An improperly chosen place of planting is the reason why the black currant leaves turn yellow

Shrubs in the garden should be located at a distance of 1 meter from any other crops, otherwise the plant will be limited in access to light and space. Leaves on such a bush will turn yellow and crumble. Berries in such conditions are tied up small, they are sour for taste.

The leaves of the currant turn yellow even when the bush grows either in sandy or in solid, nutrient-poor soil. In this case, the plant must be transplanted into a more suitable place or regularly introduced into the soil mineral and organic fertilizers.
