Question: How can I prevent the ugly, green-white galls I got on my azaleas last year?

Answer: Azalea leaf gall is caused by a fungus and effects plants under moist conditions in early spring. It’s ugly, true, but not really dangerous to the plant. You can handpick the galls before they turn white, and pruning low, overhanging tree branches nearby will help to improve air circulation around the plant, which can control the fungus.
