Finally.. something I know alittle about . I love mounted orchids, they are just easier for me to take care of. You can either mount them on cork or tree fern or wood slabs. My local nursery sold me some cabbage palm pieces. I have found that these work the best for me. About a week after I mounted acouple of my orchids on it they showed new root growth towards the wood. I used zip ties to keep mine in place, only because I didnt have any fishing line or string. I placed the orchid where I wanted it to establish itself, drilled holes on either side of the plant and zip tied it in place. Now when you look at the pics, you can see dead roots (I was lazy and didnt want to disturb it any more than I already had). but the pics should give you a general idea of what I did. Im sure there are better ways of doing this, and I would love to see how other people have their orchids mounted.
The first 2 pics are of my Enc. Tampensis and close up of new roots. The last 2 pics are of my Enc. Gay Rabbit and of course its new roots up close.
