Azalea/Camellia Leaf Gall: Pick Off Swollen Leaves Before They Turn Gray

Swollen, thick, pale leaves = leaf gall (fungus Exobasidium). Infected last spring.

Now

Pick off and bag all galls. Before they turn gray (spore stage). Don't drop on ground.

Prevent Next Year

Spray landscape fungicide just before leaf-out in spring, repeat 10 days later.

Trivia

Called "pinkster gall/apple." Pioneers pickled and ate them. Don't—you—most azalea parts are toxic.
