    Default white fuzzy on catt roots media

    Hi everyone,
    I bought a new Catt yesterday and it looked as if it needed repotting because the media looked old and broken down. I started removing it from it's old pot to start cleaning it up, but I saw that much of the bark (actually most of it), had something white, fuzzy and stringy on it. It doesn't look like an insect at all...mealy bugs, for example...but more like some type of mold. What do you think this is? Should I be concerned or just continue to clean the roots up and finish repotting it?

    Default white fuzzy on catt roots media

    If the orchid is healthy I'd keep it and wouldn't disturb. Certain species develop fungus attached to the root system to simplify carbohydrates and potassium for the orchid. Its like a mutual relationship for the fungus and the host.

    This is kind of mold. Though it does not seem yo be harmful it usually precludes more important issues so be on the lookout! I've only seen it in tree bark. Roots look great. A good wash and new fresh media will do.

    I see it occasionally, only with organic mixes - and personally I would wash it off and repot in clean dry media.

    Hi Vicki,

    if your dirturbed about the looks of that mold you can wash the roots off and soak the plant in bucket with fungicide or spray with hydrogen peroxide then let it dry for a while before repotting it again with dry mix.

    If the plant were mine, I would first cut off any dead/dying roots. Then, I would let it soak in a solution of nine parts water, and one part bleach. I do not use store bought fungicides as I have found that some of them inhibit orchid growth...Just my opinion...Betty
