Pruning fruit trees and shrubs is the most important agrotechnical technique, which allows not only to form the crown of plants, but also to prevent the development of diseases and increase fruiting.
Black currant pruning in your gardens should be carried out regularly and in a timely manner. Pruning also has a beneficial effect on the growth of annual shoots, on which larger berries then ripen.
But the currant bush should not be cut off after some time, but immediately after planting! This is necessary so that the bush begins to branch faster. Each shoot on the bush is cut off, leaving only 2-4 of the most developed buds. If the branches of the bush are weak initially, they often resort to pruning them to a hemp. Over the next 2-3 years, on currant bushes, all diseased, weak, thickened, old branches should be cut to the base, leaving only 3-4 well-developed young annual shoots.
If the growth of the bush is weak, then, without regret, several fruiting shoots of 2-3 years old should be removed. This pruning stimulates the growth of root shoots.
The pruning that forms the bush ends by 4-5 years of the life of the bush. At this stage, it already contains branches of different ages with different functions. It is better to leave about 10-15 branches of different ages on the bush, but keep track of the proportion: there should be 1-2 more one-year-old shoots, and 1-2 fewer very old branches. On adult bushes, branches of 5-6 years old are cut off, which already bear fruit poorly.
Black currant pruning is done in early spring. It is necessary to have time to do this before the buds bloom, and on black currants they tend to bloom among the first.
