Help Yellow Leaves on Dend.

[AnnieDN]

Thanks, Bud. The plants have been in a southern facing window, though I pull them away and to one side for the fall and winter months to keep them from getting too much sun...they get bright light all day with some direct sunlight in the a.m. We're in zone 5.

Part of the culprit may be the potting medium...I was unable to find what I usually use and ended up with something I wasn't happy with. I've had some of these orchids for years with no issues, until now. These are the 3rd plants at risk since using that other medium. I did lose one already.

I've soaked them in water with some root hormone and have repotted in a better medium and I'm going to bag them and keep them out of direct light to see if they don't revive.

Glad to know that you think it's not bugs. Thanks so much for your quick reply and information!

Thanks leafmite, I was alarmed too as that's what's led me here. I've had leaves brown up and fall off before, but never this quickly or this oddly. I hadn't heard about the bag and rocks technique...most interesting.
