spur, a viticultural term for a shortened grapevine cane. A spur is a stub formed by pruning the cane to between one and four nodes, usually two. Spurs are used to provide the next season’s fruiting shoots. Of all pruning systems, spur pruning is the most severe since over 90% of the previous year’s cane growth is removed. Spurs are also left on cane-pruned vines to augment replacement canes at next pruning.
