My lemon tree suffers from aphids. How to get rid of them? When I bought the tree, it had already a small lemon but then it fell off. I found white aphids under some of the leaves. Also, it is struggling to grow. I bought a liquid to mix with water and I have sprayed on the leaves. It seemed to have helped but if I don't spray for, say 2 weeks, then the white aphids are back, although in small numbers. What fertilizer should I use?
