Plum Tree

Question

Plum tree did not produce or hold what litte fruit on tree to maturity. Leaves are turning brown with holes and some are skeltonized. I think it was tent worms that engulfed one whole branch and have seen Japanese beetles. There is also an area on a large branch that looks like there is sap coming out of it. I just want to get my tree back to good health, if possible. Thanks for any information you can give me. Judi

Answer 1

Japanese beetles will do the damage you describe. This article will help with getting the Japanese beetles under control:

I would also get the tree on a regular spray schedual for pests and fungus. This article will help you with that:
