Features of planting and care

The soil for planting should be fertile and loose - preferably light loam with a neutral or slightly alkaline reaction (pH from 7.0 to 8.0). The location should be:
- completely open to sunlight;
- protected from the wind (for example, along a fence);
- without stagnation of moisture (preferably at a slight elevation).
In spring or summer, the site is dug up and 3–5 kg of compost or humus or 30–40 g of complex mineral fertilizer per 1 m2 are added. 500 g of sawdust or sand are embedded in clay soils. A month before planting, several holes are formed 50–60 cm deep at a distance of 1.5 m. A layer of small stones is placed at the bottom, and fertile soil is poured on top.
Shadrikh blackcurrant seedlings should be strong and healthy
Before planting, the bushes are kept for several hours in “Kornevin” or “Epin”, after which they are planted at an angle of 45 degrees, deepening the root collar by 5–8 cm. The earth is compacted a little, 2 buckets of settled water are poured out. For the winter, plantings are mulched with leaf litter, sawdust, hay or other material.
Caring for black currants of the Shadrikha variety is not very difficult. Basic Rules:
- Watering young seedlings regularly - a bucket 2 times a week. Adult bushes are given 20 liters twice a month. During drought, water weekly. In the heat of the evening, the crown must be sprinkled.
- Feeding is applied in the second year.Every spring they give urea - 20 g per bush. During the flowering period, complex fertilizer (30–40 g) is applied. At the same time, you can give boric acid - 3 g per 10 liters of water. During the formation of the berries, water with infusion of mullein or mown grass.
- Since the Shadrikh blackcurrant bushes are spreading, they must be tied to wooden supports.
- After heavy watering or rain, the soil is loosened.
- Weeds are removed as necessary. A layer of mulch - peat, dry grass, sawdust and other materials - will help drown them out.
- It is advisable to dig up young seedlings for the winter and cover them with burlap or spruce branches on top.
- Pruning is carried out every spring, removing all damaged and weakened branches. To form a healthy bush in the first years of life, you need to leave up to 15 strong shoots, and remove the remaining branches (in the fall).
- To protect the Shadrikh blackcurrant from rodents, in the spring a metal mesh is fixed around the trunk. You can also lay out sheets of rubber on the site. This smell repels moles.
