How long has it been in the ground? If it has been growing for a few years, it would be best to wait until early spring next year. However, the vine can be transplanted now with some extra TLC. When digging up the vine, take care to get as much of the root system as possible. It would be better to water some first rather than digging up a dry plant. This will help the soil stay with the roots. Be sure the hole in the new spot is both deep and wide enough. Once planted, pack in the soil around the roots, water well and mulch. The transplanted vine will need extra water through the summer to get it established.
