White flies are ruining my gardenia bushes!
Every spring they are over run with white flies and then the leaves have that thick
black coating on all the leaves. What can I do to prevent this or treat this. I have tried numerous online remedies, but I can not get the black off the leaves and eventually the bushes look awful. New growth does come in, but the inner leave always remain covered with black.
