How to grow
Cultivation
Plants are best grown in pot, or mounted on cork bark or wood if sufficient humidity can be provided. Grow 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. Provide bright, but indirect light and higher humidity by watering and misting frequently in spring and summer, then move the plant to a bright, cooler room in autumn and winter. Reduce watering and feeding until warmer temperatures initiate new growth in spring. See indoor orchid cultivation
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.
