@seaecho I agree with everything that drdawg/Ken has said; he grows a lot of staghorn ferns and he didn't mention it but he has a website where he sells plants (staghorns included) as well as wood mounts.
http://www.tropicalplantsandmo... I can vouch for his plants and products because I am a customer.
Last year I had a small Staghorn (P. bifurcatum) that was in a pot and it didn't seem to do much at all growth wise and just didn't look great so I decided to buy a mount from Ken to which I tied the little stag. It has attached to the wood and grown like crazy with new basal fronds ... it has almost totally covered the wood slab as you can see in the photo below that I just took. Please ignore all the dog hair in the picture; our golden retriever likes to lay on that sofa on the screened porch!
My eyes aren't the greatest but I'm wondering if perhaps your staghorn is being kept too wet? I think most Platycerium, including
Silver Elkhorn Fern (Platycerium veitchii) and
French Staghorn Fern (Platycerium veitchii 'Lemoinei') prefer to dry out between watering. I've read that the French Staghorn goes many months without water during droughts in it's native habitat of Australia.
