Tree Pruning

Tree pruning is a technical intervention aimed at improving a tree’s structure, stability, safety, and overall health.

Unlike arbitrary cutting, professional pruning is based on:

• structural analysis of the tree
• understanding of tree biology
• evaluation of mechanical stress
• adaptation to the urban environment, site conditions, and actual use of the space

The objective is to perform targeted interventions that reduce risk while preserving the integrity of the tree.

Pruning may be recommended to:

• reduce weight on specific branches
• correct structural defects
• improve overall stability
• provide clearance from buildings, walkways, or infrastructure
• remove deadwood or hazardous branches

Each intervention must be adapted to the tree’s actual condition, not applied uniformly.

End-Weight Reduction

Reducing load at the extremities to decrease mechanical stress and limit the risk of failure.

Structural Pruning

Interventions aimed at developing or correcting structure, particularly in young or semi-mature trees.

Crown Thinning

Selective reduction of foliage density to improve balance and distribute loads more evenly.

Clearance Pruning

Adapting the tree to its environment, particularly near buildings, traffic areas, or infrastructure.

Pruning may be recommended when:

• branches become too long or too heavy
• the tree shows structural imbalance
• conflicts with structures are present
• signs of weakness are observed
• previous improper maintenance has altered the structure

The timing of the intervention always depends on the objectives, species, tree condition, and site context.

Certain interventions can be harmful to trees:

• topping
• removal of major structural branches
• excessive cutting
• interventions performed without proper structural assessment

Tree Cutting vs. Pruning (Québec terminology)

At AEC, we prioritize:

• structural reading of the tree
• precise branch selection
• reduction and redirection rather than excessive removal
• interventions adapted to each specific situation

The objective is to achieve a durable, safe result that remains consistent with the tree’s natural structure, environment, and real constraints.

In Gatineau and Ottawa, trees often grow in constrained environments:

• proximity to buildings
• restricted access
• built environments
• limited or compacted soils

Our interventions are adapted to these realities to ensure safe, precise, and context-appropriate execution.
