Testimonials

Svetlana Orlova, 45 years old, Moscow

I have been growing black currant Kupalinka in my country house for about ten years. I like the variety for its unpretentiousness and high yield with minimal maintenance. Its only drawback is its small berries, which makes picking difficult. The taste of the fruit is excellent, the aroma is pleasant. I renew the bushes every seven years, otherwise the productivity drops sharply. For the rest, I adhere to the standard rules of agricultural technology.

This variety does not cause any particular difficulties in care, therefore any novice gardener can cope with its cultivation.
