How to grow

Cultivation

Plant with the crowns just above the surface and cover with moss to prevent the uppermost roots from drying out. Grow under glass or indoors epiphytically in a mix of 1 part fibrous loam, 1 part coarse sand and 2-3 parts leaf mould with a little charcoal. Filtered light, constant temperature (min 16 °C) and high humidity required in summer and full light in winter. In the growing season water freely and apply a balanced liquid fertiliser. Can be grown outdoors epiphytically in a warm, moist site or in moist, coarse, humus-rich soil. See houseplant cultivation for further advice

Propagation

Propagate by seed at 24 to 27°C as soon as ripe or propagate by division in winter
