Azalea leaf spots

Question

I have two azaleas five feet apart from one another. My smallest one has brown spots on the leaves and they have now made way to my second azalea, which is much older and has never had brown spots. What causes this and how can I treat it?

Answer 1

It sounds like it has a fungus, which can be treated with a fungicide and that should help. If you can spot other indicators of a problem, we can give you more precise advice on how to treat it.
