    Default Dendrobium orchid

    My son brought home an orchid from school. Upon inspection when repotting I noticed the roots were extremely wet and some turning black, some are also kind of mushy. What can I do to make sure I can save it. I am brand new to orchids and have been reading many different things. Please help

    Thanks
    Jennifer

    Welcome Jennifer. Cut off all those black and mushy roots. Apply cinnamon powder or a fungicide to what's left of the roots and repot. I normally don't water until I see the first signs of new roots. Hope you manage to save the plant.

    Oh, cinnamon is hard on roots, not the best choice. It is good used on the plant part. It is a good fungicide and is often used when leaves are cut because of infection.

    What medium is your plant in? Sphagnum moss? Any idea what kind of orchid?

    In any case, it would be a good idea to pull it from the pot and gently remove the media and let it dry out. Do cut off any black nasty roots and you can use a fungicide on it. It can sit out of the pot for a few days (even dry) while you figure out what kind of orchid it is (can you post a picture?) and get the right kind of media for it and probably a proper pot too, depending on what it's potted in. Don't be too hasty with the potting, gather information, and your result should be better.
