Linda, I just found this on the internet, about dividing heuffelii.
When you have separated the pieces, place them somewhere in a bright and ventilated area to dry. If they are not placed in a dry and ventilated area, there is a good possibility that they will begin to rot. I prefer leaving them for several days until the cut area is quite dry. If you are not sure whether they are dry enough, it is probably best to wait a few more days. At this point you can repot into containers, however, water should be withheld until you can see that the plants have begun to produce new roots.
Seems to me twit gave similar information somewhere here in one of the threads. Good sound advice. : )
