Q.Weeping cherry sapling trunk damage
Damage to weeping cherry Sapling has a hole gouged into it and a few vertical gouges. Is this from a woodpecker or frost? We planted it Sept and live in Kennesaw, Georgia. What treatment should we administer to the trunk?

The damage could be done by animals or birds, but likely is Sun scald.
Most trees can recover from small amounts of bark damage but you need to watch closely for signs of insects or disease.
