This slow-growing cactus isn't always the easiest species to cultivate, but can enlarge relatively fast when well grown. It is often seen as a grafted plant but grows very well on its own roots too.

Needs a very well drained soil with little organic material (peat, humus). Requires full sun to develop good compact growth and watering should be rather infrequent, to keep the plant flat shaped and not become excessively elongated and unnatural in appearance. Use water sparingly from spring to fall and keep perfectly dry in winter or when night temperatures remain below 50 °F (10 °C). It is hardy to 20 °F (-6.7 °C) for a short period. In the rest period no high atmospheric humidity. Ensure a good ventilation.

It is propagated almost exclusively by seeds. But the seedlings are tiny and very slow-growing and at first they take 1 or 2 years to reach the diameter of 0.2 inch (0.5 cm).
