What is one of the uses of pollarding in tree care?

Pollarding is a tree care practice that involves removing the upper branches of a tree to encourage a specific growth form. One of its primary uses is to maintain a specified size of the tree. By regularly cutting back the branches to a particular height, arborists can keep trees manageable in urban environments, where space may be limited. This practice also helps to create a healthier structure by forcing new growth to develop from the cut stubs, leading to a denser canopy while still allowing for aesthetic and functional benefits.

While the other options related to growth, root development, and flowering might occur as a secondary effect, maintaining a specific size is the most direct objective of pollarding. Regular pollarding can also help enhance light penetration and air circulation within the tree canopy, contributing to the overall health and longevity of the tree in a controlled environment.
