Planting can be done in spring and autumn.In regions with severe winters, they are planted in April. For an area with a temperate climate, a more suitable time is September. The landing pit is made in size: 40x60 cm, 3-4 weeks before the event. A distance of 150 cm is left between the seedlings. Between the rows - at least 200 cm.The excavated soil is mixed with 4 kg of manure (or compost), superphosphate - 130 g, potassium sulfate - 25 g. If the substrate is very sour, add milk of lime - 800 g per 1 sq. m, the substance can be diluted in a bucket of water and the earth can be shed. The root collar is buried 6 cm.

The foliar method is processed in July: for this, a mixture of boric acid is used - 2.5 g, manganese sulfate - 7-10 g, copper sulfate - 1 g, molybdenum ammonium - 2 g, - all these substances are dissolved in 10 liters of water and sprayed with foliage ...

The first 3 years, currants are not cut. The first pruning for crown formation is recommended to be carried out in early spring the next year after the first harvest. Sanitation is carried out twice a year: in March - before the start of sap flow and in October - after leaf fall. Be sure to remove branches older than 4-5 years. Adult plants are recommended to tie or make a low support for the branches.
