I spotted a shelf of Platycerium at work today and ended up buying a couple small ones on my way out, most likely the most common ones. P. bifurcatum? They are potted up in something but from my understanding they are best grown mounted, which is how I would like to grow them regardless of whether they can be left potted or not. I've never mounted anything before but I do have a couple pieces of cork bark that should fit the plants nicely for a while. I was wondering what to use to secure them to the corkbark and what or if I should have anything under them, some sphagnum moss maybe? I saw one site recommending peat moss but I don't see how that will stay in place at all if it is to get wet.
