Slow growing. Because of the tap root they are
very rot prone, so use highly gritty compost with much drainage.
Requires half shade to part sun. Watering: waterings should be
rather infrequent to keep the plant compact and not to become
excessively elongated and unnatural in appearance,
watering it properly is often difficult
because this plant tends to crack open or rot if over-watered.
The fact that the plant retracts into the soil and assume a grey-green
colouring between watering, is perfectly natural and doesn’t cause any
Overwatering: Keep completely dry and cool in winter (An unheated
greenhouse would be perfect) or when night temperatures remain below 10°
C, it can survive low temperatures (appr. -7°C) for a short
period. Assure a good ventilation.
Propagation: Easy to propagate from
cuttings in spring (let them dry till the ends callous well). Then
replant them in fresh cactus soil that is ever so slightly moist,
and keep them that way till they root.
