As one of those who doesn't like cork....I have a very hard time getting the roots to attach to the cork, and they dry out way too fast for me. I've lost probably a half dozen orchids that I tried mounting to cork. I even gave away the pieces I had and swore NO MORE!
That being said, as I've learned in the interim, it was probably MY error in not watering them often enough. Now that I'm a little more knowledgeable, I would consider trying again...though my newest 'thing' is potting them in hanging wire baskets (the kind you get at Dollar Tree for a buck, with the cocofiber liners.) as I tried a few of those last year and the orchids are VERY HAPPY!
Elaine has suggested mounting horizontally instead of vertically, and I have not tried that.
