Can anything be done with the "leaves" and/or "arms" of the frozen cactus. I have an arm/piece of one that I believe fell off because of the freeze and would like to know if I can start it. I would also like to know if I should cut off the parts of my cactus that are drooping down after the freeze. A couple of them are splitting away from the main part.
Any information would really be appreciated, since I know very little about them but truly love them.
