Masterpiece
As you can see in the above photo, and this closeup, I filled the empty space at the top of one of the 15# pots with old bonsai soil last year sometime, burying the trunk much deeper than it would eventually be planted.
It worked like a charm to promote tons of new roots close to the trunk, and above the giant ones I'm sure are in that pot. Just tipping the pot and shaking off the top layer revealed exactly what I wanted:
A cross section of the pot shows it clearly:
All those fine roots at the top are new. The old soil line is still visible where the dry part starts.
