I got this orchid at one of the Denver Orchid Society's meetings about 2 years ago. At first it seemed to do well and had blooms quite often. For about the past year it seems to be at a standstill. There is a lot of new growth which takes forever but it has stopped blooming. It does have quite a few air roots, it potted in large bark and because I live in a super dry climate its watered about 2 X a week and I feed with Miracle Grow Plant Food 2 X a month. Does anyone have any tips on growing this orchid that I could use? If I have posted in the wrong forum please let me know, I seem to do that a lot! Oh, its in bright light right now, the leaves are dark green.
