It is very easy to grow and cold hardy as low as -12°C (or less).  This cultivar seems to do better with a little more water than most cacti. In fact, its cultivation requirements are really more like 'normal' plants than most other cacti. During the growing season fertilize them monthly with a balanced fertilizerSun Exposure: Outside full sun, but during hot summers, the cactus are subject to sun burning, so grow them in light shade, inside needs bright light, and some direct sun.. During winter month, put them in a cool luminous place and encourage them to enter winter dormancy by withholding water and fertilizer over the winter as they will etiolate, or become thin, due to lower levels of light. They are susceptible to fungal diseases if overwatered, but are not nearly as sensitive as many other cacti, especially in warm weather. They tend characteristically towards black rotted spots unless watering is moderate and only in hot weather, if kept damp through cold periods, they will invariably suffer.
