FORM & FUNCTION MEET WITH ESPALIER
Espalier Goals
Espalier (es-pal-YAY) is the training of a plant, usually a fruit plant, to an orderly, two-dimensional form. The word is derived from the Old French aspau, meaning a prop, and most espaliers must, in fact, be propped up with stakes or wires. This method of training and pruning plants had its formal beginnings in Europe in the 16th century, when fruit trees were trained on walls to take advantage of the strip of earth and extra warmth near those walls.

I finally gave up on Chester because winter cold would snuff out many of its canes down to ground level. If I remember correctly, surviving canes bore fruit that was too late in the season to ripen fully or in sufficient quantity.
