Could you possibly send a picture of a leaf? Are the leaves turning brown before they fall? Do the leaves have red spots on them?

Thanks for getting back to me!! I am including a photo of the leaves. Yes, they are spotted while still on the tree and falling off as they brown. These three leaves where taken off each tree.
again, thank you for your help!!

Hi again,
Obviously, there is some kind of leaf spot disease, but it is really hard to pin down the exact culprit (bacterial or fungal) from photos. It is possible that your trees have entomosporium leaf spot caused by a fungus. This will not necessarily kill the tree, and there are some control measures you can take. Here is some info from NC State University: http://www.ces.ncsu.edu/depts/pp/notes/Ornamental/odin011/odin011.htm

The problem could also be downy mildew or some other bacterial leaf spot. Here is some information from the U: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/management-of-leaf-spot-diseases/#leaf-...

You can get a definitive diagnosis via the U's Plant Disease Clinic. Here is a link to their website: http://pdc.umn.edu/
