Cultivation of astilbe
At home, astilba is grown from seed. Emerging shoots provide the necessary conditions. When warm weather sets in, plants are transferred to the garden bed.
There are certain terms when plant astilba on seedlings. Works are carried out in March-April. First, prepare the substrate and process the seeds. For cultivation astilby take equal amounts of sand and peat.
Soil mixture is steamed in a water bath to destroy pathogens. Another option for disinfection is to place the soil in a refrigerator. At sub-zero temperatures, the ground is kept for several months on the street or balcony.
For disinfection planting material is placed in a solution of Fitosporin. The use of the drug allows you to grow healthy and strong seedlings. s
For the cultivation of astilbe from seeds, containers with a height of 15 cm are prepared. To avoid picking up seedlings, cassettes with a cell size of 5 cm are used.
Seed planting procedure:
- Tanks are washed with hot water and filled with primer.
- A layer of snow 1 cm thick is poured on top. In the absence of snow cover, you can use their freezer ice.
- Astilba seeds piled on snow.
- After the snow melts, the seeds will be in the ground. Then the container is wrapped in a plastic bag and left in the refrigerator for 20 days.
Changes in temperature stimulate seed germination. When shoots appear, the containers are transferred to a warm, lit place.
Conditions for seedlings
Astilbe seedlings provide a number of conditions that include temperature, soil moisture and light.
Microclimate for growing astilby from seeds at home:
- temperature 18-23 ° C;
- lighting for 12-14 hours;
- regular watering;
- airing the room.
If the duration of daylight hours is insufficient for seedlings, then the installation of fitolamps or fluorescent devices is required. Lighting placed at a distance of 30 cm from the seedlings. Lamps include morning or evening.
Plants are watered with warm settled water. Moisture is applied under the root to dry the topsoil. To avoid high humidity, the room is periodically ventilated. Landings cherish from drafts.
With the development of 2-3 astilbe leaves, it is seated in separate containers. To minimize stress on plants, they are transferred to new containers along with an earthy clod.
2-3 weeks before transferring to the ground start hardening seedlings. Plants keep a few hours on the balcony or loggia. Gradually, this period is increased. Hardening will help astilbe to quickly adapt to the natural environment.
Landing in the ground
When growing astilba from seeds, it is transferred to the garden bed in May-June after the warm weather has been established. For plants fit the northern areas that are in the shadow of buildings or fences.
The flower develops well next to trees and shrubs. When planting on the illuminated site astilba blooms profusely, but less long.
The plant prefers loamy soil. The high location of groundwater provides soil moisture. In the spring, the plot is dug up and fertilized with compost in the amount of 2 buckets per 1 square meter. m
When planting astilba seedlings in open ground depends on the climatic conditions of the region. It is necessary to wait for warm weather and the last frost.
The procedure for planting seedlings in the ground:
- Preparation of planting pits with a size of 20x20 cm and a depth of 30 cm. A gap of 30 cm is left between the plants.
- At the bottom of each pit pour 1 tbsp. l diammofoski and 1 cup of wood ash.
- The wells are plentifully watered.
- Seedlings also watered and taken out of containers.
- Astilba is placed in a pit, growth buds are deepened by 4 cm.
- Roots of plants covered with earth, which is well tamped.
- The soil is mulched with peat, layer thickness - 3 cm.
Astilba is an unpretentious plant that requires minimal maintenance. At one place the flower grows 5-7 years, with regular care, this period reaches 10 years. Planting watered and periodically fed. Late autumn plants are prepared for winter.

After watering, the soil is loosened and weeds are weeded. After loosening, plants better absorb moisture and beneficial components. Shrubs recommended spud.
Astilba, grown from seeds, responds positively to fertilizing. During the season, fertilizers are applied 3 times:
- spring after snow melt;
- in mid-June;
- after flowering.
Nitrogen fertilizer is prepared for the first feeding. Nitrogen stimulates the development of new shoots. When hilling in the ground make rotten compost. Of the mineral substances used for plants, urea or ammonium nitrate. 20 g of the substance is dissolved in 10 l of water, after which watering is performed.
