If you do not take proper care of your currant bushes, the berries will become smaller and more sour every year.
How to prevent a decrease in currant yields, says the expert of the online publication Belnovosti, agronomist, landscape designer Anastasia Kovrizhnykh .
In most cases, the cause is depletion or acidification of the soil.
Currants like neutral soils. If the soil is acidic, liming is necessary.
This should be done in the fall. Instead of lime, you can use dolomite flour or wood ash.
It is also necessary to apply fertilizers regularly, preferably three times per season.
