Use mineral, well permeable substratum with little organic matter (peat, humus). Water sparingly from March until October, and keep perfectly dry in winter, at temperatures from 5 to 15 degrees centigrade. (but it is Hardy to -7°C for short periods). In the rest period no high atmospheric humidity!! Sun Exposure: Light shade to full sun.
Propagation: Almost exclusively by seed. Plants are sometimes grafted onto column-shaped cacti.
