Azaleas and Leaf Gall

Asked May 20, 2018, 1:32 PM EDT

This time of year, how aggressive can I prun my azaleas that have leaf gall?

Calvert County Maryland shrubs exobasidium gall

This is Exobasidium leaf gall, which is not uncommon in wet springs. It does not hurt the plant, and you can do your normal pruning right now if you need to.
You could just pull them off and dispose of them now too, which will make them less likely next season.
