Default Cattleya iricolor help!

Hi, I bought my first two Cattlyas a month ago, C. walkeriana and C. iricolor. I have both on a South facing windowsill, potted in a mix of large bark pieces and sphagnum moss. The walkeriana has immediately put out two new roots and (I think) a new leaf. However, the iricolor looks as emaciated as when I got it it. The bulbs are shrivelled, the leaves themselves kinda "dimpled" (I'm sure there's a botanical word for this) and I'm.lost about what to do. Does it need more water, less water? How can I get these bulbs to fatten up?

Thanks in advance for any help.or tips.

How did the roots look on the iricolor?

I can't recall. I guess I should have checked but I've not been buying orchids long enough to have thought about this! I will now, thanks.

Definitely check the roots.

Those are pretty classis desiccation symptoms, but that can be due to insufficient watering or a root system that is unable to take water up.

Thanks Ray, will do. The potting medium is kinda damp, the moss is still wet after a few weeks. Is it retrievable, and what should I look for with the roots?

If the roots are rotted, you'll know.

Rescue comes in the form to two aspects: getting the plant to grow new roots and preventing it from further desiccation while it does.

My number one suggestion is to acquire some Kelpak, mix up a solution (8-10ml/L) and immerse the entire unpotted plant in it for a few hours. (If you cannot get that, a liquid rooting hormone will work, but you'll have to rely on others for the concentration to use.)

Pot it up in a substrate with which you have experience and plan to use going forward. Moisture-holding but airy is the preference.

Water it in with the Kelpak solution and invert a clear plastic bag over the plant and pot, leaving the bottom open. That'll help maximize the humidity around the plant without becoming stagnant.

Place it in a very warm, shady location, and in a few weeks, new roots should emerge. Once they have penetrated the substrate, you can likely move it back to normal care.
