This espalier consists of a single cord that is guided upwards in waves.
Features:
1 framework branch
framework branch is guided upwards in a wave-like manner
fruit wood is grown close to the framework branch
The wavy shape naturally restricts the flow of sap. Benefits of this:
Growth at the top is suppressed.
Vegetative growth (leaf and shoot formation) and generative growth (formation of flower buds and fruits) are evenly distributed along the framework branch.
This espalier shape is similar to the Zigzag Cord, which has right-angled bends.
