Oncidium Leaf Pleating

[Becca]

So I was just reading another post where someone mentioned that the leaf of an oncidium in a picture posted was pleated. I soon recognized the pleating, as I had never seen or heard of it before and just realized my plant I had was just growing fast and hadn't had time to straighten itself out yet....hehehe. But on the serious side, I have two growths on my oncidium and it even bloomed for me late last year (it is an Winter Wonderland "White Fairy") and only one of the growths has the pleating problem with it. I am 99% the roots are all rotted on it, but under the new growths are many new roots. I just can't bring myself to cut off all of it's other roots...I just can't do it! I feel like I will be killing my plant. Is there any hope my plant will survive with the new roots? I have a humidity tray and I keep it in a bright window and the growths are doing great, although the psuedobulbs are shriveled. If I replant my oncidium in s/h medium, is there any chance it may survive? I have heard of people being able to bring back there plants using this growing method.
