Spotting on coelogyne rochussenii normal?
 

Hello
Is spotting on coelogyne rochussenii leaves normal when flowering and in spike? The bulbs are healthy and as are the roots. The leaves are much more green than in the photos.
I got is as a kind gift from a vendor and just want to make sure its a characterstic of the genus. Not questioning a grower just for my own sake.
Thanks!

Thin-leaved plants tend to get spotting. Probably bacterial or fungal, not harmful. Eventually old leaves drop, new growth develops. The main thing is that you want to stay on the lookout for spidermites, which tend to afflict all of the thin-leaved genera. As long as you don't have those, I don't think that there is a problem. (They especially like dry conditions... so if humidity is low, be especially vigilant.)

Thanks Roberta!
Is it worth treating the leaves with anything? Just as a precaution

I'm not inclined to treat until I know what I am treating. It would do no harm to spray the undersides of the leaves with soapy water, or maybe neem oil in soapy water if it makes you feel better, but certainly nothing stronger than that.

Thanks Roberta.
I will do that just to be safe. If the bulbs and roots were in bad state - I'd be more concerned. But honestly, they look so beefy & healthy so it just makes me think the got water on the leaves or too much sun. The blooms don't show any virus symptoms to me either. AND there is a new growth coming in. Whew so much to tell.

The plant was gifted to me from an orchid nursery vendor, so I'd hate to think he gave a problematic plant when it would be so visible on the leaves. I don't have much experience with coelogyne orchids, so I do not know any better - hence my inquiry to the forum! I appreciate your help.

Love these coelogynes but mine also get spotty. Seems to be their thing. I've a humidifier in the same room so spider mites have not bothered them(or me)yet. When the vandas go in the shower for a drink, I've put these in as well along with the stanhopeas. Phew!

Oh! I should amp up my humidifier. Are your spots due to lack of humidity?

A vendor at the Tamiami show told me this is less tolerant of drying out than most Coelogynes. He grew his in wet sphagnum and recommend customers do the same.

Thanks ES, I will take this information into consideration as I care for this orchid going forward. It is in flower now, and my goodness, it smells DIVINE!

They are amazing in flower.
