There are quite a few reasons for yellowing of cherry leaves, but, as a rule, this symptom indicates that the plant has been affected by a fungal disease - coccomycosis.
We will tell you how to make sure that the cherry tree is infected with coccomycosis and what to do to cure the tree.
Why do cherry tree leaves turn yellow?
Typically, this fungal disease makes itself known in May or June – during this period, summer residents notice brown spots on cherry leaves.
They very quickly occupy the entire area of the leaf, as a result of which the latter, being a kind of energy supplier for the plant, wither and fall off.
The best environment for fungus development is humid and warm conditions. Trees with a dense crown and root shoots are at risk.
Since coccomycosis spores can survive even on fallen leaves, gardeners should definitely start cleaning them up as autumn approaches. To prevent infection, you should also get rid of all the fruits on the tree, and in the spring, dig up the ground next to it, removing weeds and shoots.
A couple more measures that should be taken by anyone who wants to defeat fungus are mulch and whitewashing with copper or iron sulfate.
Do not leave your cherry orchard unattended and watch the trees especially closely in the spring: as soon as you notice the first signs, treat the cherries with a 1% solution of copper sulfate before applying nitrogen fertilizers.
