degrees 20 degrees Celsius. But even if the temperature drops to 5 degrees Celsius, it will not cause damage to the flower. The most interesting thing is that this flower cannot tolerate temperatures above 30 degrees, and begins to suffer from various diseases.
Humidity
No flower required high humidity air and therefore does not need daily spraying. If you constantly expose it to high humidity, the leaves will accumulate an excess of water and begin to crack. And already the fungus can get into the damaged leaves, and the leaf begins to rot. So the dry air is in heating season he is absolutely not afraid.
Top dressing
There is almost no need to feed, since the plant does not like feeding and reacts poorly to it. But if a lack of grip still begins minerals, then you need to start fertilizing with fertilizer for cacti, since there is a low nitrogen content. In winter, fertilizing is strictly prohibited; the flower will not survive this. Best time for fertilizing, this is the beginning of May and when watering with fertilizer for cacti, the dose should still be halved.
Transplanting a plant
It is good to replant a plant using transfer; this is a method in which the old soil is not shaken off the roots, but is simply carefully transferred from one pot to a slightly larger one. You should not water immediately after transplanting.
The first watering is carried out the next day after possible wounds on the roots of the plant have healed. At good conditions The flower is accepted within a week. If for some reason the transplant is carried out in winter, then the room must be warm.
Reproduction of Kalanchoe
The plant, like the money tree, propagates very easily - by cuttings, children or seed propagation. It is very interesting when fallen leaves in the same pot take root in the ground and a small young bush forms at the feet of an adult plant.
To propagate using seeds, they are planted without burying them in the ground and covered with dark glass. As soon as the first leaves appear, they are transplanted into individual pots with a diameter of no more than 7 cm. During the period of growth of children, they are sometimes fed with fertilizer for cacti.
Kalanchoe flowering
Flowering occurs once a year, at the end of winter and lasts depending on the plant variety, sometimes until the end of May.
The secret to flowering at home is that certain conditions must be met. The plant needs to be provided with two months of rest (a cool place and scanty watering) and 8 hours of daylight. To do this, it is either covered with a cap or taken out into a room deprived of light. After these manipulations, it is placed in a brighter place, and after a while it throws out bouquets of flowers at the ends of its branches.
Pests and diseases of Kalanchoe
Diseases arise for various reasons.
Useful properties of the plant
Using Kalanchoe juice, decoctions are prepared that are used for inflammation or irritation of the skin. In addition, the juice is rich in vitamins, so it is taken for vitamin deficiencies, as well as for physical or mental fatigue.
But pure juice cannot be used; it is highly concentrated and causes a burning sensation when used. Various ointments and decoctions are prepared from the squeezed juice.
Ointment for skin lesions
Juice is obtained from juicy young leaf blades, 30 ml. You need to add 50 grams of this juice. lanolin and petroleum jelly. The extracted mass is thoroughly kneaded and stored in the refrigerator. The prepared ointment can be used to treat any skin damage from irritation to frostbite.
Alcohol tincture for the treatment of varicose veins
This alcohol tincture increases blood flow through the veins. To get rid of the blue network of veins, you need to rub your legs with the tincture, starting from the feet and rising to a third of the thigh. After 15 minutes the pain goes away, but in order to completely cure your legs you need to undergo a course of treatment for 4 months. Rub those places where the blue network of veins is clearly visible.
Grind the juicy leaves and add 2 tbsp. add 500 gr. vodka or alcohol. Leave for 10 days in a dark place, stirring the contents daily. After cooking, store in the refrigerator.
For any diseases of the oral cavity (sore throat, stomatitis)
You can squeeze the juice yourself, or you can buy it at the pharmacy. But we must remember that pure juice causes a strong burning sensation, so before drinking it should be diluted with boiled water 1:2. Rinse your mouth four times a day.
Treatment of helminthiasis
Cracked nipples
Often, while feeding a child, painful cracks appear on the nipples; in order for them to go away, you need to put 3-4 drops on the crack every day and the cracks will heal. Kalanchoe is also used in folk recipes in the treatment of gynecology.
Contraindications
It is believed that this plant has no contraindications for the treatment of various diseases. And official medicine emphasizes that this plant is not toxic. But since the plant juice itself is rarely used, it usually comes with some other components, this must be taken into account. Therefore, this green doctor also has contraindications. And doctors believe that there are a number of diseases for which this drug cannot be used.
Firstly, the use of this plant must be agreed upon with the attending physician. Since there is an allergic reaction to drugs made from this plant. It should also not be taken during pregnancy and lactation. Low blood pressure is also not conducive to the use of extracts from the plant. Patients with tumors and liver disease, diabetes and rheumatism should also not take medications with this plant.
Children should also not be given undiluted Kalanchoe juice, as it severely irritates the mucous membranes even in adults.
To check whether there is an allergic reaction, you need to drop five or six drops of juice on the inner bend of your arm. Wait 10 minutes and if the allergic reaction does not make itself felt, then treatment can begin.
Collection and storage of Kalanchoe
Before picking the leaves, it is necessary for the flower to accumulate nutrients. Therefore, you need to not water the plant for a week, and then carefully cut it off. required quantity leaves from which the juice will be made. Then the leaves need to be washed and chopped. Infuse in a dark place for 5 days. After using gauze, squeeze out the juice and add medical alcohol in a ratio of 1 to 5, then keep the resulting tincture in the refrigerator. With proper storage, the shelf life of raw materials remains for a year.
Kalanchoe is considered not a picky flower, and with proper care it will not only delight you with its blooms, but also heal the whole family. So this is a wonderful reason to start growing this beautiful flower on your windowsill.

Why do houseplants have sticky leaves?
While admiring and caring for house flowers, we sometimes notice that our indoor plants have no visible reasons suddenly the leaves became sticky. Alarm bell anxiety makes us look for a solution to this riddle.
Sources of the problem
A healthy flower always looks natural and luxurious. Any deterioration in appearance should always be cause for concern. Why do the leaves of indoor plants sometimes become sticky? Why have our gentle beauties lost their attractiveness? Is this just an external drawback or is this phenomenon really dangerous for our green friends?
Unfortunately, this symptom indicates that our pets have become a refuge for small, sometimes unnoticeable insects. Sticky coating on the leaves of indoor plants is nothing more than an accumulation of waste products of pests. Who could have left him?
We will not be able to cope with other pests without special chemical means of protection. Most of the means used for protection are suitable to combat them. garden plants. But, taking into account the specifics, you should choose only those that are approved for use indoors or in a greenhouse. It is advisable to give preference to drugs that have a systemic effect.
Advantages of systemic drugs:
Very often, a single treatment of a plant may not be enough. The fact is that while acting on adult pests or their larvae, the drugs do not have a noticeable effect on already laid eggs. After a couple of weeks, new larvae may emerge from them, so it is advisable to repeat the treatment after about 2-4 weeks.
Prevention is the best answer!
When purchasing a new pet, carefully inspect it so that there is not the slightest sign of pests. After new flower appears in the house, you should not immediately place it next to other plants. Just in case, let him undergo “quarantine” while being away from them. If everything went well, you can place it closer to the “old-timers”, creating new interesting compositions.
After the diseased plant recovers, it must be replanted. When replanting plants, use new flowerpots for them. If you want to transplant a flower into an old favorite pot, you must first boil it with a soap solution.
From time to time, carefully inspect your home flowers, wipe their leaves, and do not allow pests to settle on them. For some plants, it is allowed to have a warm shower from time to time.
The more attentive you are to the flowers, the more magnificently they will grow. living decoration your home!
Why does Kalanchoe not bloom, but only produce foliage and the leaves turn yellow?
Aphid, mealybug, scale insects are the main pests of Kalanchoe. The insects feed on succulent leaves by piercing their tentacles and drawing out cell sap like a hypodermic needle. Let's consider why a plant may not bloom or produce foliage, but turn yellow and darken.
Kalanchoe diseases: treatment at home
Late blight rot
Poor soil breathability, associated with waterlogging, leads to rotting of the roots. Soil pathogens such as late blight exacerbate the problem.
Late blight is dangerous for many plants, manifesting itself everywhere equally
Symptoms of late blight fungal infection:
- As the disease progresses, a moldy smell appears.
What to do: prevents the development of late blight rot by replanting Kalanchoe in a permeable, sterile environment. This is a soil containing peat moss and perlite. ( 60:40 or 50:50).
If using an old pot, disinfect it in a 10% bleach solution (1 part bleach - 9 parts water). Phytophthora does not survive in dry tissue, but forms dormant spores that survive for long periods without a host plant.
When soil moisture and temperature conditions are favorable, its development increases and can reach invasive levels.
Should not be left in the tray standing water which flows out through the drainage holes. The roots are able to reabsorb it. Treating the soil with a fungicide (thiophanate methyl) helps control the fungus.
Methyl thiophanate can help with soil contamination with fungus
However, chemicals are effective only if the damage to the root system is not too extensive.
Thanks to this method, the flower less susceptible to infection late blight. Significant suppression of symptoms is observed when treated with salicylic acid and silicon or chitosan.
We have already described the negative impact of the disease on specific varieties of Kalanchoe. For example, how late blight manifests itself and is treated in Kalanchoe kalandiva.
Gray rot
Causative agent of gray mold– pathogenic (necrotrophic) fungus Botrytis gray. The main factors for its appearance are high level humidity and cold temperature environment.
Once the disease is detected, it is urgently necessary change conditions of detention Kalanchoe. Remove infected areas. Clean the plant with systemic fungicides. Take care of good lighting. You may need to change the soil.
Powdery mildew
Fungal disease that affects wide range plants, including Kalanchoe. It is easily recognizable because the symptoms are very peculiar:
- small chlorotic spots on leaves;
- as it grows, the fungal mycelium covers increasingly larger parts of the plant, appearing as a dusty white or grayish-silver web;
- black or brown spots(fungus fruiting body) on the mycelial surface;
- growth slows down due to impaired photosynthesis, buds do not ripen;
- curling and falling off of the integument (an atypical brownish symptom resembling scab may occur).
- the plant is polluted and deformed;
- leaves turn yellow;
- the buds don't bloom, drops real flowers;
- the affected parts and the stem are covered with sticky matter.
- pyrethrum;
- natural fatty acids;
- rapeseed oil.
- Using a cotton swab well soaked in alcohol, remove insects from the flower.
- Spray on the leaves of an infected flower organic insecticidal soap or a solution of soapy water (at the rate of 1 teaspoon of baby liquid soap per 1 liter of water).
- If the plant is young, it is easier to wash it under running water or in the shower with soapy water.
Powdery mildew is a fungus that attacks any plants: indoors and outdoors.
Conditions favorable to the development of the disease:
moderate temperatures with high humidity
Treat with fungicides (benomyl, fenarimol), sulfur-based, neem oil, potassium bicarbonate. The selected product is applied both to the stem and to the axils of the leaves.
A product that has proven its effectiveness and is even comparable to some fungicides - milk diluted in water(1 part milk to 10 parts water). It is good to use at the first sign of infection or as a preventative measure.
The mechanism of action is ferroglobulin. This whey protein, when exposed to sunlight, produces oxygen radicals, upon contact with which the fungus dies.
Pests: what to do
Aphids: how to stop blooming and dropping flowers
On initial stage infection, any signs of aphids are difficult to detect. The insects are so tiny and located on the back of the leaf that go unnoticed.
The danger of aphids is that they quickly move to neighboring plants.
The colony is discovered during reproduction. It has been noticed that aphids quickly reproduce on full-fledged Kalanchoe flowers.
The pest drinks the cell sap and constantly contaminates it with poisonous injections.
Symptoms:
The scary thing is that aphids are carriers of more than 100 types of viruses. The insect needs to consume huge amounts of juice because the concentration of sugar is too high relative to the concentration of amino acids.
The pest deposits sugar in the form of a sticky secretion on the leaves and stems of plants, which attracts ants and serves as a nutrient solution for fungi. This “nectar” clogs the respiratory pores (stomata), interfering with the plant's ability produce its own nutrients.
To get rid of aphids, Kalanchoe is treated with an appropriate insecticide. Treatment is repeated once a week for a month.
Recommended green soap solution(20 g of soap per 1 liter), which is used to wash the plant, having previously covered the soil with polyethylene. An alternative is to use a solution with laundry soap: it also harms aphids, but to a lesser extent.
But the first thing to do is:
Aphids are attracted to Vaseline, which can be rubbed at the base and thus control the population.
Tiny bugs that resemble brown or orange discs or blobs can be found on the underside of the leaves near the veins, on the stem, at the junction of the leaf and the stem.
This "nectar" attracts sooty mold growing on leaves. In general, the process is not that fast, often taking many weeks before you notice that the plant has become a target for the pest.
How to save: Products containing the following chemical ingredients are effective for control:
For prevention Check regularly for signs of scale infestation. The soil should be free of weeds, which often contain pests. Ants running up and down and “milking” the sticky secretion is an important signal.
Mealybug
Tiny, oval shape, with powdery wax coating mealybugs look like cotton specks, which are often mistaken for mold. They move slowly, but when they find it for themselves suitable place, then become motionless and form clusters.
When attached to a plant, they secrete a sticky substance that they use for protection, while absorb plant juice.
Mealybugs are as easily identified as scale insects
The damage caused by mealybugs is not immediately apparent, but it is destructive over time. As with any pests of indoor plants, treatment must begin immediately as soon as the problem is discovered.
Not recommended use synthetic pesticides, since mealybugs are resistant to most chemicals. In addition, it develops resistance to pesticides that are used on a regular basis.
It is best to use safe methods:
In this case, you will also need a product to get rid of ants. This is very important because ants protect these pests and move their waste from one plant to another.
Diagnosis of symptoms: questions and answers
Does not bloom, only produces foliage
The reason is that Kalanchoe does not bloom, despite the fact that the leaves are succulent and healthy, maybe in excess of fertilizers. Kalanchoe is a short-day plant and blooms depending on how long it is in the dark.
If it is exposed to sunlight every day for more than 12 hours, it may not bloom.
Why do the leaves curl?
Kalanchoe is sensitive to thrips, cyclamen mites and leaf rollers, which cause curling. If this is the problem, then treatment with an insecticide or miticide will be needed.
The fact is that Kalanchoe is rich in flavonoids, which are considered protective against UV.
Ultraviolet radiation negatively affects the health of the flower, causing painful symptoms.
Appearance of black spots
Most likely, it is caused by a fungal disease. This means that Kalanchoe is suffering from low temperature and excess humidity.
In addition to being unsightly, black spots can cause damage at the cellular level, resulting in leaf drop (defoliation).
The appearance of black spots may be a sign of a secondary complication, for example, after a mealybug infestation.
Brown spots on leaves
Formed as a result of dropsy (edema) or fungal infection. The best way keep the leaves healthy, avoid wetting them. Although succulent leaves are thick, fleshy, and filled with sap, it is does not mean that Kalanchoe needs to be watered more often than other plants.
On the contrary, the soil should dry out between waterings. Kalanchoe is sensitive to excess fertilizer and usually needs rare and diluted supplements (light fertilizer once a year).
If there is an excess of salts contained in the fertilizer, they accumulate in the soil and can burn the roots. And as the salt solution moves upward, it affects the leaves, causing formation of brown spots.
White coating on leaves
Powdery mildew prefers the same type of habitat as Kalanchoe: warm, relatively dry areas. It may seem harmless at first and the plant may even thrive for some time.
Leaves fall: causes and care
The reason is most likely in the weakness of the plant. In the cold season, this happens due to the proximity to central heating. Most likely, the plant is on the windowsill near the radiator, and the air around it is too dry.
It is better to move your pet to a room with a lower temperature according to the following recommendations.
It not only decorates the interior, but also acts as an effective cure for most ailments and injuries. However, this unusual plant also gets sick, and therefore it needs care and proper care. If parasites appear on your pet, you need to take immediate action.
Main diseases of Kalanchoe, treatment at home
The main reason the appearance of the disease is improper care and poor conditions for the plant. Leaves and stems may develop spots, mold, plaque, small organisms, etc. You may not even be aware of why Kalanchoe leaves are falling off. What kind of Kalanchoe disease leaves and what else can cause improper care, let's look at it in more detail.
Insects love to breed in rich conditions. If you notice that your Kalanchoe is falling off, carefully inspect the stems and leaves. If you find scale insects, remove them with a paper towel and then throw them away. Also be sure to check the plant for larvae - they look like cotton balls. To prevent them from appearing, wipe the Kalanchoe with a delicate detergent.
Scale insects do not like moisture, so spray your favorite houseplant several times a week. And if bugs do appear, remove them and wipe the surface of the leaves with alcohol. After this, carefully wash the plant with a solution of soap and treat it with a special one. Simple and regular procedures will be enough to smell.
Did you know?Kalanchoe leaves contain juice that can heal cuts and also eliminate burns. In addition, the plant cleanses well problematic skin, if you make a mask from Kalanchoe.
Ticks
In addition, the leaves begin to harden, bend, and a brown crust forms.
Measures to combat ticks are quite simple: treat the flower with a soap solution or mineral oil. If the plant is neglected, the remedy "Akarin", "" or "Vertimek" is suitable.
These small insects are often found on Kalanchoe plants because they fly in from the street through a window. She is attracted to, oversaturated and. Small black or green aphids love the inside of the leaves, stem and trunk of the flower.
The bugs suck out the juice, covering the plant with a sticky substance, which prevents the Kalanchoe from breathing. At the same time, the aphid injects poison inside and poisons the plant.
How to deal with this? Using laundry or potassium soap, treating the entire flower once a week for at least a month. Also in an efficient way is
