Why Calgary Homeowners Should Avoid Topping Trees

What Is Tree Topping?

Tree topping is the indiscriminate cutting of large branches or the entire crown of a tree to reduce height or perceived risk. Unfortunately, it remains a common practice in some areas, despite being universally condemned by arborists. Topping causes long-term harm and usually costs more than proper pruning.

Why Homeowners Try Topping

Many people request topping because they fear a tall tree might fall, or they want to improve sunlight access for gardens or solar panels. While the instinct is understandable, topping doesn’t solve these issues. Instead, it weakens the tree and creates future hazards.

The Damage Topping Causes

·       Removes too much leaf area, starving the tree of energy

·       Creates large wounds that invite decay and pests

·       Stimulates weak, fast-growing shoots prone to breakage

·       Increases storm damage risk rather than reducing it

Alternatives to Topping

Proper pruning reduces risk without sacrificing tree health. Crown thinning, reduction cuts, and structural pruning improve light penetration, balance canopy weight, and lower wind resistance. In some cases, strategic removals and replacements may be the better option for long-term safety and aesthetics.

Calgary-Specific Risks

Topped trees in Calgary are especially vulnerable. Harsh winters cause dieback in exposed shoots, while chinook winds snap the weak regrowth. The result is an unsightly, hazardous tree that often requires removal years earlier than necessary.

Final Thought

Topping is not tree care—it’s tree damage. By working with an ISA Certified Arborist, Calgary homeowners can achieve safety and sunlight goals while preserving strong, beautiful trees.
