When should I buy/plant a grape vine?

In theory the answer is 'any time'. However, there's little point in
planting things in January when the soil is cold and wet and they
either won't get started or might rot off in wet earth. Now is fine.
The soil is still warm and it can get its feet down and get settled in
before winter, thus getting a good start on next spring. In the
unlikely event of a dry spell, keep it watered but don't waterlog it,
either. It needs full sun on a warm wall if it's outside and good
drainage, too.
