Beautiful flowers - dahlias, can be successfully grown not only in a flower garden, but also in pots. For this, varieties are chosen that have a small root system. Suitable for container growing curb, miniature, pot-dahlias.
The choice of packaging for planting
The volume of the pot for planting dahlias depends on the size of the root system. Low-growing varieties have small roots, it takes 5-6 liters to grow one plant. For medium-sized ones, you will need 7 - 10 liters, for tall ones, at least 20 liters.
For planting use:
- Clay pots;
- Plastic pots and buckets;
- Wicker baskets and containers;
- Wooden boxes.
Clay and ceramic pots allow air to flow to the root system well, do not overheat, and look very attractive. The disadvantages of such containers are high cost, fragility, high weight. Be careful when using containers in which flowers have already grown.
From fungi and harmful microorganisms, the pots are treated with disinfectants that do not contain chlorine.
Plastic pots, buckets and containers look good, lightweight, and inexpensive. But the root system of plants growing in such a container often overheats, the roots may not have enough oxygen.
Wicker baskets with flowers look very decorative. They are lightweight, breathable, the roots are protected from overheating. The only drawback of wicker baskets is their fragility.
Wooden boxes are great for planting dahlias. The tree is air permeable, the roots do not lack oxygen. The disadvantage of wooden boxes is that they are not very decorative. To make the boxes more attractive, they are painted with oil paint, decorated with ornaments and drawings. But, the painted tree stops letting in air, the plants develop in such boxes worse.
Landing dates
Potted dahlias bloom 40 to 50 days after planting. To get a flowering plant early, dahlia pots can be placed in a warm, well-lit room. In a city apartment, a dahlia will grow well on a heated balcony.
If the flowers are planned to be grown immediately outdoors, the sprouted tubers are planted when the air temperature is at least 12 degrees at night.
If it is possible to place dahlias in pots indoors before the end of the frost threat, planting can begin at the end of March. If the tubers are planted earlier, it is necessary to supplement the seedlings.
Seat selection
Growing dahlias in pots is convenient because they can be placed anywhere: on the veranda, in the garden between trees, along the paths. A row of pots can visually divide the area into zones.
Best of all, these flowers will grow in a sunny area, protected from strong winds. Slight shading is allowed in the evening.
Priming
One of the most important steps in growing potted dahlias is soil preparation. The soil should be loose, breathable, and contain all the necessary nutrients.
The earthen mixture can be purchased ready-made, or you can prepare it yourself.The finished mixture is selected with the marking “for flowering plants”.
To grow dahlias, add to the garden land:
- Sand;
- Humus;
- Complex of microelements;
- Rotten manure;
- Perlite.
All components are thoroughly mixed, large stones, lumps of clay and other debris are selected from the soil.
Add organic fertilizers you should be very careful in the soil, dahlias in pots do not like an excess of nitrogen in the soil. Overfed with nitrogen fertilizers, dahlias do not bloom well, the tubers of such plants hardly endure wintering.
Perlite is added to the soil in order to protect the root system from waterlogging. Granules of this substance quickly absorb excess water.
Landing
Planting dahlias in pots won't take long. When containers are ready, tubers, soil and drainage can begin to be planted.
A drainage layer is poured at the bottom of the pot, at least 15 cm high. The roots of dahlias do not tolerate waterlogging, if after showers or abundant watering water remains in the pot, the flowers may die due to lack of oxygen. Make sure the drain holes are not blocked.
The drainage layer is covered with soil, the size of this layer depends on the height of the container. At least 20 cm should remain to the edge. The soil must be moistened and slightly crushed. The tuber is placed sprouts up, sprinkled with soil, without deepening the root collar. The soil must be carefully compacted.
The pot is placed in a bright, wind-protected place. A few days after planting, the dahlia is not watered, only the soil is sprayed. Watering begins when absorbent roots form on the tuber.
Care
Keeping potted dahlias is easy. They do not need weeding, protection of roots from pests. They can be moved if there is a threat of frost or a hurricane, and then put back in place.
Dahlias growing in pots require:
- Watering;
- Treatment for sucking insects;
- Loosening the earth;
- Fertilization.
Watering is carried out depending on the air temperature. In cool weather, dahlias are watered no more than once a week. In hot weather, the plant may need daily watering.
Potted dahlias are very much harmed by sucking insects such as aphids. It is necessary to carry out treatment with insecticides 2 times a month.
The formation of an earthen crust must not be allowed. It interferes with the free flow of oxygen to the root system. After each watering, it is necessary to loosen the topsoil.
Potted dahlias need a lot of potassium and phosphorus for a bright, long-lasting flowering. Fertilizers are applied weekly when watering, or using a foliar application.
Growing dahlias will not be difficult, this flower will gratefully take care and care, responding to them with magnificent flowering.
