Select one cane every 1 to 2 ft. on either side of the cordon to use for fruiting. Also, select 1 to 2 canes for every two retained fruiting canes to use as replacement spurs; cut these canes to two buds long. Alternatively, leave two adjacent canes in one direction and then two adjacent spurs in the other direction, alternating down the cordon (see diagram to right). Cut the fruiting canes to about 2-3 ft. long and remove all other canes. Tie down the fruiting canes outward, away from the cordon. Some canes may need to be pulled over to the other side from where they grow naturally. All canes and replacement spurs should originate from near the cordon. Repeat this process each winter. Don’t use too many canes and don’t allow the cordon to grow too long or the large number of clusters will stunt the vine.
