I suspect that the trees are not getting enough water. Shedding leaves is the first sign of stress. They may regrow leaves if given enough water. Until the ground freezes continue watering.

Because they are heat and water stressed, they may have picked up a disease as well. Leaf spot disease are rarely fatal. Clean up all dropped leaves now and in the fall to prevent disease from overwintering in the soil. See the following website for additional details on what to look for.

Mulching around the tree will help avoid nicks from grass trimming equipment. Mulch will help retain moisture for tree roots and prevent grass from taking up all the available moisture.
