Culture: Neobuxbaumia euphorbioides are of easy culture and can grow 5-15 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 grafting.
