I can’t tell you how many times I’ve heard the same complaint: “Cutting tree roots is a nightmare! My chainsaw gets dull, kicks back, and the results are always messy.” I understand the frustration. I’ve spent years felling trees and dealing with the gnarly root systems they leave behind. It’s a tough job, but with the right techniques and a little know-how, you can achieve cleaner, safer, and more efficient results. In this guide, I’ll share my top five pro techniques for cutting tree roots, gleaned from years of experience in the field. Let’s get started!

Tree Root Cutting Tips (5 Pro Techniques for Cleaner Results)

1. Assessing the Situation and Planning Your Attack

Before I even think about firing up my chainsaw, I take a good look at the situation. Rushing into root cutting is a recipe for disaster.

• Understanding the Root System: Tree root systems are vast and complex. Some trees have deep taproots, while others have shallow, spreading roots. Understanding the type of root system you’re dealing with is crucial. For example, oak trees tend to have deep taproots, while maple trees have more shallow, spreading roots.
• Identifying Utilities: This is non-negotiable. Call your local utility companies before you start digging or cutting. Hitting a gas line or electrical cable is not only dangerous but also expensive. I always use the “Call Before You Dig” service (811 in the US) to ensure I’m clear of any underground hazards.
• Evaluating Soil Conditions: Is the soil dry and sandy, or wet and clay-like? This will affect how easily you can dig around the roots and how much dirt will cling to them. Wet clay is the worst; it’s heavy and abrasive, dulling your chain quickly.
• Determining Root Size and Quantity: How thick are the roots you need to cut? Are there just a few large roots, or a dense network of smaller ones? This will help you choose the right tools and techniques.
• Planning the Cuts: Think about where you need to make the cuts to achieve your desired outcome. Are you removing the entire stump, or just clearing a path for landscaping? Visualize the cuts before you start.
• Personal Story: I remember one time I was so eager to get a stump out that I skipped the planning stage. I ended up cutting through a sprinkler line, creating a muddy mess and delaying the project by a whole day! Lesson learned: always plan ahead.

Takeaway: A thorough assessment is the foundation of a successful root-cutting project. Take the time to understand the root system, identify potential hazards, and plan your cuts before you start.

2. Preparing Your Tools and Safety Gear

Having the right tools and safety gear is essential for efficient and safe root cutting. Don’t skimp on quality or safety.

• Chainsaw Selection: For most root-cutting jobs, I recommend a chainsaw with a bar length of 16-20 inches. A gas-powered saw is ideal for larger roots, while an electric or battery-powered saw can be sufficient for smaller roots. I personally prefer a Stihl MS 271 Farm Boss for its power and reliability.
• Chainsaw Chain Type: Use a chain specifically designed for dirty conditions. Chains with carbide-tipped cutters are more resistant to dulling from dirt and rocks. I keep a few spare chains on hand so I can swap them out quickly when they get dull.
• Digging Tools: A sturdy shovel, pickaxe, and digging bar are essential for exposing the roots. A mattock is also useful for cutting smaller roots and loosening soil.
• Root Pruning Saw: A manual root pruning saw is great for making clean cuts on smaller roots, especially in tight spaces where a chainsaw is difficult to maneuver.
• High-Pressure Washer: A high-pressure washer can be incredibly helpful for cleaning dirt and debris off the roots before cutting. This will significantly extend the life of your chainsaw chain.
• Safety Gear: This is non-negotiable. Always wear the following:
  • Chainsaw Chaps: Protect your legs from accidental cuts.
  • Steel-Toed Boots: Protect your feet from falling debris and chainsaw mishaps.
  • Eye Protection: Safety glasses or a face shield will protect your eyes from flying debris.
  • Hearing Protection: Chainsaws are loud. Wear earplugs or earmuffs to protect your hearing.
  • Gloves: Protect your hands from cuts and abrasions.
  • Helmet: A helmet is essential for protecting your head from falling branches and other hazards.
• Maintenance Tools: Keep your chainsaw in good working order with regular maintenance. This includes sharpening the chain, cleaning the air filter, and checking the oil and fuel levels.
• Original Insight: I’ve found that investing in a good quality chainsaw sharpener is worth its weight in gold. A sharp chain cuts faster, safer, and with less effort. I use a Granberg Bar-Mount Chain Sharpener and it keeps my chains razor sharp.

Takeaway: Having the right tools and safety gear is crucial for a safe and efficient root-cutting project.

3. Exposing the Roots: Digging and Cleaning

Before you can cut the roots, you need to expose them. This involves digging around the stump and cleaning the roots to remove dirt and debris.

• Digging Around the Stump: Start by digging a wide circle around the stump, gradually working your way down. The diameter of the circle will depend on the size of the stump and the spread of the roots. I usually start with a circle that’s about twice the diameter of the stump.
• Using the Right Digging Tools: Use a shovel to remove loose soil, a pickaxe to break up compacted soil, and a digging bar to pry out larger rocks and roots. A mattock is also useful for cutting smaller roots and loosening soil.
• Cleaning the Roots: Once you’ve exposed the roots, use a high-pressure washer to clean off any dirt, rocks, and debris. This will significantly extend the life of your chainsaw chain. If you don’t have a pressure washer, you can use a garden hose with a nozzle attachment.
• Dealing with Obstacles: You may encounter rocks, pipes, or other obstacles while digging. Be careful not to damage these obstacles. If you encounter a pipe, call your local utility company to determine its purpose and how to proceed.
• Safety Considerations: Be careful when digging around the stump. The soil can be unstable, and you don’t want to get trapped in a collapse. Always dig at a safe angle and avoid undermining the stump.
• Personal Story: I once spent an entire day digging around a massive oak stump, only to discover that it was wrapped around a huge boulder. I had to use a sledgehammer and chisels to break up the boulder before I could finally remove the stump. It was a grueling experience, but it taught me the importance of patience and perseverance.

Takeaway: Exposing the roots is a crucial step in the root-cutting process. Take your time, use the right tools, and be careful when digging around the stump. Cleaning the roots before cutting will significantly extend the life of your chainsaw chain.

4. Making the Cuts: Chainsaw Techniques for Root Cutting

Once the roots are exposed and clean, it’s time to start cutting. Here are some chainsaw techniques that I’ve found effective for root cutting:

• Cutting Large Roots: For large roots, use a plunge cut. Start by making a small notch on the top of the root, then carefully plunge the tip of the chainsaw bar into the root. Work the saw back and forth until you’ve cut through the root. Be careful to avoid kickback.
• Cutting Smaller Roots: For smaller roots, you can use a standard cutting technique. Hold the chainsaw firmly with both hands and guide the bar through the root. Keep the chain sharp and avoid forcing the saw.
• Avoiding Kickback: Kickback is a dangerous phenomenon that occurs when the tip of the chainsaw bar contacts a solid object. To avoid kickback, always keep the tip of the bar away from the ground and other obstacles. Use a reduced-kickback chain and maintain a firm grip on the saw.
• Cutting at an Angle: Cutting roots at an angle can make it easier to remove the stump and prevent it from re-sprouting. Angle the cuts so that the top of the root is slightly higher than the bottom.
• Working in Sections: If the roots are very large or dense, work in sections. Cut the roots into smaller pieces that are easier to handle and remove.
• Using Wedges: If a root is pinching the chainsaw bar, use wedges to keep the cut open. This will prevent the saw from getting stuck and make it easier to complete the cut. I prefer using plastic wedges, as they won’t damage the chain if you accidentally cut into them.
• Case Study: I once worked on a project where we had to remove a large number of tree stumps from a construction site. We used a combination of plunge cuts and standard cutting techniques to remove the roots. We also used wedges to keep the cuts open and prevent the saw from getting stuck. By working efficiently and safely, we were able to complete the project on time and within budget.
• Original Insight: I’ve found that it’s helpful to use a chainsaw with a chain brake. The chain brake stops the chain instantly if kickback occurs, reducing the risk of injury.

Takeaway: Using the right chainsaw techniques is essential for safe and efficient root cutting. Always be aware of the potential for kickback and take steps to avoid it. Work in sections if necessary and use wedges to keep the cuts open.

5. Stump Removal and Disposal

Once you’ve cut the roots, it’s time to remove the stump and dispose of the debris.

• Removing the Stump: Depending on the size of the stump, you may be able to remove it manually with a shovel and digging bar. For larger stumps, you may need to use a stump grinder or hire a professional tree service.
• Using a Stump Grinder: A stump grinder is a machine that grinds the stump into small chips. This is a relatively quick and easy way to remove a stump, but it can be expensive to rent or hire a stump grinder.
• Hiring a Professional Tree Service: If you’re not comfortable removing the stump yourself, you can hire a professional tree service. They have the equipment and expertise to remove stumps safely and efficiently.
• Disposing of the Debris: Once you’ve removed the stump, you’ll need to dispose of the debris. You can chip the wood and use it as mulch, or you can haul it away to a landfill or composting facility.
• Filling the Hole: After removing the stump, fill the hole with topsoil and compact it firmly. You may need to add more soil over time as it settles.
• Replanting: Consider replanting a tree in the same location. Choose a tree species that is well-suited to the soil and climate.
• Personal Story: I once tried to remove a large stump by myself using a come-along winch. It was a slow and arduous process, and I ended up breaking the winch. I finally gave up and hired a professional tree service to remove the stump. It was the best decision I ever made.
• Original Insight: I’ve found that it’s helpful to use a root killer to prevent the stump from re-sprouting. Apply the root killer to the freshly cut surface of the stump according to the manufacturer’s instructions.

Takeaway: Removing the stump and disposing of the debris is the final step in the root-cutting process. You can remove the stump manually, use a stump grinder, or hire a professional tree service. Dispose of the debris responsibly and fill the hole with topsoil. Consider replanting a tree in the same location.

Advanced Techniques: Root Barriers and Chemical Root Control

For those dealing with persistent root encroachment issues, there are advanced techniques that can provide long-term solutions.

• Root Barriers: These are physical barriers installed in the ground to prevent roots from spreading into unwanted areas. They are typically made of plastic or metal and are buried vertically along property lines, near foundations, or around sensitive areas like septic systems.
  • Installation: Root barriers should be installed deep enough to intercept the majority of roots. A depth of 24-36 inches is generally recommended. The barrier should also extend above ground a few inches to prevent surface roots from growing over it.
  • Materials: Choose a durable, high-quality root barrier material that can withstand soil conditions and root pressure. Copper-based barriers are particularly effective as they release ions that inhibit root growth.
  • Case Study: A homeowner in California was struggling with tree roots invading their sewer line. After repeated blockages and costly repairs, they installed a copper root barrier along the property line. The barrier effectively prevented further root intrusion, saving the homeowner thousands of dollars in future repairs.
• Chemical Root Control: This involves using herbicides to kill or inhibit root growth. This method should be used with caution as it can potentially harm desirable plants and the environment.
  • Application: Chemical root control products are typically applied directly to the soil around the tree or injected into the root system. Follow the manufacturer’s instructions carefully.
  • Herbicides: Common herbicides used for root control include glyphosate and dichlobenil. These herbicides are systemic, meaning they are absorbed by the roots and translocated throughout the plant.
  • Safety Precautions: When using chemical root control products, wear appropriate safety gear, including gloves, eye protection, and a respirator. Avoid applying herbicides on windy days to prevent drift.
• Original Insight: I’ve found that combining root barriers with chemical root control can be a highly effective strategy for managing persistent root encroachment issues. The root barrier provides a physical barrier to prevent root spread, while the herbicide kills any roots that manage to penetrate the barrier.

Takeaway: Root barriers and chemical root control are advanced techniques for managing persistent root encroachment issues. Root barriers provide a physical barrier to prevent root spread, while chemical root control uses herbicides to kill or inhibit root growth. Use these techniques with caution and follow the manufacturer’s instructions carefully.
