Vertical shoot positioned (VSP) training is used primarily for upright-growing cultivators, especially those that benefit from improved exposure to sunlight that minimizes summer fruit rots and/or increases potential wine quality. As compared with Top Wire Cordon (TWC) training, VSP is much more labor-intensive due to the need for summer shoot positioning, leaf removal, and summer (top) hedging. VSP training employ a fruiting wire at 30-36", and usually three sets of catch wires at 10-12" intervals above the fruiting wire.
