I purchased this adult plant in February 2014. I put it in a well drained pot in very small mix of bark chips, gravel. Water it regularly once a week, with rain water, keep it moist. The little potted plant, sits in a large wide 8 inch high and 8 inch diameter glass cylinder without a top. There is plenty room for the plant to grow. Around the well ventilated small plastic pot, I have some sphagnum moss to keep the humidity up inside the glass cylinder. Fertilize once every 2 weeks with 1/4 strength 20-20-20. Flush with rainwater every other week. Keep it in a place with subdued light, plenty to read by. Yet the plant does not grow one iota since I got it, yet looks healthy. All my other orchid species thrive, why not this one? Any advice from those who have experience with this plant would be appreciated.
