How to Grow

Cultivation

Grow in a shallow pot, in an airy position with good humidity. Grows best in houseplant compost or a mixture of medium to coarse bark with a small amount of sphagnum moss. Allow the compost to dry out between waterings and feed frequently with orchid fertiliser. See Orchids: indoor cultivation for further information

Propagation

Plant the fleshy stems that break off in sphagnum moss until roots form - approximately 6 weeks, cuttings can then be potted up into houseplant compost after about 6 months

Suggested planting locations and garden types

Pruning
