Avoid These Common Tree-Pruning Mistakes for a Healthier Landscape
- By the dedicated team of editors and writers at Newsletter Station.
Pruning plays a critical role in maintaining the long-term health, safety, and appearance of your trees. When done correctly, pruning promotes strong structure, supports new growth, and helps prevent disease. Unfortunately, many homeowners prune without proper technique or timing—leading to long-term damage rather than improvement.
To help protect your trees and keep your landscape thriving, here are the most common pruning mistakes and how to avoid them.
Over-Pruning or “Topping”
Removing excessive branches places stress on a tree, reducing its ability to produce energy through photosynthesis. Over-pruning can also cause weak, rapid regrowth called water sprouts, making the tree more vulnerable to storms and pests. Stick to removing dead, damaged, crossing, or hazardous branches, and aim to avoid removing more than 20–25% of live growth in a single season.
If you’re unsure, less is more.
Pruning at the Wrong Time
Timing matters. Most trees benefit from major pruning during dormancy—late winter to early spring—when the tree can heal before vigorous growth begins. Pruning during the active growing season can cause unnecessary sap loss, attract pests, and slow recovery.
Some trees have exceptions:
Maples & birches may “bleed” sap if pruned too early in spring.
Oaks should be pruned only during dormant months to reduce the risk of oak wilt.
Using Incorrect Cutting Techniques
Jagged or poorly placed cuts expose trees to infections and slow healing. Always cut just outside the branch collar, where the branch meets the trunk, to support natural sealing. Avoid both flush cuts (too close to the trunk) and long stubs that decay and invite disease.
Use sharp, sanitised tools and remove large branches with the three-cut method to prevent bark tearing.
Pruning Without Assessing Tree Health
If a tree is already stressed—showing fungal growth, dieback, pest damage, or nutrient deficiencies—pruning may worsen the issue. Address health problems first through soil improvement, watering adjustments, or pest treatment.
When in doubt, consult a certified arborist before cutting.
Ignoring Safety Precautions
Tree pruning can be hazardous, especially when ladders, heavy limbs, or power tools are involved. Wear protective gear, ensure stable footing, and keep bystanders away.
Safety essentials:
Gloves, eye protection, and a helmet
Stable ladder or lift when working overhead
Never cut branches near power lines
Don’t attempt major cuts alone or without proper equipment
If safety is a concern, hiring a professional is the best investment.
Not Considering Tree Species and Growth Habits
Each tree species responds differently to pruning. A technique that improves structure in one species may harm another. Before pruning, research growth rate, disease vulnerability, and seasonal needs.
Examples:
Fruit trees require annual pruning to encourage productive growth.
Flowering trees should be pruned after blooming if they set buds on old wood.
Evergreens typically need minimal pruning and may not recover from aggressive cuts.
A species-specific approach ensures long-term health and a natural shape.
The Right Approach Leads to Stronger, Healthier Trees
Pruning is an essential part of tree care, but improper techniques can cause lasting damage. By pruning at the right time, using proper cuts, prioritising safety, and understanding each tree’s needs, you’ll enhance both structural integrity and visual appeal.
And remember—when in doubt, partner with a professional arborist who can provide expert guidance tailored to your landscape.
