Cultivation and Propagation
It is a summer grower species that offers no cultivation difficulties. Lobivia crassicaulis has a fairly large tap root, and should be kept in a deep pot with a very draining mineral substrate. Water regularly in summer (but do not overwater ) keep dry in winter. Feed with a high potassium fertilizer in summer. Repot yearly until reaching about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter but can be done at other times. Do not water for a couple of weeks after repotting to reduce risk of root rot via broken roots. Repotting will increase size of stems. It is quite cold tolerant if kept dry (hardy to -12° C). Need a very bright exposure, full sun is indispensable to keep plant compact with strong spines.
Propagation: Direct sow after last frost, grafting or offsets (if available)
