How to grow

Cultivation

Grow in a free-draining cactus compost in a warm and sunny position on a windowsill or in a greenhouse or conservatory. Water regularly in summer, less in colder months and feed with a cactus fertiliser during the summer. Repot every other year or so. Resents waterlogging and also root disturbance as roots are shallow and weak. See houseplant cacti and succulent cultivation for further advice

Propagation

Propagate by offsets or by seed. Avoid disturbing the roots
