Pruning and Training Grapevines

(book excerpts)

Profitable grape production requires that grapevines be managed so that a large crop of high-quality fruit is produced each year. Grapevines must be pruned and trained annually to achieve this goal. The term dormant pruning refers to the annual removal of wood during the vine’s dormant period. Grapevines are pruned primarily to regulate the crop but also to maintain a vine conformation consistent with the desired training system. Pruning is one of the most important cultural operations carried out in the vineyard and, following harvesting is the most expensive and labor consuming. Training positions the fruit-bearing wood and other vine parts on a trellis or other support so as to shape the vine. The basic goal of training is to maximize production, facilitate vine management (i.e., spraying, tillage, pruning, harvesting), improve canopy microclimate and to support the mechanical load of the vine.
