If the raspberry leaves turn yellow, then for the gardener this is a sure sign to analyze many things.
It is not only diseases and insects that can cause such a reaction.
An expert of the online publication "BelNovosti", agronomist and landscape designer Anastasia Kovrizhnykh reminds that the reason may also be improper care.
If you notice that it has become too hot outside, you cannot do without quality watering. Otherwise, the leaves will dry out and curl up. The harvest itself becomes noticeably lower.
If you notice that the leaves have become dry, then you should analyze your fertilizing system. This reaction in most cases indicates that the plant clearly lacks potassium and nitrogen.
It is important not only to water the raspberries, but also to do it correctly. You cannot use cold water: otherwise, problems will be guaranteed.
It is also worth making sure that the water does not stagnate under any circumstances.
