I would like more information on this type of orchid also... I've had mine for a few years and it hasn't reflowered for me
yet. A local nursery advised me to report in a mixture of soil, bark and moss. I find it takes forever to dry out after watering so it only gets watered about every 3 weeks. I use a moisture meter to tell when it is approaching the low end of moist before watering any more. I fertilize each time I water since it is so infrequent. Another thing, I didn't realize that the bulbs were an important part of the olant and removed the ones that didn't have "grass" growing from them. Later, I read that plant energy is stored in these bulbs. I basically know nothing about these orchids but thought I would share my experiences for other to comment on and or us both to learn from...
