Tree Topping: Why It’s a Practice We Avoid

December 10, 2023

In the world of arboriculture, the controversial practice of tree topping has been a subject of debate for many years. While it may seem like a quick fix for managing tree height and size, the long-term consequences of this method far outweigh any perceived benefits. In this blog post, we will delve into the reasons why tree topping is considered a harmful practice and explore alternative, sustainable approaches to tree care.

Structural Damage:

One of the primary reasons why topping trees is frowned upon is the structural damage it inflicts on the tree. Topping involves cutting off the main branches and leads to the formation of weak, unstable limbs. These new shoots are more susceptible to diseases, pests, and harsh weather conditions, making the tree vulnerable to structural failure. Over time, the regrowth that occurs after topping tends to be poorly attached, leading to an increased risk of branch breakage.

Stress and Decay:

When a tree is topped, it undergoes significant stress. The removal of a large portion of its canopy disrupts the tree’s natural ability to produce food through photosynthesis. As a result, the tree redirects its energy to produce new shoots in an attempt to recover, often at the expense of the overall health of the tree. This stress weakens the tree and makes it more susceptible to diseases and decay.

Aesthetic Concerns:

Beyond the negative impact on the tree’s health, topping also has aesthetic consequences. Topped trees often develop an unsightly appearance with numerous, rapidly growing sprouts that create an unnatural and uneven canopy. This not only diminishes the visual appeal of the tree but can also affect the overall aesthetics of the surrounding landscape.

Increased Maintenance:

Contrary to the misconception that topping reduces maintenance needs, it often leads to increased maintenance requirements. The rapid regrowth of shoots necessitates more frequent pruning, and the weakened structure may require additional support to prevent breakage. This results in higher long-term costs and more extensive efforts to maintain the health and appearance of the tree.

Environmental Impact:

Trees play a crucial role in the environment by providing oxygen, absorbing carbon dioxide, and supporting biodiversity. Topping disrupts this balance by reducing a tree’s ability to perform these vital functions. Additionally, the stress caused by topping makes the tree more susceptible to diseases, further impacting local ecosystems.

Topping your trees to save on cost of removal may do more harm than good and actually cost you more money in the long run. Before you fire your landscaper, don’t get topping confused with pollarding trees. Pollarding is a similar practice used on juvinile ornamental trees to maintain size, shape, and production. This practive is still used today but, should NOT be used on a large mature deciduous or coniferous tree.
