If you are still trying to get it out of the pot, first, I would shatter the pot. I have done this a number of times, and have no problems sacrificing a clay pot. The plant is what I value, not the pot. Once it is in pieces, I gently pry any clinging roots by taking an unused tag and gently working it between the root and the pot. Eventually the velamin will release, but be especially careful around the root tips since they are easily damaged. I notice they get less damage, and tend to release easier if they are NOT wet. After getting it out of the pot, I carefully / gently work the roots between the slats of a wooden basket. I prefer hanging baskets since they drain easier, and seem ideal for most of my vandas.
