Something is eating my lemon tree leaves!
I'm the proud new owner of a Eureka semi-dwarf lemon tree. I've noticed that something is eating holes in the leaves. I've posted pictures here and here. I'm pretty amateur at this, can anyone tell me what I should do to protect the tree? Oh, and is azalea fertilizer the right type of "acid fertilizer" for the tree?
