At planting, one or two buds are retained near the graft union on grafted vines, or near the crown of the vine on own-rooted vines. Support is provided with a bamboo stake or other support. For grafted vines, the graft union should be planted above the ground so the scion variety does not produce roots. Where winter graft union protection is needed in order to prevent winter injury, it is critical that the graft union be planted close to the ground (1-2" above final ground level), with graft unions covered with soil or other insulating material during the winter months.

One cane is retained from the previous year's growth. This can be pruned and tied to the bottom wire, or a longer cane can be trained up to or on top (fruiting) wire if first years growth was vigorous. A second trunk can be started by leaving a short spur at the base of the vine, just above the graft union on grafted vines, or just above ground level on own-rooted vines. In Year Two, crop should be limited by cluster thinning or defruiting in order to encourage vegetative growth.

A single cane can be pruned and trained in each direction from the head of the vine (left side diagram), and cordon establishment can be initiated by retaining spurs on second year wood (right side of diagram). Spurs should be spaced about 6" apart. For highly fruitful varieties such as most French-American hybrids, spurs can be pruned to two to three buds. For Vitis labruscana species such as 'Concord' where basal buds (nodes one to three on one year canes) tend to be less fruitful, vines are short cane (long spur) pruned to five to eight buds. Shoots emerging below the top wire are removed unless they are needed for leaf area needed to develop the vine's reserves - generally speaking, a minimum of three shoots per foot of row should be retained. As shoot growth progresses during the season, shoot positioning is generally not needed but vigorous shoots that grow over neighboring vines should be positioned downward so as not to interfere with sunlight exposure of the neighboring vine. Third year vines should yield between one-half and a full crop, depending on the amount of trellis fill achieved. Vines that achieve full trellis fill can be fully cropped (as appropriate for the variety and desired wine quality attributes), while weaker vines may require some fruit removal by cluster thinning so that vines are not over-cropped.

Canes or cordons should be fully established and annual growth should fill the available trellis space. Depending on the variety, wine quality may be improved by reducing crop load, usually by removing second and/or third clusters on developing shoots. In regions where winter injury to trunks is anticipated, new trunks can be trained by retaining one or more suckers annually, and used to replace older, winter-injured trunks.
