Some leaves on one azalea are getting thick and fleshy, turning from light green to a powdery white. Shrub is over 30 years old. Thanks for your help.

Azalea Leaf Gall is the descriptive name for the disease your azalea has developed. Symptoms include light green, fleshy, bladder-shaped galls that appear on the new leaves in late spring and early summer. The galls change from green to white to red to brown, covered with a white bloom. The galls eventually become hard and dry. It's a fungal disease that's fairly easy to control by picking off the thickened leaves and destroying them. You may want to prune your azalea a bit to help increase light penetration and promote good air circulation.
