Cultivation:
This plant is easy to cultivate but very slow growing. Cultivate it in a
well
drained and
mineral substratum.
Water regularly, avoid
the use of
peat or other
humus sources in the
potting mixture. It need full sun, so it keep a compact and flat
shape. It does not tolerate intense
cold, but tolerates some cold if kept dry. Frequent transplantations of
the young plants protect the lower part of the stem from the
lignification, to which the plant has a tendency.
Reproduction: It is
propagated by seed. Sometimes old plants forms large clumps with several
joints - but the removal of one of these joints may prove fatal to the
plant.
