Common Tree Trimming Mistakes and How to Avoid Them

Tree trimming may seem like a simple task, but doing it wrong can cause long-term damage to your trees and even create safety hazards. Many homeowners attempt to handle tree trimming themselves without realizing that improper techniques can lead to disease, weak limbs, or an unsightly appearance. At Salas Services, we’ve seen these mistakes firsthand—and we’re here to help you avoid them.

Whether you’re trimming to maintain aesthetics, encourage healthy growth, or protect your property, avoiding these common tree trimming mistakes is key.

1. Topping the Tree

What it is: Topping is the drastic removal of large branches or the entire top of a tree.

Why it’s a problem: Topping stresses trees, encourages weak regrowth, and leaves them vulnerable to disease and pests. It also ruins the natural shape of the tree.

How to avoid it: Instead of topping, opt for selective thinning or reduction cuts that maintain the tree’s structure while reducing size.

2. Over-Pruning

What it is: Removing more than 25% of a tree’s canopy in one season.

Why it’s a problem: Over-pruning can starve the tree of nutrients, reduce its ability to photosynthesize, and increase susceptibility to disease and sunscald.

How to avoid it: Trim moderately and with purpose. Every cut should have a reason—whether it’s removing dead wood, improving shape, or encouraging new growth.

3. Ignoring the Branch Collar

What it is: Cutting a branch flush with the trunk, instead of just outside the swollen area known as the collar.

Why it’s a problem: The collar contains protective cells that help the tree seal the wound. Cutting into it slows healing and increases infection risk.

How to avoid it: Always cut just outside the branch collar without damaging it. This promotes faster healing and reduces disease entry points.

4. Using Dull or Dirty Tools

What it is: Trimming with blades that are dull, rusty, or unclean.

Why it’s a problem: Dull tools tear instead of cleanly slicing, leading to jagged wounds. Dirty tools can spread disease from one plant to another.

How to avoid it: Keep tools sharp and disinfect them before and after trimming. Professionals like Salas Services use sanitized, high-quality equipment on every job.

5. Trimming at the Wrong Time of Year

What it is: Cutting back trees during the wrong season, particularly during active growth or dormancy.

Why it’s a problem: Poor timing can shock the tree or expose it to pests and disease.

How to avoid it: The best time for most tree trimming is late winter to early spring before new growth begins. Some species may have specific requirements—consult an expert if unsure.

6. Failing to Remove Dead or Diseased Branches

What it is: Ignoring obvious signs of decay, fungus, or dieback.

Why it’s a problem: Dead branches pose a safety hazard and can spread disease to healthy parts of the tree.

How to avoid it: Regular inspections and proactive pruning are essential. Removing dead or diseased limbs helps your tree stay healthy and strong.

7. DIYing Large or High Branches

What it is: Attempting to cut large limbs or reach high branches without proper safety equipment or experience.

Why it’s a problem: This is one of the most dangerous mistakes, often leading to injury or property damage.

How to avoid it: Always call a professional tree trimming service for large or high-up cuts. Safety is never worth compromising.
