Tree and Root Removal Tips (5 Pro Arborist Techniques)
Let’s get comfortable, folks. Tree and root removal isn’t exactly a walk in the park, but with the right know-how, it can be a whole lot less back-breaking. I’ve spent a good chunk of my life wrestling with stubborn stumps and tangled roots, from the backwoods of Oregon to the rolling hills of Bavaria. Along the way, I’ve picked up a few tricks of the trade that I’m eager to share. This isn’t just textbook knowledge; it’s real-world experience, the kind you can only get from being knee-deep in sawdust and sweat.
This guide focuses on five pro arborist techniques for tree and root removal, designed to help you whether you’re a seasoned logger or just starting out. I’ll cover everything from the initial planning stages to the final cleanup, packed with practical tips, safety advice, and a healthy dose of my own personal experiences.
Initial Site Inspection
- Identify Hazards: Look for overhead power lines (a major electrocution risk!), underground utilities (gas, water, sewer), nearby structures, fences, and anything else that could be damaged or pose a safety risk. Call your local utility companies to mark underground lines. This is a free service and could save your life.
- Tree Species and Size: Knowing the species of tree is crucial. Hardwoods like oak and maple are denser and more difficult to cut than softwoods like pine and fir. Measure the diameter at breast height (DBH) – about 4.5 feet above ground – to estimate the tree’s size and weight. A tree with a DBH of 24 inches can weigh several tons.
- Lean and Limb Structure: Observe the tree’s natural lean and the distribution of its branches. This will influence the direction it will fall and where you need to make your cuts. Uneven limb distribution can cause unexpected shifts during felling.
- Root System: Assess the visible portion of the root system. Are there large surface roots that need to be dealt with? Are there signs of rot or decay that could weaken the tree? A compromised root system can make a tree unstable and unpredictable.
- Environmental Considerations: Check for any protected species of wildlife nesting in the tree. It’s also important to be aware of local regulations regarding tree removal, especially in urban areas. You might need a permit.
Developing a Felling Plan
- Felling Direction: Determine the safest and most practical direction to fell the tree. Consider the tree’s lean, wind direction, obstacles, and your escape routes. Clear a path at a 45-degree angle away from the intended felling direction.
- Cutting Techniques: Decide on the specific cutting techniques you’ll use, such as the open-face felling cut or the bore cut. These techniques are described in detail later in this guide.
- Equipment Selection: Choose the right tools for the job. This includes a chainsaw of appropriate size and power, wedges, a felling lever, ropes, and personal protective equipment (PPE).
- Team Communication: If you’re working with a team, establish clear communication signals and roles. Everyone should know the plan and their responsibilities.
- Emergency Plan: Have a plan in place for dealing with emergencies, such as a tree falling in the wrong direction or someone getting injured. Know the location of the nearest hospital and have a first-aid kit on hand.
Personal Story: I once had to fell a massive oak tree near a historic building. The lean was towards the building, and there were power lines nearby. It was a real head-scratcher. After carefully assessing the situation, I used a combination of winches, ropes, and precision cutting to guide the tree away from the building. It took all day, but we got it down safely without a scratch on anything. The key was meticulous planning and a healthy dose of caution.

2. Advanced Felling Techniques
Once you have a solid plan, it’s time to put it into action. Felling a tree safely and efficiently requires a combination of skill, knowledge, and the right tools.
Open-Face Felling Cut
This is a fundamental technique used for felling trees in a controlled direction.
- The Hinge: The hinge is the key to controlling the direction of the fall. It’s a strip of wood left uncut on the felling side of the tree. The width and thickness of the hinge determine the amount of control you have.
- Hinge Width: Typically, the hinge should be about 80% of the tree’s diameter. For example, on a 20-inch diameter tree, the hinge should be about 16 inches wide.
- Hinge Thickness: The hinge should be about 10% of the tree’s diameter. So, on a 20-inch tree, the hinge should be about 2 inches thick.
- The Face Cut: This cut determines the direction of the fall. It consists of two cuts:
- The Top Cut: This cut is made at a 45-degree angle, sloping downwards towards the center of the tree.
- The Bottom Cut: This cut is made horizontally, meeting the top cut at the desired depth. The depth of the face cut should be about 20% of the tree’s diameter.
- The Back Cut: This cut is made on the opposite side of the tree from the face cut. It should be level and slightly above the bottom cut of the face.
- Leaving the Hinge: The back cut should not meet the face cut. Leave the hinge intact.
- Using Wedges: Insert wedges into the back cut to prevent the tree from pinching the saw and to help direct the fall.
- Wedge Size: Use wedges that are appropriate for the size of the tree. Plastic or aluminum wedges are preferred over steel wedges, as they are less likely to damage your chainsaw if you accidentally hit them.
Bore Cut (or Plunge Cut)
This technique is useful for felling trees with a significant lean or for removing large limbs.
- Safety First: The bore cut is a more advanced technique and requires extra caution. Make sure you have a solid stance and a clear escape route.
- The Bore: Carefully plunge the tip of your chainsaw into the tree, starting on the side opposite the desired felling direction. Use the lower portion of the saw’s guide bar to avoid kickback.
- Creating the Hinge: Once you’ve bored through the tree, carefully cut towards the face cut, leaving the hinge intact.
- Completing the Back Cut: Finish the back cut, leaving the hinge to control the fall.
Using a Felling Lever (Peevy)
A felling lever is a long metal bar with a hinged foot that is used to help push over smaller trees.
- Positioning: Insert the foot of the felling lever into the back cut, behind the hinge.
- Applying Pressure: Use your body weight to apply pressure to the lever, pushing the tree over in the desired direction.
- Safety: Be careful not to overextend yourself. Use your legs to generate power, and keep your back straight.
Data Point: Studies have shown that using proper felling techniques can reduce the risk of accidents by up to 50%.
Personal Story: I once witnessed a logger attempt to fell a large pine tree without using wedges. The tree pinched the saw, and the logger had to scramble to get out of the way as the tree fell in an unexpected direction. It was a close call that could have been avoided by using the right techniques and equipment.
Felling Techniques Comparison
| Technique | Description | Advantages | Disadvantages | Best Use Cases |
|---|---|---|---|---|
| Open-Face Felling | A fundamental technique involving a face cut (top and bottom cuts), a hinge, and a back cut. The hinge controls the direction of the fall. Wedges are often used to prevent pinching and assist in directing the fall. | Provides controlled felling direction; Relatively simple to learn; Safe for most tree types and sizes. | Requires precise cuts to ensure proper hinge formation; Can be challenging in windy conditions or with trees that have a strong lean; May not be suitable for very large trees or trees with significant defects. | General tree felling; Situations where precise control over the fall direction is needed; Beginners and experienced users alike. |
| Bore Cut | Involves plunging the tip of the chainsaw into the tree to create a bore, followed by cutting towards the face cut and completing the back cut. The hinge is carefully maintained to control the fall. | Allows for felling trees with a strong lean; Useful for removing large limbs safely; Can prevent the tree from splitting or barber-chairing. | Requires advanced chainsaw skills and experience; Higher risk of kickback if the saw is not handled properly; Not suitable for beginners; Can be time-consuming for very large trees. | Felling trees with a strong lean; Removing large limbs; Situations where preventing splitting or barber-chairing is critical. |
| Felling Lever | A long metal bar with a hinged foot that is inserted into the back cut to help push over smaller trees. Body weight is used to apply pressure to the lever, assisting in the felling process. | Provides additional leverage for felling trees; Reduces the risk of pinching the saw; Simple to use for smaller trees. | Limited to smaller trees; May not be effective for trees with a strong lean or complex root systems; Requires physical strength and coordination. | Felling smaller trees; Assisting in the felling process when additional leverage is needed; Situations where manual effort is preferred over mechanized methods. |
3. Stump Removal Techniques
Once the tree is down, you’re left with the stump. There are several ways to deal with it, each with its own pros and cons.
Chemical Stump Removal
This is a slow but effective method for killing the stump and hastening its decomposition.
- Chemicals: The most common chemicals used for stump removal are potassium nitrate (stump remover) and glyphosate (herbicide).
- Application: Drill holes into the top of the stump, about 4-6 inches deep and spaced a few inches apart. Pour the chemical into the holes and add water to help it penetrate the wood.
- Time: It can take several months or even a year for the stump to decompose completely.
- Safety: Wear gloves and eye protection when handling chemicals. Follow the manufacturer’s instructions carefully.
Data Point: Chemical stump removal can take anywhere from 6 months to 2 years, depending on the size and species of the stump.
Stump Grinding
This is a faster method that uses a specialized machine to grind the stump into small chips.
- Equipment: Stump grinders are available for rent at most tool rental centers. They come in various sizes, from small walk-behind models to large self-propelled machines.
- Operation: Position the stump grinder over the stump and use the controls to move the grinding wheel back and forth, gradually reducing the stump to below ground level.
- Safety: Wear safety glasses, hearing protection, and heavy gloves. Be aware of flying debris.
- Cleanup: Remove the wood chips and fill the hole with soil.
Excavation
This involves digging around the stump and cutting the roots with an ax, saw, or excavator.
- Manual Excavation: This is the most labor-intensive method, but it’s suitable for smaller stumps.
- Mechanical Excavation: Using an excavator or backhoe can make the job much easier, especially for large stumps.
- Root Removal: Once the stump is free, remove as much of the root system as possible.
- Safety: Wear safety glasses, gloves, and sturdy boots. Be careful when working around heavy machinery.
Burning
This method involves burning the stump down to ground level. It’s effective but can be environmentally damaging and may be restricted in some areas.
- Regulations: Check local regulations before burning a stump. You may need a permit.
- Preparation: Clear a wide area around the stump of any flammable materials.
- Burning: Build a fire on top of the stump and keep it burning until the stump is reduced to ashes.
- Safety: Never leave a burning stump unattended. Keep a water source nearby in case the fire spreads.
Personal Story: I once tried to remove a large oak stump by hand. After a full day of digging and chopping, I had barely made a dent. I finally gave up and rented a stump grinder. It took me about an hour to grind the stump down to below ground level. It was a valuable lesson in the importance of using the right tools for the job.
Stump Removal Methods Comparison
| Method | Description | Advantages | Disadvantages | Best Use Cases |
|---|---|---|---|---|
| Chemical Removal | Involves drilling holes into the stump and applying chemicals (e.g., potassium nitrate, glyphosate) to accelerate decomposition. The chemicals break down the wood fibers, making the stump easier to remove over time. | Relatively easy to apply; Requires minimal physical effort; Can be effective for stumps in remote locations or where machinery access is limited. | Slow process (can take months or years); Chemicals can be harmful to the environment if not used properly; May not be suitable for all tree species; Effectiveness can vary depending on weather conditions and soil type. | Stumps in remote locations; Situations where minimal physical effort is desired; When time is not a critical factor. |

| Excavation | Involves digging around the stump and cutting the roots with an ax, saw, or excavator. The stump is then lifted out of the ground, along with as much of the root system as possible. | Removes the stump and roots completely; No chemicals involved; Can be done manually or with machinery; Can be effective for stumps of any size. | Labor-intensive (especially manual excavation); Can be time-consuming; Disrupts the surrounding soil; Requires disposal of the stump and roots; Potential for damage to underground utilities; Can be hazardous if not done properly. | Rural areas; Situations where complete stump and root removal is required; When manual labor is available; When disruption to the surrounding landscape is not a major concern. |
| Burning | Involves building a fire on top of the stump and allowing it to burn down to ground level. The fire consumes the wood, reducing the stump to ashes. | Relatively easy to implement; Requires minimal equipment; Can be effective for stumps in remote locations; Can be a cost-effective method (if wood is readily available for fuel). | Can be environmentally damaging (air pollution, soil contamination); Fire hazard; May be restricted in some areas; Slow process (can take days or weeks); Leaves behind ashes and charred wood; Can be hazardous if not done properly. | Remote locations; Situations where minimal equipment is available; When environmental concerns are not a major factor; When local regulations permit burning. |
4. Root Management and Soil Restoration
Removing the tree and stump is only half the battle. You also need to deal with the remaining roots and restore the soil.
Root Removal
- Manual Removal: For smaller roots, you can use an ax, saw, or mattock to cut them and remove them from the soil.
- Mechanical Removal: For larger roots, you may need to use an excavator or backhoe.
- Root Raking: A root rake is a specialized attachment for a tractor or skid steer that is used to gather and remove roots from the soil.
- Decomposition: You can also leave the roots in the ground to decompose naturally. This is a slower process, but it can improve soil health.
Soil Amendment
- Testing: Before amending the soil, it’s a good idea to have it tested to determine its pH level and nutrient content.
- Adding Organic Matter: Incorporate organic matter, such as compost, manure, or peat moss, to improve soil structure, drainage, and fertility.
- Adjusting pH: If the soil is too acidic, add lime to raise the pH. If it’s too alkaline, add sulfur to lower the pH.
- Fertilizing: Apply a balanced fertilizer to provide the soil with the nutrients it needs to support plant growth.
Erosion Control
- Mulching: Apply a layer of mulch to the soil to prevent erosion and conserve moisture.
- Seeding: Sow grass seed or plant ground cover to stabilize the soil and prevent erosion.
- Terracing: On slopes, create terraces to slow down water runoff and prevent erosion.
Technical Specification: The ideal soil pH for most plants is between 6.0 and 7.0.
Personal Story: After removing a large willow tree from my yard, the soil was a mess – compacted and depleted of nutrients. I spent several days amending the soil with compost and manure, and then I planted a cover crop of clover. The following spring, the soil was rich and fertile, and I was able to plant a beautiful garden.
Root and Soil Management
| Aspect | Description | Advantages | Disadvantages | Best Use Cases |
|---|---|---|---|---|
| Root Removal | Involves physically removing the remaining roots from the soil after stump removal. This can be done manually with tools like axes and saws, or mechanically with excavators and root rakes. | Prevents regrowth; Improves aesthetics; Facilitates replanting or landscaping; Reduces the risk of tripping hazards. | Labor-intensive; Can be time-consuming; Disrupts the surrounding soil; Requires disposal of the roots; Potential for damage to underground utilities; May not be feasible for large root systems; Can be costly if machinery is required. | Situations where complete root removal is desired; Areas where replanting or landscaping is planned; When preventing regrowth is a priority; When tripping hazards need to be eliminated. |
| Soil Amendment | Involves improving the soil’s physical and chemical properties by adding organic matter (e.g., compost, manure, peat moss), adjusting the pH with lime or sulfur, and fertilizing with a balanced fertilizer. | Improves soil structure; Enhances drainage; Increases fertility; Provides essential nutrients for plant growth; Promotes healthy root development; Supports beneficial soil microorganisms. | Requires soil testing to determine nutrient deficiencies and pH imbalances; Can be costly if amendments need to be purchased; Requires knowledge of soil science and plant nutrition; May not be effective in severely degraded soils; Can be time-consuming to implement. | Situations where soil quality is poor; Areas where replanting or landscaping is planned; When improving soil health and fertility is a priority; When supporting healthy plant growth is desired. |
