How to mount a Staghorn Fern ?

[jowben1]

I just purchased a Staghorn fern and it is in a 2-1/2" pot of bark, hanging on a wire/. I would like to mount it on a piece of wood, so as to look more natural. My question is, as the plant gets larger, how do you replace the moss, or other medium?Or do you not have to? Will the plant "attach itself" to the wood? I would guess as the moss rots away, the plant would become dependant upon fertilizer for it's nourishment. Any advice ??? Thanks
