There are two "Janet Craig's" in the office right now that look terrible (pictures attached). They're about 4' tall and have about 20 leaves between the two of them. I've been trying to spray water on them every once in a while and clean their leaves (what few they have left), but they don't seem to be getting any better (probably partly due to the weather). I am planning on propagating them using the stem cutting method when it gets warmer, since the plant is mostly leafless now. However, I admit I am scared of cutting off what remains alive on the plant. Any tips on propagation? Any other suggestions for getting leaves back on these plants? It would be much appreciated.
