Planting and caring for dahlias, features of agricultural technology

From mid-summer, all gardens are lit up with torches of flowering dahlias. A common perennial plant is so loved by gardeners that it is simply impossible to imagine a front garden without this crop. The widest palette of colors and shapes of lush inflorescences characterize a flower that enters the flowering time when the rest of the garden plants fall asleep. In order to enjoy the rich dressing of a dahlia for many years, planting and care must be carried out in accordance with all the rules. In this article, we will consider in detail the entire stage of plant vegetation from spring planting to harvesting tubers for storage.

Planting dates for dahlias

There is no definite time for planting dahlias, it all depends on the conditions and climate of the region where the culture is to grow. The most suitable period for landing in open ground is the second half of May, the beginning of June. With an early planting, when the earth has not yet warmed up, the growth of the dahlia will be slowed down, or even the tubers may not germinate at all. If planted later, the seedlings will burn out in the sun. It is optimal to transfer the tubers to the open ground when the threat of return frosts has passed.

Preparing dahlia tubers for planting

In no case should dahlia tubers be planted in the soil unprepared. First, inspect the planting material, remove dry and rotten parts, treat chips and cuts with brilliant green or a solution of potassium permanganate — this will help save the tubers from bacteria and pathogens. After processing, proceed to germination:

  • prepare boxes with soil (you can use peat, garden soil, sawdust, mixes bought in a store);
  • lay out the tubers, sprinkling them to half;
  • clean the boxes in a warm, lit place for 2 weeks.

When buds begin to appear, the tubers can be divided. Elongated shoots must be removed, but do not rush to throw them away — they can be used as cuttings.

Choosing a place and soil

When choosing a place, it should be remembered that dahlias do not like shaded, too sunny places and drafts. It is acceptable to plant in diffused shade under the crowns of trees, ideal places are near fences, hedges. Planting in places with close groundwater is not allowed — the slightest stagnation of water leads to the death of tubers. The soil is neutral (slightly acidic), fertile, it is good to add river sand, fine gravel to the planting pits for better water permeability. The landing site is recommended to be changed every year.

Growing and caring for dahlias

Dahlias are unpretentious plants and do not require special care, but the rules that apply must be systematic. In order for the flowers to please with large and beautiful pompoms of inflorescences, keep the distance between plantings (do not thicken the plantings), water and periodically feed the bushes.

Dahlias should be watered frequently, especially during dry periods, under the root. Make sure that water does not get on the buds. During the summer, fertilize at least 3 times, a solution of mullein and wood ash is perfect for this.

Do not neglect the pruning of the plant — dahlias intensively increase aboveground biomass, sometimes to the detriment of flowering and tuber development. At the very beginning of development, pinch, leaving the central stem and up to 4 side branches. Remove extra buds — on each shoot a central bud is laid (on a short peduncle) and two side buds. When the central one is removed, the lateral peduncles lengthen, the buds develop better. As a result, 2 large flowers will come out from one shoot, besides, they will bloom earlier.

Features of autumn care

Autumn for dahlias is a special time of the year when seeds and tubers are formed. Be sure to do the following during these months:

  • hilling — at the end of August, hill each bush to a height of 10-12 cm. This will help save root tubers from night frosts. Plants do not need to be watered at this time;
  • pruning — remove inflorescences as they fade. After the first frost, cut the stems, leaving stumps of 10-15 cm, but do not rush to dig up the tubers, let them rest for two weeks.

Preparing dahlia tubers for storage

Ripened tubers cannot be stored immediately, they must be prepared

  • Dug nests need to be cleared of the ground, cut off small roots and remove old tubers.
  • Rinse thoroughly.
  • Dry in the sun for several hours.
  • Inspect the tubers and treat with fungicides.
  • For storage, dahlias are placed in boxes or perforated bags and sprinkled with sand. Store in a dark room with an air temperature not higher than +5 degrees. The tubers are periodically sorted out and inspected, the rotten ones are immediately removed from the storage.

    The nuances of agricultural technology

    When growing dahlias, it will not be superfluous to know a few secrets that will help abundant and long flowering.

  • Lush bloom. In order for the bushes to bloom profusely, it is necessary: ​​removal of fading buds, timely pinching, moderate top dressing (with an excess of nitrogen, green mass actively develops to the detriment of budding).
  • Long flowering. Mass flowering in dahlias is observed in September, at the same time the plant may suffer from the first autumn frosts, after which a short Indian summer sets in. To prolong flowering during this period, wrap the bushes with lutrasil. This will help preserve the color and green biomass for later vegetative growth.
  • As you can see, it does not take much effort to achieve excellent results in growing dahlias. The sooner you start preparing the soil and tubers, taking preventive measures, the less time you will need to care for in the future.
