Espalier

I had the opportunity to visit a yard that had two espalier apple trees. Espalier is simply a method of training fruiting trees, like apples, to grow in a fan pattern along wires or along a fence. For example, a common espalier technique is to string 4 wires between two solid posts, plant an apple midway between the posts, and then train the branches to run along the wires. Since there are two branches per wire, a total of eight branches are trained along the wires and secured with loose-fitting, foam covered ties.

Espalier is a fabulous way to maximize yield in a small amount of space. Besides, it just looks really cool! The other great thing about espalier is that each leaf has much greater exposure to sunlight, which means that these little ‘solar panels’ are maximizing their output of photosynthates (fancy term for sugars etc.) to the tree’s fruit. Many lower, and interior, leaves on regular apple trees rarely receive full sunlight and therefore are unable to contribute much to fruit development. On the other hand with espalier, virtually every leaf is fully engaged in fruit production.

Espalier is not difficult to do, and great for those of us who love homegrown apples, but don’t have the room for a broad, 15 meter tall tree.

 And if nothing else, for me at least, just saying the word espalier makes me sound a whole lot more sophisticated than I am.
