Cymbidium ‘claret x vieux rose’ dropping green leaves!? Help!
 

Hoping I can get some insight on best courses of action!

This was given to me by an experienced grower about six months ago, and now I’m having this problem.
Below pics show how the green leaves appear to have rotted at the base? The “sheath” the leaves are growing out of appears to have turned brown first.

I have another cym. that had new growth do basically the same thing after growing about a foot tall. Ideas? The two plants were growing about eight feet away from each other with still healthy unaffected plants growing between them.

Sorry, but I think it's dead. When you got it, was it in that pot, or was it a bare older pseudobulb? Was it a single pseudobulb bulb sitting in the pot, or did it already have other growths? Did it have long, whole leaves when you got it, or were they already cut off above the pseudobulb?

Cymbidiums tend to rot like this when they get too hot and when their soil is too dense and wet. Need more information before answering more.

It had been divided from a larger whole before given to me. New potting media, etc.
It might have gotten too hot, I suppose.
More than one pseudo, though. Three or four, I think. I’d have to go double check. At least three, though.
It had plenty of full-growing leaves when it was given to me, and they were growing from at least two of the pbulbs, maybe three.

I don't think it is dead, by any means. I have had new growths rot, but usually there are others that are fine. I have particularly noticed the phenomenon on newly repotted plants... may happen when roots get damaged on a particular growth. In that case, just wait for the new ones. Perhaps back off watering a little, but don't let it go dry. Weather has improved, so that should help. As long as there are firm pseudobulbs, there's hope.

Thanks, that’s what I was wondering as well.
There are a couple bulbs that I think are dying as they seemed a bit soft, but I’ve got to check again. Would you think they should be cut away immediately if they’re getting soft? I think there’s still one more that’s doing well.

Even though it's the wrong time of year for repotting Cyms, I think it's worth taking it out of the pot to see what is going on. If there is rot, you'll want to cut it away before it spreads.

I will, thanks!

Sorry to say but your plant is a goner as I see no evidence of a viable green growth. This is most commonly called black rot and starts at the base of a green bulb, often the newest growth. Water held in the new growth can often instigate this problem. I have not heard of heat as the culprit.

It can spread to other plants, so if you are determined to keep it, keep it away from any other plants in your collection and let it dry out.

Yeah, thanks. I’m thinking it’s not going to make it. Already segregated.

Just for the future, if you catch this quickly enough and there are enough firm bulbs, you can often save the plant. It takes a keen eye, a lot of experience, a little luck and a good fungicide,

Thanks. Yes, I’m definitely making more of an effort to keep on top of this. And this cym was kind of in the back corner of a grouping, so I definitely neglected to look very closely at it til the bottom third of the leaves were all black😔
