Prune to shape the plant, remove dead or damaged pads, or control its size. Use a sharp, clean knife or saw. Allow the cut surfaces to callus over for a few days before replanting or discarding to prevent disease.
Propagate from stem cuttings (pads). Allow the cut pad to dry and form a callus for several days to weeks. Then, plant in well-draining cactus mix. Rooting typically occurs within a few weeks.
Repot only when the plant has outgrown its container, usually every 2-3 years. Use a well-draining cactus or succulent potting mix. Choose a pot only slightly larger than the current one. Repot in spring.
