You have some really nice trees ... Killer little JBP, wonderful little trident, and doing great work on your large arakawa maple. The subject tree of this thread is going to be difficult to develop well, as alluded to by a couple of the posts above. The nebari is a little dicey, the lowest branches are heavy. So I think it will take a lot of work. May need to air layer for better nebari, get some new grafts down lower on trunk to be future primary branches, remove heavy branches and build a new top/leader? Looking at the tree from the pictures you posted, it looks like a total rebuild? No offense intended, you are doing great work. Curious to see what you make of this one!
