Planting a young tree means giving it adequate support for healthy growth — tree supports protect young trees from wind, heavy snow, and other environmental stressors that can cause damage or uprooting. Wooden stakes have traditionally been the go-to choice, but fiberglass tree supports have gained popularity in recent years for their superior properties. Here’s a look at the pros and cons of both, to help you make the right call for your trees.
Fiberglass Tree Supports
Fiberglass tree supports are made from a composite combining glass fibers with resin — a strong, lightweight, durable product.
Pros
Durability: fiberglass tree supports resist rot, decay, and insects, giving them a longer lifespan than wooden stakes.
Flexibility: bend without breaking, allowing natural tree movement and reducing girdling risk.
Strength: excellent tensile strength, providing reliable support for young trees.
Lightweight: easier to handle and install than wooden stakes.
Corrosion-resistant: not susceptible to rust or corrosion, ideal for outdoor use.
Long-lasting: with proper care, can last for many years.
Cons
Cost: generally more expensive than wooden stakes.
Environmental impact: the fiberglass manufacturing process can carry environmental implications.
Traditional Tree Supports
Wooden tree stakes have supported young trees for centuries, typically made from durable hardwoods like oak or cedar.
Pros
Cost-effective: generally more affordable than fiberglass supports.
Readily available: easy to find at most garden centers and hardware stores.
Cons
Durability: susceptible to rot, decay, and insect damage, requiring frequent replacement.
Rigidity: can restrict tree movement, potentially leading to girdling.
Environmental impact: treated wood can introduce chemicals into the soil.
Fiberglass vs. Wood: A Comparison
| Feature | Fiberglass Tree Supports | Traditional Tree Supports |
| Durability | Highly durable, resistant to rot and decay | Susceptible to rot, decay, and insect damage |
| Flexibility | Flexible, allows for natural tree movement | Rigid, can restrict tree movement |
| Strength | High tensile strength | Moderate strength |
| Weight | Lightweight | Heavier |
| Cost | Higher | Lower |
| Environmental Impact | Higher manufacturing impact | Potential for chemical runoff from treated wood |
| Lifespan | Long-lasting | Shorter lifespan |
When to Choose Fiberglass Tree Supports
Long-term support: for a long-lasting, low-maintenance solution, fiberglass is an excellent choice.
Harsh climates: fiberglass supports resist rot and decay, well suited to extreme weather.
Valuable trees: for high-value trees, the extra durability and longevity can be a worthwhile investment.
When to Choose Traditional Tree Supports
Budget-conscious: if cost is the main concern, wooden stakes are the more affordable option.
Temporary support: wooden stakes work well for short-term needs.
Conclusion
Choosing between fiberglass and traditional tree supports depends on budget, climate, and your trees’ specific needs. Fiberglass tree supports offer superior durability, flexibility, and longevity, while wooden stakes remain a cost-effective option for many applications. Weighing the pros and cons of each helps ensure your trees get the support they need to grow healthy.
Additional Tips
Proper installation: whichever support you choose, correct installation is crucial for good results.
Regular inspection: periodically check your tree supports for damage or wear.
Remove supports when no longer needed: once a tree is established, remove supports to prevent girdling.
Following these guidelines helps give your trees the support they need to thrive.
