How about placing the entire mount inside the pot, treating the mounting branch as part of the potting medium?
You may need to cut the bottom part of the branch so that it sits at the proper level inside the pot.

Just an idea.

I assume that by asking this you know that it will accept being potted? Some plants don't readily accept being potted if they prefer being mounted. I know nothing about the plant in question, but felt that I should point that out. Also since you ask about what to pot it in, I hope that you have researched enough to know what type of media will be acceptable to this plant for potting. Not every plant will accept every type of media. For example, I use sphag, s/h, and bark mixes, depending upon the plant. One ang is 'potted' in loose crumbled tree fern in a clay pot, in a tray of water. The roots immediately died if I did anything more 'potted'.

How tightly attached are the roots to the mount? If tightly attached, then wetfeet is right on, with mounting it. But if the plant is just tied to the mount, and no roots are actually attached to the wood, then you can just cut the lines, and pot it in whatever is the appropriate media for it's roots and your watering habits.

I could not find any hits by searching the internet for "Tuberolabium odorotissimum", perhaps that is a typo and supposed to be " Tuberolabium odoratissimum"

Most of the plants I saw were mounted on branches or cork. The few that are "potted" appear to just be sitting on top of sphagnum moss in a pot.

cbary may be right, that orchid might prefer to stay mounted.

If I was you I'ld probably leave it mounted. If you really need to have it sitting on a shelf instead of hanging then just remove the hanger and stand the mount inside a clay pot without any other medium. When you water soak the pot as well and it'll help keep the humidity higher around the roots so you may get away with watering less often.

I have one of my small mounts in a clay pot that is lined on the bottom and sides with sphag. I soak the sphag heavily when I water to keep the mount surrounded by more moisture. I turn the mount away from the fan which helps keep the container and mount wetter.

I also have flourescents and I hang some of my mounts from the dangling chains on the end of the light. Even with the drastic drop off in light intensity at the end of the tube, I can hang the mount very close to the light and they do very well. Those mounts I do have to take down and spritz every day because the lights will dry them out quicker.

De mounting an orchid is generally easy. Soak the whole thing in a bucket of water for several hours or over night and the bulk of the roots will peal off with a minimum of tearing when growing on most materials. If it is on/in soft treefern you can crush the mount and untangle the roots from the sticks, if it is on hard treefern you are screwed. New-dry sand-blasted wood is tough to get roots off of too sometimes.

I would venture to say that more roots are damaged repotting an orcid than unmounting one in most cases.

I don't know this species very well but I would assume that there is a reason for it being mounted. Are you sure it would not resent being in a pot? I certainly wouldn't risk removing it from the branch. I have several orchids that I or others have moved from mounts to a pot - mainly to supply greater stability, NOT to supply extra water, which would be very dangerous. Look on the Gallery in a couple of days time and I will show a pic of one of them.
