How to Grow

Cultivation

Grow in a warm greenhouse in peat-free, epiphytic cactus compost, in bright indirect light with high humidity. Needs plenty of space to reach its full size. Water freely when in growth and apply a half-strength liquid feed monthly, keep just moist in winter. Flowers need to be hand-pollinated if fruit is desired; they are normally pollinated by moths or bats. See houseplant cacti and succulent cultivation

Propagation

Propagate by seed, sown at 19-24°C in spring, or by stem cuttings in spring or summer
