So I have a lemon tree and a dwarf orange tree that are both having problems. I'm not really sure what to do about them.
The orange tree has a powdery black mold that is growing on the leaves and there was only like 3 oranges on it this year.
The lemon tree is kind of a joke. I get around 10 off of it a year, but it has a weird looking thing on some of the leaves. A lot of the leaves are also yellow.
