Espalier is the ancient practice of training a woody plant to grow flat against a wall, fence, trellis, or railing. Partly decorative, but also to conserve space and, in the case of a fruit tree, to make the fruit more accessible for harvesting.

Lindsey Jones, one of our volunteers and a Certified Aesthetic Pruner, recently pruned our apple tree to reveal its unique structure and to let in more light to encourage better fruit production. The transformation was captured in before and after photos:
