This is Joan's image of her sick Catt! Please help her figure out what is wrong:
I think you should cut off all the browned leaves.
Is the root system healthy? I would unpot the plant and check it out....It looks like it is drying up because it can't absorb water.
My guess is fungus on a sick plant. The plant appears to have either been:
A. over - watered
B. Under - watered and allowed to dry out the PBs.
I would take a look at the roots and see if there are any viable roots left. If there are, then cut away the dead stuff, treat for fungus, and 'spag and bag' this cattleya and keep it in low light until it develops some healthy roots.
I've had trouble getting this plant to grow new roots and bloom for me.
I repotted it in Sept. and had been withholding water and misting occasionaly. Since its been 4 months since repotting in a clay pot in bark, perlite and charcoal I thought I could move it closer to the window here in NY and added epsom salt to the fertilizer. Did the epsom salt, 1 tsp per gallon , cause this do you think?
The fungus should be dead now because of the physan 20. Are there any I'll effects of using too much of it guys?
Using some root hormone if you have some and sphag in a bag wouldn't hurt. I think you need some kind of bag around it to keep it from drying in the low winter humidity. But make sure the extra humidity is not causing it to rot more. I should also mention sphag has some anti-fungal properties due to the phenol its contains as well as water retension, so it might be useful. And changing it to a new growing media like sphag may stimulate some growth as well.
I have a feeling that it was underwatered as you stated you have been 'withholding water'. I think it's difficult to overwater orchids in coarse bark but humidity is low where I am.
Withhold the feritilizing and salts at this point, untill new roots and growths appear, because the plant won't be using any of it
Thank you. I have not ever been successful with the sphag and bag method though.
BD, I just want everyone to know how very patient and helpful you've been getting this photo of my sick orchid to this site. You are exceptional!!
I had a rootless cattleya one time because the media was rotted and not airy (oops) and therefore over watered...
I placed the whole plant into a container of water and eventually it was sending new growth and roots. I should have took it out and potted it in loose sphag at that point but I forgot and it died....(oops) It was a pretty white cattleya.
putting the plant in water acutally worked to get some roots and new growths...very strange method. I also used some hormone powder too
