Maple/Acer

Question

I cut back my Acer last year as it was too tall. The new leaves are now coming out and this morning I noticed that there was a sticky substance on some of the leaves……..what is it and will it kill the tree which is much loved. Is there anything I can buy to stop this……..thank you x

Answer 1

This sounds like Honeydews, which is the residue from pests.
You can treat the tree with Neem Oil.
