    Default Soggy Cattleyas- to repot or not?


    I have 4 rather newly purchased cattleya orchids from a local greenhouse. I've repotted two of them, because they were packed in soggy moss and cattleyas are more happy with air circulation in their roots. When I repotted the both of them, almost all of their roots were rotten and dead (squishy, outer covering came off easily). Basically both pots were filled with rot. They did have some viable roots, and they are now in new mixtures (one is bark/perlite/charcoal, one is coco husk/bark/perlite... kind of an experiment to see which works better for me).

    Now, I've been wondering if I should do the same immediately for the other two. They are in the same moss from the same greenhouse, so likely have the same root situation. However, none of the catts have new growths yet. I've heard that it's best to wait until they have new growths/roots beginning, so they can hold on to the new potting mix.

    Should I wait until the other two cattleyas have new roots/growths? Or should I repot them immediately, assuming that their roots are rotting like the others?

    I should probably mention too that they are all reasonably healthy-looking, my only cause for concern is what the roots probably look like.

    Any advice would be appreciated.

    You have done the correct thing when you repotted the first 2. IF I were you I would repot the other 2 as well. Both your experimental grow media sounds good to me.

    Under ideal circumstances it's best to repot cattleyas when you see new roots and new growth but your situation sounds more like an emergency repot. I would definitely repot the others that are in moss.

    Just remove all the squishy roots as near to the rhizome as possible repot in your new compost and they will be OK. Just to add to this discussion new roots will only grow on newly produced pseudobulbs. Some species develop the bulb before the roots and vice-versa. My question is do
    the old roots from the old pseudobulbs die off and the new growth use the old bulbs by way of the rhizome??
