Why Pruning Matters

Pruning is the single most important maintenance practice for the long-term health and safety of your trees. Done correctly, it improves structure, encourages healthy growth, removes hazardous deadwood, and enhances the appearance of your landscape.

Neglected trees develop weak branch attachments, overcrowded canopies that block light and airflow, and dead limbs that can fall without warning. Regular professional pruning addresses these issues before they become costly problems -- or safety hazards.

  • Promotes strong branch architecture and natural form
  • Reduces wind resistance and storm damage risk
  • Increases light penetration to your lawn and garden
  • Removes diseased or insect-infested wood before it spreads
  • Maintains clearance from buildings, power lines, and walkways

Types of Pruning We Offer

Every tree is different. Our ISA-certified arborists select the right pruning technique based on species, age, condition, and your goals.

Crown Thinning

Selective removal of interior branches to reduce canopy density, increase light penetration, and improve air circulation. Typically removes 15-25% of live crown. Best for mature trees that have become too dense.

Crown Raising

Removal of lower branches to increase clearance beneath the tree. Essential for pedestrian walkways, vehicle access, sight lines, and building clearance. Done gradually over multiple seasons for large trees.

Crown Reduction

Reduces the overall size of the canopy by cutting back branch tips to lateral branches. Used when a tree has outgrown its space or needs to be reduced to lessen load on compromised structure.

Deadwooding

Removal of dead, dying, and diseased branches from the canopy. This is the most fundamental pruning practice and is recommended for every tree on a regular cycle. Eliminates falling-limb hazards.

Formative Pruning

Structural pruning of young trees to establish a strong central leader and well-spaced scaffold branches. An investment in the first 5-10 years that prevents costly corrective work later in life.

Pollarding

A specialized technique where the tree is cut back to the same points each year, creating a compact form. Used for specific species in urban settings where strict size control is required. Must be maintained annually.

Seasonal Pruning Guidelines

The best time to prune depends on the species, the type of pruning, and the result you want to achieve. Here are the general guidelines our arborists follow:

  • Late winter / early spring: Ideal for most deciduous trees. The dormant season allows you to see the branch structure clearly and wounds close quickly once growth resumes
  • After bloom: Spring-flowering trees like cherry, magnolia, and dogwood should be pruned immediately after flowers fade to avoid cutting off next year's buds
  • Summer: Good for deadwood removal, corrective pruning, and reducing vigour in overly aggressive growers. Avoid heavy pruning in extreme heat
  • Fall: Generally avoided for most species, as decay organisms are most active and wounds heal slowly. Exception: hazardous branches that pose immediate risk
  • Evergreen conifers: Can be pruned year-round for deadwood. Light shaping is best in late spring after new growth has hardened
Proper pruning cut technique

Common Pruning Mistakes

Improper pruning causes more long-term damage than no pruning at all. Here are the mistakes we see most often -- and why they matter:

  • Over-pruning: Removing more than 25% of live crown in a single session stresses the tree, triggers excessive sucker growth, and weakens the root system. We follow the one-quarter rule
  • Topping: Cutting back large branches to stubs destroys the tree's natural form, creates decay entry points, and produces weak, hazardous regrowth. Topping is never appropriate for mature trees
  • Improper cuts: Flush cuts remove the branch collar and delay healing. Stub cuts leave dead wood that decays into the trunk. Proper cuts are made just outside the branch collar at the correct angle
  • Lion-tailing: Stripping interior growth and leaving foliage only at branch tips increases wind load at the end of long levers, raising the risk of branch failure
  • Wrong timing: Pruning susceptible species during active pathogen seasons (such as pruning oaks during oak wilt transmission period) can introduce fatal infections

Professional vs. DIY Pruning

Small ornamental pruning is fine for homeowners, but anything involving height, size, or structural decisions should be left to certified professionals.

DIY Pruning

  • Small ornamental shrubs and hedges
  • Dead twigs within reach from the ground
  • Annual pruning of fruit trees under 12 ft
  • Branches over 3 inches diameter
  • Any work requiring a ladder
  • Trees near power lines or structures

Professional Pruning

  • Large trees of any species or condition
  • Structural pruning and crown work
  • Trees near utilities or buildings
  • Disease diagnosis and treatment pruning
  • ISA-standard cuts and techniques
  • Full insurance and liability coverage
