During the past two days, one of my holly bushes has decided to become a nudist. The leaves are falling off to the point I can't see the ground for the leaves. The leaves look healthy (no spider mite 'webbing' on the leaves or yellow spots, etc. ). Any idea what may be causing this? I live in Tulsa, OK.

My gut is that it is a water or nutrient issue. Based on your location, I would assume it has been somewhat hot, as it is in much of the country, which tends to cause many trees and shrubs to shed their foliage. Give them extra water to see if this makes any difference.
