These small plants require repotting every few years. When re-potting, take additional care in handling as the leaves are somewhat brittle and can snap easily. Clay pots work exceptionally well for planting Kalanchoes. Ensure pots can drain well, and saucers can empty easily.
Native to South Africa and Zimbabwe.
