Training System
Top Wire Cordon (TWC) Download Top Wire Cordon PDF

Top Wire Cordon is arguably the most efficient training system for grapes, especially for procumbent or downward growing cultivators, especially those not prone to late season fruit rots due to shading of the fruiting zone. Summer labor is much less than that required with Vertical Shoot Positioned (VSP) training as shoot positioning and leaf pulling are generally not required. Learn More
