I have two flowering cherry trees that are about 30 years old. The leafs of the trees have numerous (50 or more) small holes (2 mm) in them. I have been unable to find anything that seems to describe this condition. can you help?
Sounds like you may be referring to cherry shot hole, a fungal disease. This has been common this season and we have been getting many reports. You may notice yellow leaves with reddish brown spots. Often the center of the spot falls out creating a "shot hole" effect. Leaves may yellow and leaves fall. The fungus overwinters on fallen leaves, and good control can be achieved by raking and removing all cherry leaves from the planting area. No chemical control is recommended.
