Trees and shrubs infested.

[hezahonker]

Hi, I am happy to find your group on sbcglobal news (...among the porn
newsgroups unfortunately (sigh))

I have so plants and shrubs located around the perimeter of our home as most
do. This year right off of the bat they had these little black mites all
over them eating them and thus killing them. We also have a small mature
tree of some variety that is sickly too. We sprayed the shrubs and plants
with insecticide and wammo they are gone thankfully. However, we are not
sure what to do with the tree. I can't see any mites on it at all but it is
clearly sick. The leaves are withered looking, but are still green. Also,
the depth of the bloom of the leaves is definitely more scarce than normal.

What can a novice do in this situation? Advice appreciated.
