I have a largish collection of various succulents, sempervivums etc. In the autumn I brought them all into my (unheated) potting shed to keep them out of the frost.
Having checked them at the weekend I found that my Kalanchoe has suffered terribly from the frost. The leaves have all turned into mush.
I have now brought it indoors to the conservatory and cut off all the leaves and the top part of the stalk, the remaining stalk looks okay (unfrosted) and the top has now healed over.
I am going to keep it until spring to see if it recovers - am I wasting my time?!
