Question: 1 / 400

What does the term "topping" refer to in arboriculture?

Cutting off the crown of a tree

Topping refers to the practice of cutting off the crown of a tree, which significantly reduces the height and canopy of the tree by cutting back the main branches. This technique can lead to several negative consequences, including stress to the tree, increased susceptibility to pests and diseases, and the promotion of weakly attached regrowth. Topping is generally discouraged in arboriculture, as it can compromise the health and structural integrity of the tree.

In contrast, applying fertilizer to the roots, shaping the canopy through selective pruning, or injecting liquid fertilizer into the soil do not pertain to topping. These practices focus on enhancing the growth, health, and aesthetics of trees without the drastic measures involved in topping.
