late fall is best, prune that vine till it looks pathetic. if it is old it has a great root system to support it. so prune each sturdy branching about 3-4 feet from the trunk. leaving maybe 8 substantial branchings and then prune off all the small insignificant branchings down to where they sprouted from. in the spring you will have plenty of new growth and probably better fruit. pruning will not kill it and will cause you to have bigger better fruit in the spring.
