golden-bow dendrobium · Dendrobium chrysotoxum
Also known as: fried egg orchid
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
