Not the best time to be messing with roots, probably could have left them until spring before separating.
I typically give my seedlings at least one or two years before disturbing them.
Glad a local ended up with this tree, I contacted Will regarding purchasing it too, but apparently I was a bit late.
Looking good, keep up the good work
Don't do anything now, leave all foliage to hopefully drive some new root growth before it starts cooling down, and watch your watering carefully.
Good luck!
Welcome! both good choices for starter trees. Ground growing can be a good option if you want a big trunk quickly but with a few caveats, need to get the roots sorted before
placing in the ground and get some movement in the lower trunks as well. You do have to extract them every couple of years...
