Looks healthy enough- nice shine to epidermis! Little corking/scar in the middle. Rotten roots are squishy (in cacto-lingo
) or just very sparse. If that's the case, then you back to the "making a cutting" stage. That columnar's roots should have some length to it. I just froze a Mexican Fencepost (@ 24") & in the process of checking everything to try to save something (couldn't
), I checked the roots. Soil bone dry & root ball was the size of 2 hands cupped together. Soil would be the only issue & you're working on that
! Good Luck!
