Tee
, that is exactly what my experience is, they wither, shrivel and one day go back into the soil, this time of the year. Basically it is from Aloe family and full of water, what happens to the water when temps are below freezing. Remember there is no metabolism going on in a separated leaf. How about putting the pot into a ziplock bag? No experience with this procedure since I propagate(plants) in spring, so no comments. Can they be preserved in bags in the vegetable crisper until spring when every thing goes mad over propagation(plants)?
