Wrapping permanent cordon arms tightly around the cordon wire negatively impacts vine performance

Abstract

In certain winegrowing regions, it is a common practice to wrap canes very tightly around the cordon wire during the establishment of permanent cordon arms. This method of training may result in a constriction of the vascular system, leading to numerous deleterious impacts on vine growth, production, and longevity. This article summarises some of the key findings of previously published research regarding the use of this training method in South Australian vineyards.
