Winegrape vineyards can be converted for machine pruning without replanting

Mechanical pruning reduced labor costs by 90%, resulted in increased grape yields and berry quality was as good or better than hand-pruned vines.

Wine grape growers in the San Joaquin Valley who want to switch from hand pruning to mechanical pruning won't have to replant their vineyards to accommodate machinery, according to a new study published in HortTechnology by University of California Cooperative Extension researchers. Instead, growers can retrain the vines to make the transition, without losing fruit yield or quality.
