Deborah. That's really interesting! Personally I would transition it gradually by planting it in a pot in damp vermiculite, perlite, or other medium and encasing the whole thing in a clear plastic bag. Make sure the leaves are not touching the sides. I would keep it where you rooted it since it seems to do well there. If it seems to be holding up OK after a few days start opening the plastic bag a little more each day until it seems able to manage without it. Then you can either keep it potted or plant it in the garden, whatever your original intention.
