Grapes require different pruning methods depending on the use of the fruit. Wine grapes are pruned more vigorously as it will yield lower yields but with more intense flavors. For both table and wine grapes, the fruit develops on annual reeds, so it is important to prune carefully and leave some of this year's growth for next year as well as last year's growth for this year's crop.
