I never like to see roots twisted into a tight rootball. My advice would be pot it in fine bark only, in a pot no deeper than 4 inches, but 4 times the size/ area.
Of course my personal fave would be to shove it onto a mount tooty sweety, but I realise that's not to everyone's taste.
I would love to learn how to mount! In my former life, I was an evolutionary biologist and originally fell in love with orchids the first time I saw the Darwin Orchid on display at the Cleveland botanical garden show in 2009. And the epiphytes holding on to their life partners even more passionately than new lovers. Someday I hope to become this kind of matchmaker, but I am sort of floundering for now.
Bil - tooty sweety = toute de suite? I did not know you spoke my cultivar of franglais!
