First off, I am a pretty much a garden newbie. My hubby and I just moved from Cinti to Louisville and I'm finding that even though the zone is the same, the gardening is different. Our house has a 25 yr. old Bloodgood maple on the NW corner of the garage. It's a terrible spot for it--wedged between the sidewalk and the corner of the garage wall. It's been stunningly beautiful for most of the three months we've lived here. This weekend I've noticed that the color has started to fade and there are lacey leaves and brown tips. I see white insects-some with wings and some hard things attached to the leaves. I know the previous owner treated some nearby shrubs for scale before we bought. Is this scale and aphids both? I know the tree has suffered some stress because of our hot spell and the fact that we had siding put up about a month ago. Will all this be too much or can I do something and it will recover? Would pruning help to give it some extra room and air in its confined space or is the newly reflective vinyl siding bouncing too much heat onto it and causing it to stay under stress and vulnerable?
