Q.What Happened To Our Plum Tree?
Our (mostly decorative) plum tree had its usual cover of white blossoms this spring. Late spring/early summer, the branches started to droop and the leaves started drying. Now it is covered in brown leaves. Is it a goner? Any special considerations in dealing with it?

You can tell if it is still alive by scratching off some of the bark. If it is green below, it is still alive. If so, examine the leaves and bark for any abnormalities such as fungal spots, knots on branches, holes in trunk, etc., so you know how to proceed. This information should help:
