Grow in sharply-draining or cactus compost in full light. Water freely in summer, but allow compost to become dry in before watering again. Give a low-nitrogen feed three or four times during the growing period. Water less in autumn and keep cool and dry in winter. Provide winter protection, or grow in a container and overwinter in a greenhouse or conservatory. See houseplant cacti and succulent cultivation for further information
