Of course, you can propagate currants by cuttings, but until the fruits appear, it will take too long. It is much faster to do this by digging in the layers in the fall. Next summer, you can already get a small bush, which will quickly gain strength in a new place, and quickly give the first harvest.
On a bush with especially large and fragrant berries, choose one-year or two-year shoots growing on the periphery. We dig them in without separating them from the plant. Press with a board, stone or pin with a strong wire.
The buried branches receive nutrition from the mother plant, at the same time forming their own root system.
In the fall we add potassium and phosphorus, in the spring we feed it with nitrogen. In mid-June - early July, enough roots are formed on the part of the shoot that is in the ground in order to feed it on its own.
At this time, they can be separated from the bush with pruning shears or, if time permits, leave for another month. Then several root systems will appear on the layer, respectively, 1 branch can be cut into pieces and get more planting material.
We separate the layering from the mother bush with a pruner and plant it in a pit prepared in advance. We dig it out in the size 50 x 50 with a depth of 35-40 cm.Pour in 2 buckets of humus or compost, add mineral fertilizers, for example Nitrofoska (3-4 tbsp. L.).
Pour a bucket or two of water and give it time to saturate the earth - 1 hour.
Then we plant the currants in a permanent place, water.
We mulch with humus or compost.
Thus, you can propagate not only black currants, but also red and white, and gooseberries and other shrubs. If you didn't manage to do this in the fall, you can dig in the layers in the spring, and by the end of the summer you can get a full-fledged planting material.
