Question: What Are Those Funny-Looking Growths on My Azaleas?
"I have funny-looking growths on my azalea shrubs. They're sort of light green bumps. What are they and how problematic are they for my azaleas?"
Answer:
Those unusual growths are called "azalea leaf galls" (or "azalea galls") and are not considered overly serious. They're caused by a fungus. Pick off the leaves where the azalea leaf galls occur and dispose of them properly: Do not put them in the compost and do not leave them lying around on the ground, lest the fungus spread to other branches.
Other than this shrub problem, however, I have found my azaleas to be relatively low-maintenance.
