Hi everyone, I just bought a few mail order kiwi vines that were all listed as being hardy to zone 4. after doing some internet research most of the others seem to be true to the zone 4 rating except the ken's red which little zone info can be found.Has anyone had any experience with this particular cultivar in the cooler zones? I live in south eastern New Brunswick rated at USDA zone 5a, any info would be greatly appreciated.
