You are in philadelphia area. Is this tree in the ground or does it come in for the winter?
Does it look like this:

This is a fig tree. But I looked it up and you are probably in zone 7 (philadelphia area doesn't get as cold as Cincinnati??

) . I was thinking if it were fig it would have to come in for the winter, but not in zone 7.
Brown leaf margins like that can come from under watering. But: " The grass near the tree is very lush from the watering of the tree" can be a clue. Paradoxically the same symptoms can come from over-watering, if the ground is getting water-logged or the roots are getting damaged. Then the plant can have trouble taking up water.
Tell us more about how often you water...
Do you use synthetic fertilizer? Build up of salts in the soil can draw water away from the tree.
