Answer: If you are having trouble rooting clippings, I would suggest you try "layering" the plants. To do a layer simply bend a shoot (in the zone where it is transitioning from succulent tissue to semi-woody tissue) until it cracks but not breaks completely in two. You can apply a little rooting hormone to the cracked portion.
Next bury the cracked section an inch deep in the soil, or in a container of potting mix sitting on the soil surface, and water it in well. Keep this area moist. In a few weeks new roots should have formed in the area of the wound. You can then sever the new plant from the "mother" plant and transplant it into its new location. Or, pot it up to nurse it along for a while before transplanting. Layering usually works even when trying to root cuttings is unsuccessful.
Thanks for the question!
