you now have several strong branches in a relatie=vely short trunk space. I think you are setting yourself up for bulges with this many thicker branches. I would not have let all of them grow out like this.
Why don't you cover the nebari more, and try to get smoe growth there?
I was having this same thought....about the bulges.
My plan is to put it in the ground in a few years.
I think I'll bare root it next spring, sort out the roots, at least one of those nebari roots will have to go.
There may even be a whole other, larger nebari below the soil line.....in which case, all of the roots you see will be removed.
At any rate, plan to bare root and pot it for a year or 2, then go into the ground once a better nebari is established.
Once in the ground, maybe I can remove branches I don't want and grow the leader out for a good next trunk section.
I'm hoping that ground growing will kill any bulges, and thicken the whole trunk substantially.
