Espalier made easy
Espalier, pronounced either “es-pah-lee-er” or “es-pah-lee-ay,” depending on how French you want to sound, is the art of training plants to grow against a wall in desired shapes.
In a formal setting, climbing plants are often made to follow geometric pathways. In an informal backyard, vines may be attached at somewhat more random locations and allowed to follow their natural inclinations in between.
The process can take years, depending on how quickly the plant grows. (Espaliered trees are often managed for decades.) Typically, you will need to spend an hour or so two or three times a year trimming away wayward stems and shoots and encouraging the plant in the directions that please you.
