You may be dealing with anthracnose, a fungal disease on your shade trees. This is favored by cool, wet, spring weather. Trees may lose a large number of leaves in the spring or early summer when weather conditions are optimum for disease development. You may also notice brown or tan lesions along the leaf veins. Although disease symptoms can be very noticeable, anthracnose rarely has a negative impact on the health of mature trees. See our Plant Diagnostic website for more information http://plantdiagnostics.umd.edu/level3.cfm?causeID=1176
If you want to have them evaluated, a consultation by a certified arborist is who you are looking for. These professionals are experts on tree health and hold certification from the International Society of Aboriculture (ISA). You can search for one at www.treesaregood.org
