Staghorn Ferns

I love Staghorn Ferns. Today I mounted four onto a wormy board from the salvage store that I cut with my miter saw. Then I put a picture hanger on the back of each board and hammered some nails to the front in a circular pattern. The ferns don't need much soil, and you wrap the roots with some sheet moss. I made a spiderweb of twine (first I used copper wire but it's poison to plans apparently, so don't do that) to hold it in place, and voila! You need to take it down and soak it well. And whatever you do, don't try and wipe the dusty looking layer off of the leaves, the plant needs that layer. Now where will I hang one on my newly painted walls? And who will I give the others to?
