Cultivation and Propagation: is a a much decorative frost hardy cactus easily found in cultivation. Soil: Grow it in a rich and particularly draining substratum, as it is very sensitive to rottenness when in presence of humidity and low temperatures and let the soil dry out between waterings. Water: In summer, during the vegetative period, it must be regularly watered, but allowing the substratum to completely dry up before irrigating again; in winter, it’s to be kept dry. Preferable not to water on overcast days, humid days or cold winter days. Hardiness: The plant is tolerant of temperatures down to 10° C (or less) if kept dry and in a dormant state during the winter. In wet winter areas it is recommended to keep the plant in a sunny greenhouse enclosure to keep dry and protected from wet conditions. However in cultivation it is better not to expose it to temperatures lower than -5° C, even if in an aerated and protected location In presence of high atmospheric humidity avoid any frost as it is particularly sensitive to root rot. Outdoors this plant is very adaptable, as long as you avoid excessive humidity in the winter months. Exposure: It need full sun exposures with ample airflow for best appearance, but, as a former mountain dweller, does not care for extremely high temperatures in summer. Propagation: By seeds and by cuttings, provided left drying up well, in summer.
