Q How can I stop azalea leaves turning white? MARY SMITH, VIA FACEBOOK
A Azalea gall is a fungal disease that’s usually worse in wet springs. It only affects Japanese azaleas and usually just a few leaves on the plant. At first the leaves look swollen, distorted and pale green, but as the fungal infection progresses, the swellings turn white as more spores are produced. There is no chemical control: carefully pick off and dispose of the affected leaves before they turn white.
