I feel somewhat reckless pruning this late in autumn, but the pepper trees are evergreen, and this one is very vigorous. So, what the hell.
The ongoing goal is to keep the size consistent with the somewhat narrow trunk. Which means this will be a small bonsai.
Looking over older posts, I note this was only bonsaied in December 2023, less than 6 months back. I noted at the time that the root structure was mostly pretty fine roots. I’ll leave this to grow for another year, but after that I’ll see what’s happening with those roots.
