Send it to me, I'll take care of it.
Seriously, though, I'd recommend unmounting it. I don't have this one but I grow some related species and they're easier in pots or baskets than on mounts, especially if you don't want to water every day.
Since this one is a rambler and likes a lot of moisture, a broad, shallow plastic pot ought to suit it well. Get a sturdy plastic plant saucer at your local garden or big box store, drill some holes for drainage, more holes around the rim if you want to hang it, and fill with a medium that suits your watering style. Sphagnum over styrofoam peanuts works well, but CHC or bark mixes are also okay with more frequent watering.
Good luck!
