My sand cherry leaves are losing their color and look transparent in splotches. I have never had this problem before.
They are well established and have never done this before. It isn't all the leaves yet so I would like to treat it if possible. I have searched the internet with no results. Thank you for any help you can provide.
This could be due to an insect pest scarifying and skeletonizing the leaves, "cherry slug" is the larva of a sawfly, and Japanese beetles do this.
Neem Oil is a good treatment for mosts pests.
