Japanese Maple Problems

Question

Last year the leaves curled and went brown. This year one side of the plant did nothing, and the other side got little red buds then stopped at that stage. The plant is 3 years old and has been blooming.

Answer 1

The tree sounds like it either has pests, such as aphids or scale, or has a fungus. I would recommend treating the tree with neem oil as it will treat both problems. It is organic, effective and safe for people, pets and beneficial insects.
