Cultivation: It is a summer-growing species that offers no
cultivation difficulties. It needs good drainage and very porous
substrate. Water regularly in summer (but do not over-water ). Wait for
the well draining soil mixture to be rather dry before watering again.
If it loses its roots, let the stem dry for a few days before
replanting. Keep rather dry in winter. Feed with a high potassium
fertilizer in summer.
Although it is cold tolerant (hardy to -12° C for short periods), one
should give it frost protection to prevent scarring. It tolerates
intense sunlight and needs a very bright exposure. Full sun is
indispensable to keep plant compact, with strong spines.
Propagation: Direct sow after last frost, although fairly slow, or
use offsets (if available)
