Answer: Unfortunately, it sounds like your trees may be suffering from both insect and disease problems. You might wish to contact your county extension (736-3394) for a specific diagnosis of the problems and suggested remedies as well as recommendations for routine care of the trees. Although the sumac trees may be causing the cherries to need to compete for water and nutrients if the roots have encroached, or for light if they are large, it sounds like there is more at work than just that. I'm sorry about your trees.
