Thanks everybody! Here's the plan: I'm going to weed/mulch around the sprouting stumps to give them as much sunlight/nutrients/room as possible. I'll give them some minimum winter protection (burlap screen to prevent sunscald/wind damage) and then I'll see what they look like in the spring. once I see the sprouts are growing, I'll select one or two (probably one for the crab; two for the dogwoods) and remove the others. Then we'll just wait and see what happens.
