In either case, you will want to trim each cane to have no more than 14 spurs. ‘Flame Seedless’, ‘Tokay’, and ‘Ribier’ are spur-pruned grapes. In spring, new growth will emerge from this old wood. Spur pruning leaves the bilateral cordons, or horizontal branches, permanently in place. One cane-pruning method is called the Four Arm Kniffen method and the University of Maine offers an excellent how-to video here. ‘Thompson Seedless’ and ‘Concord’ are cane-pruned grapes. New buds will emerge from these canes to produce leaves and fruit. This is because different grape varieties produce fruit on different bud spurs.Ĭane pruning leaves only the trunk and two to four shoots from the previous year’s growth to be trained along support wires. Grapes are either spur-pruned or cane-pruned. The variety of grapes being grown determines which of two pruning methods to use. Canes should not be not be cut during the growing season.

The main trunk should be ‘headed’ (trimmed) when it reaches the top trellis wire.
