Acer

Question

I have an Acer of about five years old in a large pot. It seems to have a sticky substance on some of the leaves and some of the leaves are rippled. Other than that it’s quite healthy. What could these problems be please?

Answer 1

Sticky leaves are typically caused by either scale or aphids. Look closely at the underside of the leaves for small bumps. These articles will help you:
