sensitive to over-watering (rot prone),
and needs good drainage. Keep
drier and cool in winter. Needs
full sun. In
the summer they need an airy location in bright sun; well watered when
it's hot. To achieve the best spine density
give these plants lots of sun. In the winter
light, cool, and absolutely dry conditions.
Very cold resistant above -12° C or less for short periods of
In mild climate they grow well when planted freely outside
in well-drained soil.
