Berry crops require regular care and, in particular, proper pruning and fertilizing.
If we talk about currants, then with age the bush begins to bear fruit less and less. However, it can be rejuvenated, and then the harvest will be 2 times more and the berries will be large and sweet.
This is what experienced gardeners do in this case.
First, you need to understand the reasons, of which the bush has many, in addition to age.
It is possible that the plant was planted in the wrong place - red currants may not have enough light, while black currants, on the contrary, may suffer under direct rays.
Maybe it's time to deacidify the soil.
The bushes may lack basic moisture, which will cause the ovaries to fall off.
And the worst thing is diseases or pests.
If all these reasons are excluded, then it is time to carry out a rejuvenating procedure. Most likely, it will be a bush older than 5 years.
After the snow melts and before the buds swell, you need to thoroughly water the soil under the bush, and then dig up and remove the plant along with the root ball.
At the same time, if the bush has grown, it can be divided into equal parts.
Then choose a suitable place. An apple tree or honeysuckle, strawberries, onions, garlic can grow nearby. The new place should have moderate shade.
Plant a bush or divided parts, then cut off the above-ground part, leaving 5-6 buds, and water once a week.
