I found and purchased a different stewartia. It’s less ramified but has a larger trunk than the tree initially posted. Total height is around 6’. The grower says it’s a monadelpha but didn’t seem sure, so we’ll find out down the road.
Since it was dug out of the ground and I might be moving, I had to pot it up. I opted to build a grow box 19”x19”x 10” deep and filled it with a 50/50 mix of sifted pine bark and pumice. Its heavy but I wanted something sturdy..
The plan is to see what happens this spring. If growth is vigorous I’ll trim the branches in June-July. If it’s slow to recover it will be left alone.
