Q: My beloved 26-year-old-plus azaleas have suddenly developed what looks like a major gall infestation in the last 48 hours. Examining the plants leads me to believe that it starts at one spot on each leaf. The leaf thickens and starts to grow from that spot, curls into a ball or cigar shape while remaining green, and then develops a white powdery appearance. The inside of the gall is hollow. Some have a small amount of weblike material, but it is very little and no larvae are visible. Any information or advice on this would be greatly appreciated.
