In order for the plants on your site to look their best, you need to understand the peculiarities of planting and caring for each species. Combination bright colors are able to give annual and perennial species dahlia.
General information about dahlia
The dahlia, or dahlia as it is scientifically known, belongs to the Asteraceae family.
According to various sources, the genus of this plant includes from 4 to 42 varieties. The plant was first noticed in the mountains of Guatemala, Mexico and Colombia. From these countries, the first representatives of this species were brought to our country.
IN landscape design low-growing varieties used to form arrays, borders or edgings. Other species look good in compositions in flower beds and in group plantings.
For single plantings, it is better to choose large, abundantly flowering varieties.
Those plants that are supposed to be cut must have a strong and long stem. Annual plants After flowering they are thrown away.
The dahlia can safely be called the queen of the garden plot. The splendor of shapes and colors decorate the garden with luxurious flower beds with lush greenery and colorful inflorescences.
The advantage of these spherical flowers is that the riot of colors lasts until late autumn. These are the only summer plants that have this property.
Criteria for choosing a landing site
When choosing a place to plant dahlias, you should remember that these flowers do not like drafts. In this case, the place should exclude air stagnation.
In addition, dahlias love the sun. Therefore, shaded parts of the site should be excluded.
The special structure of the soil will also promote the growth and flowering of dahlias. The soil should be drained and easily allow water to penetrate into the deeper layers to nourish the roots.
Heavy and depleted types of soil are not suitable for this type of plant. You also need to exclude poor and overly damp lands.
The nutritional value of the soil in this case will be of paramount importance. It can be enriched with humus and compost. These measures will lead to increased soil fertility.
This procedure must be carried out in advance, since the soil must settle. Other beneficial additives will be added directly during planting.
Planting dahlias according to all the rules
Before planting, the bed must be re-fertilized. Non-leaf compost, which needs to be scattered over the surface, is suitable as a feed. In addition, you can use a few handfuls of wood ash. It is better to use a rake for mixing.
For each root, you need to dig a hole 2 or 3 times larger than the roots themselves. After immersing the roots in them, about 7 cm should remain free.
If tall varieties of dahlias are used for planting, then it is better to pre-install supports so that later, when placing them near an already planted plant, the roots will not be damaged.
Planting is done quite deep. The stem should sink about 5 cm into the ground.
Immediately after planting, the plants should be watered generously with water at room temperature.
The ground around the seedlings should be covered with crushed bark and sawdust. This mulching will save young shoots from being eaten by snails.
Making a good dahlia bush
As the seedlings grow, they form into bushes. A plant grown from a tuber is created by removing the smallest shoots. Only the 2 largest and strongest are left for further growth. It is important to carry out this procedure as early as possible.
If propagation was carried out using cuttings, then only one stem can be left. In this case, you need to pin it on top above the third sheet. Then you can get a lush bush from one stem.
To large-flowered varieties were lush and beautiful, it is necessary to remove those shoots that appear in the axils of the leaves. This will save useful elements for the growth and development of the main flower.
If the bush turns out to be too thick, then you need to provide it with the necessary ventilation. To do this, it is enough to remove all leaves from the trunk at a height of 40 cm.
If the choice fell on small-flowered varieties:
then caring for them will be much easier. In this case, there is no need to form bushes.
Watering dahlias and feeding them
Immediately after dahlias are planted, they require daily watering for a week. After this, watering occurs less frequently. The amount of water is reduced so that the soil does not dry out.
To maintain optimal humidity the soil should be mulched. Humus, compost and peat are suitable for this. However, regular watering is not excluded.
The hotter the days, the more often you need to water the plants. After each watering, it is necessary to loosen the soil, remove weeds and similar regular procedures.
If watering rules are not followed, much fewer buds will form. Such bushes will be less lush, and their flowering will not be as abundant.
Feeding should be done mineral fertilizers or organic according to the schedule 2 times a month. The optimal temperature for the growth of cuttings will be 16-18 degrees. Temperatures below 7 degrees will not allow you to grow a full-fledged plant.

During the flowering period, dahlias turn summer garden into a colorful fairy tale filled with bright scenes and sunshine. The variety of these flowers is such that they satisfy the refined tastes of even the most demanding gardeners. Despite the wide palette of colors and extravagance of flowers, there are still some difficulties in the skillful use of dahlias in garden design.
Various forms of dahlias
Sunflowers are good companions for dahlias, not only because of the intense color of the inflorescences, but also because of their size. Sunflowers protect the thin stems of dahlias from wind damage. And it is not necessary to plant only annual sunflowers. Even though perennial helianthus are not so tall, they are also good protection from the winds for our dahlias.
In a flower garden with dahlias, the rule often applies: less is more. Instead of various flowering plants, which will compete with dahlias in beauty and variety of colors, you can use only two - maximum three varieties of dahlias, diluting them with filigree ornamental cereal grasses. Perhaps, ideal option is millet, giving the flower garden a beautiful golden yellow or red-brown tint, which harmonizes perfectly with fiery red dahlias. Tall cereal grasses, such as Chinese, are excellent as a backdrop.
When choosing two or three varieties for a dahlia flower garden, you should take into account the size and shape of the inflorescences. So, spherical and pompom dahlias, or cactus-shaped dahlias with deer-antler shaped dahlias, go well together. A composition of dahlias with simple and lacy inflorescences looks impressive.
An important aspect when composing a composition is not only the size and shape, but also the color of the inflorescences. If you choose a multi-colored variety from one class of dahlias, then dahlias from another class should be monochromatic. Using different varieties of dahlias of the same class, you can create a smooth transition of shades, which gives a special charm to the flower garden, or limit yourself to one color, choosing varieties with various forms inflorescences.
Dahlias and annuals
Perhaps the most popular composition is the combination of dahlias with annual flowers, since when digging dahlias in late autumn, you do not need to take into account their annual companions. Thus, good flowerbed partners for dahlias can be double and simple zinnias (Zinnia elegans), cosmos (Cosmos bipinnatus), annual asters (Callistephus chinensis), and lobelias (Lobelia fulgens) that match them in color and shape.
Dahlias look great in the company of perennials and annuals. A composition of small-flowered dahlias of yellow or orange color in the friendly company of Helenium, perennial sunflower (Helianthus microcephalus), Pennisetum setaceum, and marigolds (Tagetes) always attracts attention. The morning glory sweet potato with dark foliage gives a beautiful contrast to the composition. Depending on the size of the flower garden, dark-leaved varieties of sedum, heuchera, and rudbeckia are also excellent.
If you love the elegance of the cool, fresh colors of summer, then an arrangement of white and purple dahlias combined with different varieties Phlox paniculata of similar shades. The composition is completed by white or purple asters, as well as feathery feather grass.
If you want to create a flower garden full of expression, fire and passion, then your colors are flashy red and cool white! And here it is very important to choose the right red tones of dahlias and their companions so that they suit each other and are not very different from each other. For red dahlias from white companions, the following are excellent: white toadflax (Linaria purpurea "Alba"), veronicastrum virginicum (Veronicastrum virginicum "Diana"), white phlox, white varieties of autumn anemones, cape grass (Aconitum napellus "Schneewittchen").
For red companions, you can choose, for example, (“Gardenview Red” and “Sqaw”) or Lychnis chalcedonia.

Good to know
A dahlia flower garden needs care even during the flowering period. To prevent flying petals from sticking to green leaves, it is necessary to cut off the inflorescences at the first signs of wilting. Large dahlia bushes need to be tied to a support so that the wind does not break their shoots with heavy inflorescences. A boxwood border approximately 50 cm high can serve as a beautiful alternative. It will not only hide the inconspicuous stems of dahlias, but will also serve as a good support for them.

Among the dahlias there are a huge number of different types, differing in shape, color and other parameters. This diversity is used to advantage experienced flower growers when decorating flower beds. In the latter, you can harmoniously combine various terry varieties. In addition, there are semi-double species that look no worse.Particularly interesting are the flower beds, which contain specimens with inflorescences shaped like a disk with several tongues.

Dahlias are painted in almost all colors of the palette, which allows you to brightly decorate your flower beds. Pastel shades are especially attractive when decorating flower beds. The peculiarity of dahlias is their extreme attractiveness, both individually and in pairs with other flowers. There are various schemes, which, when decorating a flower bed, suggest focusing on a specific variety. This option looks advantageous in the central part of the flower garden, and its outskirts are decorated with shorter plants.
Unlike other flowers, dahlias do not require special care conditions. Like most plants, they need warm weather, direct sunlight and proper moderate feeding. Otherwise, the flowers become weak and do not produce abundant blooms.

Flowerbed design
In order for a flower bed with dahlias to look great, you need to resort to various tricks.
The most successful place for arranging a flower garden is considered to be the area where daytime always hits sunlight. There may be bushes, but they should not be too tall or dense.
The plot of land must have flat surface. It is best to use terraces where you can successfully combine different varieties these flowers. If dahlias are first grown as seedlings and then transplanted into a flower garden, the plant will bloom for a very long time. This is usually the period from July to October.
There are cases when gardeners prefer to plant dahlias on personal plots. They also look extremely advantageous in park areas, alleys and numerous intersecting paths. You can also arrange a flowerbed in front of buildings and structures - this is how it will serve exquisite decoration for the latter. But for this you need to correctly calculate the size of the flowerbed. Its width and length may vary. The shape of the flower bed can be in the form of a rectangle, triangle, oval, etc.
If the area is problematic, for example, there is high level groundwater or heavy precipitation, it is better to choose a surface with a slight elevation in the central part. The most beautiful flower beds are those in which dahlias are planted according to variety. In this case, you need to adhere color palette, plants should be monochromatic. To make the flower bed interesting, you can create a border of flowers. For this purpose, low-growing varieties of dahlias, such as pom-poms, are used.
Along the alleys and paths of parks and squares, mixborders are often planted, which include different varieties of large-flowered dahlias. There can be both annual and biennial plants. Feature of the mix: blooms in autumn, summer and spring. Flowers are planted separately, in thoughtful groups of 3, 5 or 10 plants of the same variety.

The flower beds on which dahlias are planted are great solution for any gardener. To enhance the result, you can combine dahlias with other types and varieties perennial plants. And to achieve the highest effect, you need to use the recommendations of specialists.
Perennial and annual varieties of dahlias require equal attention, but flowers that grow for more than one year also need winter care. It pays off with a magnificent flower garden garden plot for many years. Annuals are planted with seeds immediately open ground or using seedlings.
We plant and care for dahlias according to all the rules
Preparing tubers.
- The stored tubers are taken out in April, the damaged areas and dry roots are carefully cut off, and then the cuts are treated with brilliant green.
- They should then be placed in a small container with prepared soil or peat for short germination at a temperature of 18-20 °C.
- Tubers with shoots that have appeared are planted in the ground at the end of May.
- But many gardeners, preventing the degeneration of the plant and increasing the number of plantings, divide the tubers, leaving buds and a root collar on each part.
Landing in the ground.
At the end of May, the earth has warmed up enough, and it is time to plant dahlias.
- The prepared holes should be approximately three times larger than the roots to be planted.
- A little compost is placed at the bottom, then the tuber is laid and buried in such a way as to leave the top of the germinated stem on the surface of the ground.
- For tall varieties immediately install the support.
- The plantings are watered and mulched with a layer of sawdust to prevent drying out.
Subtleties of care
Fertilizers.
Dahlias are weak root system compared to green aboveground mass. Therefore, the plant is in dire need of sufficient moisture and fertilizing. If the plant blooms in separate containers, it can be fed several times liquid mullein at the rate of 1:10.
Open ground dahlias are fed twice a month, alternating organic fertilizers with minerals, for example, an infusion of bird droppings in a ratio of 1:20, mullein 1:10 or 15 g of ammonium nitrate per 1 cubic meter. You can deposit later potash fertilizers and superphosphate (30 g per bucket of water).
Mulching
Mulching is one of the techniques that avoids frequent loosening of the soil, saves from slugs and helps the soil retain moisture longer. After watering, which is done generously 1-2 times a week, the soil under the plant is again covered with sawdust and crushed tree bark. For this you can use straw, peat, even newspapers or cardboard.
Dahlias have a hollow stem, and the plant mass can be simply enormous, and therefore for tall varieties it is recommended to immediately install a support next to the plant when planting. A splint will save a broken stem; you need to carefully apply a thin stick or branch and secure everything.
U high grades dahlia is recommended to limit flowering. This is done to make it more decorative. For the same purpose, the lateral shoots are also removed, which can then be planted as cuttings. Low-growing dahlias are not pruned; their small bushes are already cultivated to produce a large number of beautiful flowers.
Protection from pests and diseases
A way to combat meadow bugs, aphids, and thrips that feast on greens can be spraying with soapy water (1 liter of water and 300 g laundry soap), tobacco solution or purchased insecticides. When slugs and earwigs appear, the plants are treated with a decoction of celandine.
To avoid the appearance of blackleg on plants, the soil is treated with a weak solution of potassium permanganate before planting. But when white or dry rot appears, when the plants begin to dry out and rot, and to prevent diseases, the bushes are disposed of and the areas are disinfected with copper sulfate.
The same thing has to be done with plants whose leaves have spots, veins become lighter, and the flower begins to deform and dry out. These are signs of a disease such as viral mosaic.
Storing tubers in winter
Tubers are dug up in the fall after the first frost, cutting off the trunks and leaving a 5 cm portion. Wash thoroughly with water. For storage, you need a temperature no higher than 3-5 °C and a humidity of 60-70% in a room with good ventilation. Peat, sawdust, and sand can be added to the tubers.
If you have to store dahlias in an apartment, they need to be placed in plastic bags and tied. In winter, tubers are periodically inspected for damage or rot.
Residents European countries, such as Great Britain, Germany and even as “Northern” as Ireland, it is much easier than for us to grow dahlias. There is no need to dig up dahlia tubers for the winter; they are only covered with a thick layer of mulch in late autumn. That's all!
In our climate situation, such a number will not work.
Apparently, for this reason, beautiful dahlias are most often grown in beds, which is only suitable for growing cut flowers for bouquets. What if you try to grow dahlias in a flower garden, choosing suitable partners for them?
I am convinced that it will turn out great if you simultaneously comply with all the requirements of agricultural technology.
Dahlias and companion neighbors
1. Cannas look very impressive next to dahlias - powerful plants with lush decorative leaves and beautiful flowers.
Canna leaves can be green, purple, violet, almost black and even striped. The flowers are most often red, pink and yellow. IN favorable conditions they bloom from July until frost. The agrotechnical requirements of cannas and dahlias are similar; cannas also require a sunny place protected from cold winds, deeply cultivated loose nutritious soil and abundant watering.
To ensure more luxuriant development, the eland is given hot bedding. For this purpose, fresh horse manure is placed in a hole 70 cm deep in a layer of about 20 cm and covered with the same layer of earth on top. Cannas are planted in the ground after June 10, after the threat of frost has passed. In August, cannas, like dahlias, need to be earthed up to prevent freezing of the root collars.
At the end of September - beginning of October, the cannas are removed from the soil with a lump of earth and sent for storage.
In March, they are shaken off the ground, old roots are cut off and divided according to the number of freely separated shoots of the rhizome. The separated rhizomes are laid out in a warm place and occasionally carefully sprayed warm water, avoiding rotting, after the leaves appear, they are planted in pots.
2. Decorative annual sunflowers (Helianthus annus) up to 2.5 m high, with huge multi-colored inflorescences, are good next to dahlias. Sunflowers bloom from mid-July to September. They do well in any sunny place garden soil. Seeds are sown in April-May in open ground to a depth of 2-5 cm. Flowering will occur 75-80 days after emergence. They do not need special care.
3. Incredibly impressive next to dahlias are amaranths - annuals with powerful erect stems 75-150 cm high. They have large elegant leaves with an elongated top, green or brownish red. Amaranths bloom from late June until frost. There are many varieties, interesting varieties are both those with drooping inflorescences and those with erect ones. Next to red dahlias, amaranths with purple-red leaves and erect burgundy inflorescences look gorgeous; the beauty of white and pale yellow dahlias is emphasized by amaranths with greenish-white inflorescences. These fast-growing annuals prefer a sunny location, light, nutritious soils with sufficient lime content, do not tolerate waterlogging and high acidity soil, in a word, everything that dahlias love.
4. Along the edge of the flower bed you can plant coleus, the decorative value of which is its variegated leaves. The main background of the leaves can be light yellow, pink, red and red-brown with contrasting patterns. The leaves are not only smooth, but also corrugated, fringed, and dissected. Coleus grow quickly. They require a sheltered, sunny or semi-shady location and light, permeable, rich soil.
5. Another good companion for dahlias are zinnias, fast-growing annuals with erect, stable stems (depending on the variety) from 30 to 90 cm in height. Zinnias are grown for their beautiful flowers of various colors, this also depends on the variety. They grow best in warm sunny areas, protected from the wind, on fertile light garden soil, bloom profusely and for a long time - from mid-June until frost.
Well, the project of our flower garden is almost ready. Find a sunny, quiet place for it, prepare rich, light soil, required quantity de-lenk dahlia and canna, as well as coleus cuttings, stock up on amaranth seeds, decorative sunflowers and zinnias, and in August you will get a wonderful bright picture.
Dahlias: planting and care
To grow dahlias, you need a sunny place, protected from cold and strong winds, with good air circulation, lowlands and marshy areas no good. The soil should be rich and loose with a pH of 6.5-6.7.
In conditions middle zone grown tubers are planted in open ground at the end of the first ten days of June, when the danger of spring frosts has passed. Dig a hole on the bayonet of a shovel, drive in a stake 130-150 cm long (for gartering high varieties), put rotted manure and 20-30 g of superphosphate into the hole, mix everything well, water it generously and plant so that the root collar is 2-3 cm below soil level.
Further care comes down to regular watering, weeding, loosening and fertilizing. In mid-August, dahlias should be earthed up to a height of 8-12 cm to protect the root collar from frost damage and stop watering and fertilizing. Dahlias are dug up at the end of September - beginning of October, depending on the weather. Before this, the stems are cut at a height of 8-12 cm from the root collar. The dug up tubers are dried in a well-ventilated room and transferred to permanent storage at a temperature of 3-7°.
