It is interesting to me at least. I remember reading or being told that the Arabicums grow horizontally across the soil and not deep. When I first up rooted this tree, I could see where in fact this was true. It had a solid area underneath with no roots. All roots come from around the caudex perimeter. Unlike trees which have been cut off and new roots grown.
Sorry, not going to unpot to show roots. Something that I wish I remembered to do when transplanting.
