Cultivation: Watering
Needs: The location has to be warm and bright, and it has to be in
direct sun. Otherwise the bodies tend
to elongate in cultivation, but
they should be protected from excessive heat and sun in summer.
In the spring
and late summer, water moderately.
Between these times
there are dry rest
periods. In the winter keep the plant absolutely dry.
The roots need a
lot of room, so make sure that the pot is large enough. Use regular
cacti soil with very good drainage.
Propagation: Seeds (offsets rarely), Grafting is often used to
speed growth rate and to create a back-up to plants in collection.
