flowering plum tree

Question

I have flowering plum trees that are losing their leaves. They also have little holes in the leaf with black around the holes. The branch is also dead.

Answer 1

This could be the onset of a fungal issue or insect pests. I would recommend treating the tree with neem oil, which will take care of both problems. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
