Can water (presumably more than it wants) cause rhody blossoms to wilt prematurely? My rhodys were in full bloom and following several days of hot weather I gave one a very modest drink, but the soil here is heavy. Next day the flowers are wilted but the leaves look fine. My neighbor's yard gets no added water at all and is a burst of azalea and rhody color for weeks, even in full sun of those hot days, whereas mine bloomed a fairly short time. Is watering shortening my bloom time?
