All topiary trees need to be pruned annually because the tree would otherwise revert to its natural shape. An example of this is the espalier linden, which is originally a tree with a regularly branched crown. Sometimes it is possible that at a particular level no individual branch is satisfactory for training, and thus creating the right final picture. In that case, make a small nick in the wood with a knife. This interrupts the flow of sap, and the nutrition accumulates. This influences the formation of buds (and branches), allowing you to hide that blank wall from view.

Espalier trees are ideal for use in gardens with limited space. They create privacy. Espalier trees are trees which acquire their shape through binding and pruning for training and shape. Aids are used for this, such as a bamboo frame or an ironwork arch and binding wire. Espalier fruit is often grown against walls, along wire and as a freestanding topiary tree. A tree tunnel (berceau) is also a particular, authentic way of growing fruit. A combination of a pear cordon on the underside with vines as a second layer on top is often used in a berceau. Using the correct pruning method we can shape trees in the desired way. With espalier fruit it is important to choose the correct wood for a good harvest.
