What is tree topping, and why is it discouraged?

Tree topping refers to the practice of cutting back large branches, often drastically, to reduce the height of a tree. This method is discouraged for several reasons.

Primarily, removing large branches can result in significant damage to the tree's structure and health. When large branches are removed, especially in a way that does not respect the tree's natural growth patterns, it creates large open wounds. These wounds become entry points for pathogens, pests, and could ultimately lead to decay, compromising the tree's overall integrity and longevity.

Additionally, tree topping can lead to a phenomenon known as "watts," where the tree responds to the severe cutting by producing numerous short, weak shoots that can grow rapidly. These growths are not only aesthetically unpleasing but also pose a risk as they are more susceptible to breaking in storms or under their own weight.

In contrast to the other options, which either do not pertain to tree topping or relate to different tree care practices, the rationale behind discouraging tree topping lies in its potential to harm the tree rather than promote its health or growth. Understanding the importance of proper pruning techniques is vital for maintaining the health and sustainability of trees in the urban landscape.
