Hi all,
I just mounted a small staghorn fern on a piece of wood, and it was doing well for a bit, but now it seems to be permanently droopy- Even after watering it by immersing it in water as instructed.

I have a very big staghorn that is in a pot that I've had for years, so I'm pretty familiar with care, but this one has me stumped. The odd thing is, it has some new growth emerging.
What did I do wrong?
Thanks for any help you can give me.. I'd really hate to lose this beauty.
