Last week, the question was: What is wrong with these azalea leaves?
These leaves are infected with a fungus known as Exobasidium vaccinii which causes azalea leaf galls. Azalea leaf galls are most noticeable during cool, wet springs and is usually a very minor issue. The galls are superficial and cause no long term damage. Getting rid of them is as simple as picking off the leaves and disposing of them. For more info, take a look at this Virginia Extension page.
