Answer 1

Lilacs can't take a lot of direct sun/heat until they're well established. If this is the problem, try to shade the lilacs during the hottest part of the day w/patio umbrellas or awnings.  You also might want to check your irrigation: too much as well as too little water can cause leaves to drop.  Aside from that, the only other thing I can think of is to check for pests like aphids (you'll find them on the underside of the leaves).  Good luck.
