Dinema Polybulbon - What am I doing wrong?

[Miyuki]

This was supposed to be an easy orchid to grow and bloom. I bought it at a show a year ago. It was mounted on a piece of cork with a small amount of moss. Most of the roots were exposed, and it looked very healthy with bright green leaves and whitish-green roots. Initially I kept it placed in an open terrarium. Since then, most of it's leaves have turned yellow and dropped, and there is no sign of new growth. I took it out of the terrarium and I've tried every location I have to vary light and temperature, and I've re-mounted it with more spagnum. I was hoping some of you could respond by describing your growing methods for these little guys. Any thoughts would be appreciated!

well, after reading about your plant in Orchid Wiz, I've decided I must have one of these! really neat little plant!

This wants pretty high light (2000 to 3000 fc). It also has what looks like a rather distinctive winter rest..wants to be watered a lot while it's growing but then, in it's natural habitat, rainfall decreases to less than 1" per month until May. Humidity ranges from 70% to 85% in Summer and Autumn and then drops a little..

Hope this helps...keep us posted.
