Why Climbing Spikes Shouldn’t Be Used for Tree Trimming?
When it comes to tree care, there’s a fine line between proper maintenance and causing long-term damage. One of the most common mistakes made by inexperienced or untrained tree workers is using climbing spikes (also called spurs or gaffs) during routine trimming or pruning. While these tools can be necessary in some situations, their misuse can jeopardize the very health of the trees they’re meant to preserve.
Here’s why using climbing spikes for tree trimming is harmful—and why they should only be used for tree removal.
The Damage Climbing Spikes Cause
Each time a climber takes a step, those spikes puncture the bark and underlying tissue of the tree. This might not seem like a big deal, but trees rely on their outer layers for vital processes like nutrient transport and protection against pests and disease.
Here’s what happens when spikes are used on a living tree:
• Wounds and Scarring: Every puncture creates an open wound. These wounds may not heal properly, especially if the tree is already stressed.
• Increased Risk of Infection: Each spike hole can become a pathway for bacteria, fungi, and insects that lead to decay.
• Disrupted Nutrient Flow: Trees transport water and nutrients just beneath the bark. Damaging this layer affects the tree’s ability to nourish itself.
• Permanent Structural Weakness: Repeated damage can lead to weak points in the trunk that increase the risk of breakage in storms or high winds.
• Stunted Growth and Decline: Over time, a tree that’s repeatedly damaged by spikes can go into decline, losing vitality and even dying prematurely.
When Are Climbing Spikes Acceptable?
There’s one main exception: Tree Removal
When a tree is being cut down, its long-term health is no longer a concern. In these cases, spikes can help climbers safely and efficiently dismantle the tree section by section.
The Professional Standard
Any reputable and experienced treecare companies would never use spikes for any routine pruning. Instead, we use several other non-invasive strategies involving advanced rigging/srt climbing techinques, aerial lifts, or cranes(when necessary).: All of which are important methods that were originally developed to protect both the tree and the people around them.
If you’re hiring someone to work on your trees, ask them upfront: “Do you use climbing spikes for trimming?” If the answer is yes, it’s a red flag.
Healthy Trees Start With Proper Care
Trees are long-living organisms that add beauty, value, and environmental benefits to your property. But improper care—like using climbing spikes during trimming—can cause irreversible harm.
Stick with professionals who put tree health first and use spike-free climbing methods unless removal is the goal. Your trees will thank you with stronger growth, better appearance, and a longer life.
