Cultivation: Although regarded as a choice and difficult
plant, it
is not too difficult in a
greenhouse,
although it grows quite slowly.
It is sometime seen as a grafted plant but grows very well on its own
roots, too. Use well- permeable
mineral soil
with little organic matter (peat, humus). Water sparingly
from March till
October
(weekly during
summertime,
if the weather is sunny enough)
, with a little
fertilizer
added. keep
perfectly dry in winter
at temperatures from 5 to
15 degrees centigrade.
(but it is relatively cold-resistant and
hardy to -7° (-10°)C
for short periods).
In the rest period no high atmospheric humidity!!
They need a good amount of
light shade to full sun
this help to keep the plants
healthy, although
with slow
growth.
Propagation: Almost exclusively by seeds
that germinate rapidly.
Plants are sometimes grafted onto column-shaped cacti.
