Encyclia Radiata Ching Hua

[brownthumber]

I need help encouraging my Encyclia radiate ching hua to grow new roots. The existing roots look like they are shriveled and dying if not dead. The plant has been planted in a rooat with bark as it was when I bought it. I have seen online that these plants have done well mounted. Is that the best route to take or is there a way to encourage this plant to produce new root growth while planted? I really want this plant to live and could use all advice offered. I suppose it is worth mentioning that the green foliage and stem are extremely healthy looking.
