I have a wonderfully huge lotus vine growing in my yard (zone 6b) and I would love to bring it in my unheated garage, that rarely freezes, and store it dorment for the winter. I am thinking of placing it atop the upright deep freezer to give it a little extra warm. Do any of you think this will work, can I create a zone 9 winter with this approach? How much water should I give it? Will it need light? any ideas would be much appreciated.
