Holly Bush Disease
My holly bushes have some leaves that have turned black and some have numerous small white deposits (about one quarter inch long) stuck to their backs. I live in Fairfax, Virginia and my bushes did sustain some snow damage this winter, but new growth and berries have appeared. The white 'stuff' is also attached to the back of the new green leaves. Is there some kind of spray for this?
