I have a dwarf Lemon tree that has been struggling ever since I got it in the spring. Now it has these little white shell like creatures on it with with what looks like a ruffle or hair around the edge of it. What is it & why is my tree not doing well. It was healthy when we got it home then most of the leasves dropped off & it started producing flowers and I had a couple of lemons start but they also fell off and now these weird little creatures are on it wherever there was a flower. |
