accidental supercropping, i knew it had a term lol, just did that to mine the other day, broke it completely off, only had a 1 -2 mm wide, paper thin piece of, bark/skin stuck on but i taped it off and figured what the hell, well see whathappens ( have done this twice so far and ended up cloning them successfully) and within a day she has recovered and obviously is getting more nutrients because of it. always keep a piece of tape handy when lsting, or some rooting hormone.
ever hear the myth u can cut right through a tree but if a small piece of bark is intact still, it can recover, i believe the same applies, cut through all the skin and you're screwed.
