Cherry tree damaged leaves

Asked May 26, 2020, 3:31 PM EDT

We have a mature cherry tree (I believe it is a Coosa cherry) in our yard which is dropping yellow leaves full of holes. The leaves still on the tree that are green are also full of holes. Can you tell me what is causing this, and how to treat it if it is a serious danger to the tree? Thank you.

Looks like the foliage of the cherry tree has been subject to a fungal disease called cherry shot hole. This has been common this season due to the abundant moisture we received and our cool wet spring. The fungus overwinters on fallen leaves, and good control can be achieved by raking and removing all fallen cherry leaves from the planting area. No chemical control is recommended.
