Q.Azalea Flower Buds
This spring, many of the flower buds on my azaleas turned brown from the center out and, of course, did not open. Some bushes have a dozen flowers, all near the ground, and some have none. One bush is blooming beautifully. Was it the cold snap after a warm period, or is some disease attacking the buds?
