Coelogyne barbata Lindl. ex Griff.

[RoseSD]

The problem is the oldest one is in the middle....If I cut it out it will leave just the single newst one left.
Unless.you meant cutting it out above the rhizome.leaving a big opened wound.facing up?

I just was out looking at my plants... I see Coelogynes with brown (rotten looking) p-bulbs in the middle of good ones. I think you can safely pot it back up... roots look good, so it's likely doing what comes naturally and not spreading into the new growth

Don't cut. I think that both of the browning p-bulbs are just reacting to having been divided. Roots look good, pot it back up. And leave off the sphag

You were right about Coelogynes' "going soft" tendency. They are so strange!
Orchids are cool.

Are you giving yours a lot of light or more shade? I read from a source "Coelogyne barbata loves bright sunlight and is able to tolerate direct sunlight (50000-70000 lux),", yet, on Andy's page he said it needs "Shade to Bright; 1500-2500 Footcandles (indirect light,pronounced shadowing)". Very confusing.

[Roberta]

I grow Coelogyne fairly shady. Bright shade or filtered sun is how I would describe it.

I don't know what location would have "direct sunlight" moderate enough...maybe Newfoundland... About the only orchids that would get direct sunlight around here would be things like L. anceps. I give a little shading even to Cymbidiums! Sanity-check your "sources"!

I did a quick conversion (Google "lux to foot candles" and you find a nifty converter) , 50000 lux is 4645 foot-candles. Still too bright for Coelogynes, more like Cymbidium or Vanda light. But in southern California where we live, "full sun" is about 10,000 ft-candles. So whoever came up with that "full sun" bit is starting from a much lower level than we have, and that's still too much.

I've not grown this species but I would use a potting mix with larger particles for more air at the roots. What do others think?

[Roberta]

I would use medium bark - yes, air around the roots is vital. This is still a fairly small plant, so a pot is appropriate - and roots look good. but larger Coelogyne plants do better for me in hanging baskets (net pots), usually with spaghnum, long fiber and loosely packed. So they get moisture, but lots of air. (A "formula" that I use for a lot of orchids - the "Andy" approach) But that's under my conditions - mostly outdoor growing, frequent water, also with lots of air movement so that there is also a tendency to dry quickly, They need moisture, but the "air" part is really important too,

I am a little worried. Since the unpotting the spike has turned brown as such. Is this going to get worse?

[Roberta]

Looks like the spike will not bloom. Disturbing the plant while in spike was not a good idea. Sometimes (often) it is best to wait and observe rather than rushing to change things on a new plant, especially if in spike. The leaves look good, Plant is probably OK. So wait until next year...
