fruit wall

Wall fruit refers to fruit grown on trees that are trained to grow flat against a support, such as a wall or trellis. This horticultural technique, known as espalier, was developed in Europe to help fruit trees thrive in less favorable climates.12

The use of a wall provides both support for the tree and essential heat, which is particularly beneficial for fruit production. Espalier can be used for decorative purposes or to save space, with trees trained on various structures including metal frames, wires, wooden trellises, fences, or walls made of stone, brick, or glass. Common plants suitable for espalier include dwarf apple and pear trees, as well as evergreens like loquat, fire thorn, and yew.2
