Poor Pruning Practices to Avoid

Using climbing spikes during pruning causes :

• Punctures to the cambium layer
• Permanent wounds
• Entry points for insects and disease

These injuries are not always immediately visible but can weaken the tree over time.

Climbing spikes are inappropriate for pruning and should only be used during tree removal.

Cutting large branches directly at the trunk or at key structural unions:

• Removes essential load-bearing elements
• Creates large wounds that are difficult to compartmentalize
• Can lead to internal decay
• Disrupts structural balance

Professional pruning instead prioritizes:

• Targeted reduction
• Redirection onto smaller-diameter branches (typically 3rd to 5th order)

This approach preserves structure while reducing mechanical stress.

Lion-tailing involves removing inner foliage and leaving weight concentrated at the ends of branches.

Consequences include:

• Increased lever effect
• Overloading at branch extremities
• Reduced structural resistance
• Higher risk of failure

While it may appear visually clean, this practice significantly weakens the tree.

Removing too many lower branches—typically more than 25–30%—can result in:

• Loss of overall stability
• Concentration of stress higher in the canopy
• Increased wind exposure

Crown raising must be gradual, justified, and adapted to the tree’s condition.

Pruning performed without proper assessment often leads to:

• Random or poorly placed cuts
• Lack of biological and structural logic
• Short-term visual results
• Underestimated long-term consequences

These approaches are typically driven by speed rather than quality or durability.

These methods remain common because they are:

• Quick to perform
• Visually convincing in the short term
• Less technically demanding
• Easier to sell to clients unfamiliar with arboriculture

They may produce immediate results, but they rarely reflect appropriate tree care practices.

Tree Cutting vs. Pruning

At AEC, we prioritize interventions based on the tree’s structure, mechanical constraints, and environment.

The goal is not to produce fast or uniform results, but to recommend cuts that are coherent with the tree’s condition and the objectives of the site.

Professional pruning is based on understanding—not speed.
