Winter is a good time to prune your established grape vines. Grapes can be spur or cane pruned, depending on the variety. Cane pruning promotes the highest yield for most table grapes. Select a total of about 4 canes that come off close to the trunk and remove the rest (but not before you select your renewal canes). The canes that you are keeping should have at least 15 buds and be about pencil size. These canes will be your fruiting canes. Cut the fruiting cane back to about 15 buds and and remove any laterals. For every fruiting cane you keep, you should also keep one renewal spur. The renewal spurs will produce next years fruiting canes. The renewal spurs are short and should be cut back to about 2 buds. The other method of pruning grapes is spur pruning. Watch our video to learn more about spur and cane pruning. If you have newly planted grape vines, we have a great helpful article on how to train your new grape vines.
