braburn apple tree

Question

My dwarf apple tree has brown/red spots on the leaves. The apples are not affected, also the leaves have been nibbled slightly at the edges. What could this be and how do I treat it if it needs treating?

Answer 1

This is caused by a fungus, likely apple rust. You can treat the tree with a fungicide and that should help. This article will help as well:
