    well time for more drastic will have to remove any diseased tissue. I use a sharp knife or mat knife to do that. Cut back to good looking tissue, brush 10% bleach solution on area....let dry, then coat cut with powered cinnamon...keep water off the leaves and cut.

    Hope this works

    Hi Oksana,

    I have quite a few cymbidiums and I have seen this problem before. A plant appears to be healthy but some new/young growths just rot out and are easily pulled out.
    There are times when the plan has several new growths but only one rots out.

    The thing with cymbidiums is that they do not like high humidity and water sitting in the crown when it is still growing.
    They like their roots moist and they want heavy watering. But for some reason if the humidity around their leaves is too high or the crown stays wet for too long the young shoots fall prey to bacterial infection.
    Mature leaves seem to be unaffected but any new leaves emerging from the crown is vulnerable.

    I had a high rate of these rots when the cymbidiums where inside the greenhouse. After I moved them outside under shade, I rarely find these problems anymore.

    For the crown that is already affected by rot, you can use a peroxide solution as others have stated.
    To prevent this from happening in the first place, try to keep air circulation high to make sure any water/condensation in the crown evaporates quickly.
