    Sounds like you have a case of bacterial rot going. Can you post a picture, please? It's hard to give advice unless I can see the problem. In the meantime, remove the plant from the medium and try soaking it in hydrogen peroxide (the stuff from the pharmacy--3% solution)

    Clean up the plant after removing the rot and repot in a fresh pot and fresh potting medium.

    cheers,

    It sounds like some of the pseudobulbs are rotting... you'll want to remove anything that's squishy, or the problem will just continue in the new pot. Make sure you carefully remove any squishy bulbs; keep only the ones that are firm. You can also use bleach if you don't have peroxide... soak the plant in a solution that's 1 part bleach to 9 parts water. It will not kill your plant... it will just kill the rot. After soaking your plant, give it a good rinse with lukewarm water. Then put it in its new pot with fresh potting mix. (If you are using the same pot, you need to make sure to clean the pot, too, so that no bacteria or fungus carries over).

    Good luck. And like the others said, pictures are a good thing... there's a lot of things you can see in a picture that can't be easily described with words.

    What's the minimum and maximum length of soaking time?

    10- 20 minutes should do it. Don't rinse the plant. And I would definitely toss the pot it was in. or scrub it out and bleach it with a very strong solution and let it air dry for a day or 2. In the hot sun.

    I have about 10 Oncidiums and all are doing well. I've killed several before discovering their secret.....mine anyway. Onc's need a lot of air movement. I have 2 oscillating fans going 24/7. One of our local orchid growers (more than 30 yrs. experience) has his fans going at such high speed it blows off his hat sometimes!!! He has no black spots on his. No air stagnation for the fungus to grow. Not sure what your watering practice is but mine prefer to dry out in between waterings. I hope this helps and Happy growing!
