It has a thick taproot and is susceptible to over-watering if kept in a non ventilated place. , sometimes it is  grafted to avoid root rot problems. Likes warmth (recommended minimum winter temperature 5° C) But plant kept perfectly dry can easily survive to winter night temperatures below 0° C. Sun Exposure: Suited for sunny-brightly exposure; can tolerate light shade.

Suited for airy exposures.
Needs deep pot and gritty mineral substrate with a very good drainage to accommodate its tap root. Water regularly in summer, keep dry in winter.

Propagation: Usually propagated from Seeds. (seldom produces offsets) or graft. Seeds can be sown in the spring or summer. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots.
