I did it! I mounted my Tolumnia Pink Panther and it looks adorable
When removed from the pot, the roots were in pretty good shape. I did drill some additional drainage holes through the mount to ensure there would be no sitting water in the wood grove. I think there could be some room for a friend or two.
I also mounted my Aerangis Citrata. It came in sphagnum and I knew that would be problematic. Sure enough there were some rooted roots, but not too many. I'm glad my extra keep-it-dry- vigilance paid off.
