Any plans to handle the 4 "legs" on the base of the trunk?
Yes.
As it was taken off the ground less than two years ago, it is still getting used to the restrictions of the pot.
Japanese bonsai guys say about shimpakus: "one year aerial work, next year roots work".
So I will be patient and when the time comes I will take it out of the pot and sort the roots out. Maybe do some hard cutting on them. Time will tell! Lol
