Corkscrew Orchid help!

[Vonnie]

I also posted this in my intro thread, but I guess this is the better place for it.

The tag says it's trichopilia tortilis x trichopilia coccinea. I'm having a difficult time finding more info about it.



One of the leaf edges started yellowing and the smallest pseudobulb died. I'm trying my best to keep it from withering away. One thing I'm really concerned about is that it looks like it's planted in soil and has been for a long time. I don't know if I need to repot it. Please help!
