Oncidium psychopsis not blooming

[Wendy]

I left the spike and just moved the plant. It bloomed normally on the next developing bud. Unless the spike turns brown and crispy never cut it. Sometimes Psychopsis will slow right down with flowering during the winter but it will pick up again when the weather warms up.

Thanks Ross...I'll try to keep that in mind

Where are you located (just to get me aclimated to your daylight regime?)

[mnh3281]

I am in Indiana, and they are facing in a north window, where they get bright, but indirect light. Most of my other Oncidiums are doing great and blooming well, so something I am doing this particular one isn't happy with, it's jut going to be a matter of what that "something" is.

Unfortunately, it will be a process of elimination but you will figure it out. Just don't rush it, the plant is healthy and you will notice enviromental changes within a few days. Keep us up to date on your progress it will help other oncidium lovers.

Well, I just did a deep scan on it to look for critters and saw nothing, but did find a new growth coming on it, which is good. Hopefully that is a sign of good things to come. I will take pictures and let you all see too.

I think the answer might be more light. I keep my Oncidiums in a south-facing bay window where they get full sunlight. I supplement the sunlight with CF lights. Once they start to spike, I move them back from the window a bit, but they still get 1200-1500 F.C. most days (about 2500-3000 next to window.)

Hmm, very intersting. I will try to do that. I just can't get over how picky this particular guy is. All my others look great, but boy this psychopsis is just a pain! I'll keep you all posted, as I see another bud potentially forming, so hopefully I'll get some results this time!

My Psychopsis gets high light as well. It is in a small grow room with three 400 watt HID lights. I know lots of people can grow and bloom them with less light but I never had much luck until I upped the light. My mistake with mine blasting was not paying attention when the inflorescence got long enough to be really close to the light...dried and fried buds. Just moving it a couple feet solved that problem.

Yeah... That's what makes me think this person needs to move the plant to a higher light window. I am north of Indiana by a bunch (kinda like Ontario latitude , but a North window is pretty dim for most plants (except some ferns) even on a sunny day. I am surprized by how much light even the "shade loving" orchids need when window-grown. My Phals take full sun (if it ever occurs!) with great gusto as do other shade-loving species. Now... In the summer, that's a different matter!
