I have a Japanese Crimson Maple tree that is about 8 years old and has been growing well but some strange light/brown spots are showing up on the usually bright crimson leaves.
Lately, we have been having an unusually high amount of rain and little sunshine to keep the balance. What is causing these spots on the tree? I have not seen pests but there are some holes in the leaves.
I would appreciate any help you could provide as it is a beautiful tree and will take whatever steps are needed to save it. I hope it is nothing to worry about but any advice you can offer is welcome.
