Introduction: A Question We’re Often Asked
From time to time, customers or curious neighbors ask us, “Do you use shark oil for tree wounds?” If you’ve searched online or heard stories about traditional tree care, you might have come across shark oil as a recommended treatment for tree wounds. Here at Branch Management Tree Service, we believe in transparency and education—so let’s dive into the origins of shark oil in arboriculture and share why sustainable, modern practices are always our choice.
What is Shark Oil and Why Was It Used on Trees?
Shark oil is an oil traditionally extracted from the liver of certain deep-sea sharks. In countries like India and Sri Lanka, it’s been used for generations as a sealant applied to pruning cuts and wounds on trees, especially coconut and palm species. Its thick, water-resistant consistency was believed to protect exposed wood from fungal infections, pest invasions, and harsh weather.
Why did people think it worked?
- Shark oil contains squalene and natural fatty compounds that, for a short time, form a physical barrier over a fresh cut.
- In tropical, humid environments, any sealant could slow fungal or borer attack while a tree begins to compartmentalize and heal a wound.
Does Shark Oil Really Help Trees? Science and Tradition Collide
Modern arboricultural science shows us that while a barrier (any thick oil or wax) might provide some temporary protection, the real healing is done by the tree itself. Trees “wall off” damage with new wood and chemical barriers—a process called compartmentalization. No dressing, whether animal- or plant-based, can replace that biological process.
For most species, especially in temperate climates like ours, research finds there’s little long-term benefit to wound dressings. The healthiest healing comes from:
- Proper pruning technique (clean cuts, correct angles)
- Keeping trees healthy (good soil, moisture, and sunlight)
- Only using a wound dressing when pest or disease risk is high
The Ethical and Environmental Problem with Shark Oil
Perhaps the biggest reason for moving away from shark oil is ethics and sustainability:
- Shark populations are declining worldwide. Many are now threatened or endangered due to overfishing and extraction for products like oil.
- Modern environmental standards ban or discourage products made from endangered wildlife, including sharks.
- Alternatives are readily available that are as effective, safer, and much better for the planet.
What Does Branch Management Tree Service Use Instead?
We are proud to say:
Branch Management Tree Service never uses shark oil or animal-based products for tree wound treatments.
Our approach:
- We rely on scientifically approved synthetic or plant-based wound sealants when needed (and only for large, high-risk wounds).
- Pruning cuts are made with sharp, sterilized tools at the right place for each species.
- We emphasize overall tree health—mulch, soil care, and correct watering—which is the best defense your tree has.
Eco-friendly alternatives you might see us use:
- Biodegradable pruning sealants made from plant oils or beeswax
- Organic and OMRI-listed products
- Products backed by decades of research and proven safety
We’re happy to show you what we use at any job—just ask!
Why It Matters: Trees, Ecosystems, and Our Business Ethics
Responsible tree care isn’t just about good results today—it’s about preserving the environment for future generations. By avoiding wildlife-derived products like shark oil, we help:
- Protect endangered marine life
- Uphold ethical standards
- Ensure the ecosystem remains healthy—from your backyard tree to the world’s oceans
Conclusion: Our Promise To You
At Branch Management Tree Service, our goal is to deliver superior tree health and safety—without cutting corners or risking the environment. Shark oil may have a place in arboricultural history, but sustainable science drives professional tree care forward.
