Culture:
Neobuxbaumia euphorbioides
are of easy culture and
can grow 15-20 cm a year. They are cold
intolerant. Make sure they are not exposed to freezing temperatures (
Hardy to -2°C) or they may die. They
need a well drained soil mix. Water regularly in summer but allow to dry
fully before watering again. During the winter months they should be
rather kept dry. Since they are rapid growers, they need plenty of space
for their roots. Repotting should be done every other year, or when the
plant has outgrown its pot. Sun Exposure: Light shade when young, full
sun later.
Propagation: From cuttings in spring (let them dry till the ends
callous well). Then replant them in fresh cactus soil that is ever so
slightly moist, and keep it that way till they root), or by Seeds (Seeds
should be sown in a well-drained soil mix. Surface sowing is the best;
seeds germinate in 14-28 days at 25° C .
