Pollarding is a method of pruning that keeps trees and shrubs smaller than they would naturally grow. It is normally started once a tree or shrub reaches the required height, and annual pollarding will restrict the plant to that height.

Pollarding is often used when the crown of an deciduous tree is simply too large for its location or when the tree has become unstable due to defects.

This method is often used to control growth of vigour trees such as willows.

In the past a similar type of pruning called coppicing as used to harvest wood for fuel in a sustainable way. Coppicing also provides ideally wildlife habitat for animals such as the dormouse and was once common practice in the making of charcoal.
