You can find a lot of advice on the Internet on how to properly care for raspberries and currants.
It's easy to get confused, especially considering that some of the recommendations directly contradict each other.
It is much better to remember what you can’t do with raspberries and currants. This was told by the expert of the online publication “Belnovosti”, scientist-agronomist, landscape designer Anastasia Kovrizhnykh .
Firstly, spring pruning should never be ignored, even if the bushes were pruned in the fall.
Secondly, you can't leave last year's mulch. After removing the mulch, you must loosen the soil under the bushes.
Thirdly, for the first feedings you cannot use nitrogen fertilizers in ammonia form - they do not work in cold soil.
Raspberries and currants are better suited to saltpeter. For currants, 15-20 g of fertilizer per 1 sq. m is applied, for raspberries - 30 g.
