How to grow
Cultivation
Plants are best grown in a pot in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. It is best to stake each cane to keep the upright form when potted. If grown in a basket, the plant will develop more pendulous form. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. Provide dappled shade and higher humidity in spring and summer, then move the plant to a bright, but cool room in autumn and winter. Reduce watering and feeding until warmer temperatures initiate flowering and new growth in spring.
Propagation
Propagation by seed is only possible in 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.
Suggested planting locations and garden types
- Houseplants
- Conservatory and greenhouse
Pruning
No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are at least three, younger, thick, leaf-bearing canes on the plant.
Pests
May be susceptible to scale insects, aphids, mealybugs and red spider mite.
Diseases
Generally disease-free.
