Features of planting and care

The soil is pre-prepared in spring or summer:
- the site is dug up;
- if the soil is depleted, add a bucket of humus for 2 m2;
- if the soil is clayey, cover 1 kg of sawdust or sand per 2 m2.
A few weeks before planting, it is necessary to dig a hole 60 cm deep (the distance between the bushes is 1.3–1.5 m), lay a 10-cm drainage layer of small stones and fill it with fertile soil. The landing algorithm is standard:
- Soak the roots of Ruben blackcurrant seedlings in a growth stimulator - "Kornevin", "Zircon", "Heteroauxin".
- Place the seedling in the hole at a 45 degree angle and straighten the roots.
- Dig in with fertile soil so that the root collar goes to a depth of 5–7 cm.
- Tamp the soil a little. Pour 10-15 liters of settled water.
- Mulch with peat, dry foliage, sawdust, hay for the winter.

- Top dressing - in the spring, urea (20 g per bush), in mid-June, complex fertilizer (30–40 g) or organic matter (infusion of mullein, droppings, cut grass). A similar composition is fed after harvest.
- Pruning: after planting, all branches are immediately removed up to the third bud. A sanitary haircut is done every spring.Remove frost-damaged, weakened shoots. In the first 3-4 years, a total haircut is carried out in the fall, leaving 3-4 healthy kidneys.
- Weeding, loosening - as needed.
- Rodent protection - wrap the currant trunk with a net.
- Shelter in regions with frosty winters: the roots are mulched, they are insulated with burlap on top. The ends are fixed on the ground or on the skeletal branches of the bush.
