Watering

Water weekly during active growth, reducing in winter; allow medium to dry slightly between.

Fertilizing

Use a weak orchid fertilizer every 1-2 weeks during the growing season.

Pruning

No pruning required.

Propagation

Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes -remove and pot them into sphagnum moss when the new roots are at least 2cm long.

Growing

Plants are best grown mounted on cork bark or wood if sufficient humidity can be provided. Alternatively, grow in a pot in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. It is a warm-growing orchid and the temperatures should not drop below 16°C. It can be grown similarly to Moth Orchid (Phalaenopsis) but requires much brighter conditions. Provide indirect light and higher humidity by misting regularly in spring and summer, then move the plant to a bright, room in autumn and winter. Ensure that roots dry-out between the waterings, especially in winter. See indoor orchid cultivation
