Thanks, Bobby. Yes, I do get a little excited with the pruning saw, but in the long run the tree will be much the better for it. Encouragement coming from you, I'll take it!
As for the root base, I was discouraged about the ground layer at first but poking around yesterday found some signs of rooting at the level I needed. (
Old Thread) That was exciting to be sure. I am guessing when I take it out of this deep pot I will find it has bridged in places, but even a few roots will be progress!
