DORMANT PRUNING OF CORDONS THE FIRST TIME
(INITIAL LONG CANE PRUNING SYSTEM) In order to move the fruiting area of the vine slightly away from the cordon it is desirable to make the first dormant pruning cuts on the side shoots coming off the cordons (arms) at ten inches on the single wire trellis and six inches on the Geneva Double Curtain System. This will allow the cluster of grapes to be far enough away from the cordon for easy harvest of the grapes and improve air circulation. Shoots coming off the cordon at about a 45 degree angle are the ones preferred for forming the spur system.Shoots coming straight up or straight down should be removed if not needed.In subsequent years, the previous season's growth should be cut back to two tofour buds to keep the canopy from becoming too wide.
