cv. TANSHI ZUOGEMARU
Origin:
Japan (Nursery produced
cultivar)
|
|
Cultivation:
Easily
grown in normal
cactus compost, requires good
drainage.
Water in moderation, keep drier in
winter.
Full sun to
partial shade in summer. In
humid
conditions, the
exudation of
nectar (if not completely removed by ants) can cause the formation
of
mould which leads to ugly black-colouring of the
epidermis. To prevent this, spray the plant with water to remove the
nectar. And provide very good
ventilation.
It flowers quite early, but needs about 8-12 years to reach the typical,
definite outlook. It tolerates fairly low temperatures as long as it is
kept dry (Frost Tolerance: Hardy to -3°C)
Propagation: Usually by grafting.
