I have a RECLAIMED wooden telephone pole that I put up in my yard last year. I would really love to plant a big wisteria vine at the base to make its way up the pole. The pole does not have any "hand holds" for the vine to grasp. Will the vine fall back down the pole because there aren't any horizontal supports?? I have seen this done with a trumpet vine and it looks amazing, but the trumpet vine has little rootlets to help it out. Any advice is helpful!
