Ok, the taller tree suddenly started to tip to one side a bit.. didn't think too much of it. But then, upon inspecting it, noticed some wierd growth abnormalities. Then, went on the inspect the smaller tree, and found a few on that one as well. Any ideas what's going on here? (I know I had aphids and ants.. but have treated for the aphids even tho there are still some there, it's not as bad.)
