How to identify leaf problem on Newport plum tree

Question

We have a newport plum tree that has holes in the leaves. Is there a website to read about how to identify this problem and find a solution?

Answer 1

It sounds like insect damage either by adult or larval insects.  Look your tree over real well and see if you can catch the culprits.  This site can help you identify the problem and tell you how to treat it.  Good luck!
