I cut my corkscrew vine back to get it inside for the winter and just stick some of the cut vines in water and set them on a seed mat. I have better results with the older mature vines. The new soft growth doesn't root well for me. I use an aerator in the container of water. If you don't, make sure you change the water every couple days and wash the inside of the container weekly.
