    Catts are tough to recover. Doc Spock is one of our experts, but he's been busy lately so I don't know if he will chime in. I would remove the dead leaves, any dead roots. I would dampen the base of the plant, apply some powdered rooting hormone - this can help prevent damp-off - and place the plant in a clay pot with sphag. To entice roots at this point you have to offer some moisture. Check regularly (every other week) for root growth, when/if they start to develop, move to a bark mix when about 2" long.

    I think sphag in a bag fails because the the humidity in a bag is %100 which is too high for an orchid. I learned my lesson when I killed one in a closed bag. Always leave the bag somewhat open

    Since sphag in a bag never worked for you, I think you should do what Diane suggested and perhaps put a loose bag over it initially, while still allowing some airflow...the plant looks a little too wrinkly for normal humidity.

    Luckily good mericlones are readily available for sale at affordable prices. Best Wishes

    I had this happen to a young catt last summer...well...I had two of them, one lived and one died. But the problem was that the mix in the clay pot dried out really fast, but I didn't up my watering, and the plants completely dried out and had no roots. I put them in sphag (also using rooting hormone) and kept them moist, really paying more attention to not let them get bone dry like before. One survived...one didn't. The survivor is putting out tons of roots all over the pot now and I can treat it like all the others.

    Sometimes this is just how you learn. Because at that point these were my first catts and when I read "let them dry out between waterings" I took it to the extreme! Hehehe. But now I learned a lesson about that!

    How long should you let a catt dry out between waterings, if at all? I am starting a new adventure with 12 new catts of various sizes. They are arriving bare root packed in wet sphag.

    Katie, they want to dry out between waterings. But not be left dry for very long. Pot size will determine how often they should be watered. Smaller and clay pots will need it more frequently than larger or plastic pots.

    Joan, I'm with Diane. Cut the dead leaves off, dip the whole plant in Physan 20, applying some rooting compound, then pot in clay with sphag. As the moss dries out, rewater. Don't be in a rush to move it back to bark. Let it heal and grow some healthy new roots first.

    I had some trouble with a cat in Sept, and it responded wonderfully to that treatment. Sphag and bag is hard because the plant needs good air circulation. Set it on a pebble tray with water, so that the plant is sitting above the water level. That will really boost humidity.

    I agree with Julie and Diane on this one. Claypot and sphag is the way to go in order to rescue this catt. Sphag and bag is way to wet. The plant is dying because it probably has lost all roots and becoming dehydrated. So we have to regrow its roots.
    Cheers. Hoa.
