Woofie, I also garden in Zone5. I have my vine potted in a hanging basket and bring it indoors in the fall when the temperature drops below 50 degrees. So far, that's worked quite well, even though the vine goes semi-dormant during the winter.
Gardener was the label imprinted on me when the souls were handed out and so be it. --Margaret Roach (Thank you, Sharon!) Notes from the Garden: Articles of interest on all aspects of gardening Cottage-in-the-Meadow Gardens: Come on in and take the tour! Check out the photos!
