will removing tree roots above ground kill the tree
The short answer is: yes, it definitely can. While cutting a single tiny fiber might not do much, removing significant surface roots often leads to a slow or even rapid decline in tree health. Trees rely on their root systems for two primary reasons: structural stability and nutrient absorption.
When you remove a root that has grown above ground, you are essentially amputating a limb that the tree uses to “eat” and “breathe.” These surface roots are often the most active in collecting oxygen and moisture from the top layer of soil. Cutting them creates an open wound that invites pathogenic fungi and wood-rotting organisms into the heart of the tree.
Furthermore, those large, visible roots are often the main anchors holding the tree upright. If you remove a major structural root on one side, the tree may become unstable. This creates a massive safety risk for your home, RV, or tent, especially during high winds or heavy seasonal storms.
Why Do Tree Roots Grow Above Ground?
It is a common misconception that roots “come up” out of the ground. In reality, most surface roots start underground and grow thicker over time. As the diameter of the root increases, it eventually breaks through the soil surface, especially if the topsoil has eroded away.
Soil Compaction and Oxygen
Trees need oxygen to survive, and they get it through the pores in the soil. If you have heavy foot traffic, or if you frequently park an overlanding vehicle near a tree, the soil becomes compacted. This forces the roots to grow closer to the surface where they can actually find air to breathe.
Natural Species Tendencies
Some trees are simply genetically predisposed to having shallow root systems. Maples, Willows, and Beech trees are notorious for “snaking” roots that eventually surface. If you are planning a homestead garden, knowing which species do this can help you pick the right spot for planting.
Erosion and Weathering
Over years of heavy rain or wind, the soil covering a root system can wash away. This is common on sloped terrain or in areas without enough ground cover. Once the soil is gone, the root is exposed to the elements, making it a target for lawnmowers and foot traffic.
The Critical Difference Between Feeder Roots and Anchor Roots
To understand why you should be careful, you need to know what you are looking at. Not all roots serve the same purpose. Before you decide if will removing tree roots above ground kill the tree is a risk you want to take, identify the root type.
Structural Anchor Roots
These are the thick, woody roots that radiate out from the root flare at the base of the trunk. They act like the foundation of a house. Removing even one of these can lead to the tree leaning or falling over. Never cut a root that is larger than two inches in diameter if it is close to the trunk.
Fine Feeder Roots
These are the smaller, hair-like roots that branch off the main system. They do the heavy lifting when it comes to absorbing water and minerals. While losing a few feeder roots won’t kill the tree, losing a large patch of them can cause canopy dieback or leaf yellowing.
Signs Your Tree Is Already Stressed
Before you even consider pruning a root, look up at the leaves. If the tree is already struggling, any root removal could be the final blow. A healthy tree can sometimes handle minor root loss, but a stressed tree cannot.
- Yellowing Leaves: If the leaves are turning yellow out of season, the tree may be struggling to get nutrients.
- Dead Branches: Look for “stag-headedness,” where the very top branches of the tree are bare and brittle.
- Fungal Growth: Mushrooms growing at the base of the tree or on the roots themselves indicate internal decay.
- Thinning Canopy: If you can see much more sky through the branches than in previous years, the tree is losing vigor.
Safe Alternatives to Cutting Surface Roots
Since we know that will removing tree roots above ground kill the tree is a high-probability outcome for many species, let’s look at safer ways to manage the problem. You don’t have to choose between a flat lawn and a dead tree.
The Power of Mulching
The best way to “hide” surface roots is to stop trying to grow grass over them. Grass and trees are actually competitors for water and nutrients. Instead, create a mulch island around the base of the tree. This protects the roots from mower damage and keeps the soil moist.
Use organic wood chips or shredded bark. Apply a layer about 2 to 3 inches deep, but make sure you do not pile it up against the trunk (the “mulch volcano” mistake). This provides a soft walking surface and eliminates the need to mow near the exposed roots.
Planting Shade-Tolerant Ground Cover
If you don’t like the look of plain mulch, try planting ground covers that thrive in the shade. Plants like Pachysandra, Vinca, or certain types of moss can grow around the roots. This creates a beautiful, naturalized look that requires no mowing and protects the tree’s foundation.
Creating a Physical Barrier
If the root is a major tripping hazard on a path, consider building a small boardwalk or a raised wooden walkway over the area. This allows the root to grow undisturbed while providing a flat, safe surface for you to walk on. This is a common solution in professional trail building and park management.
Step-by-Step: How to Safely Manage Exposed Roots
If you have consulted a professional and decided that a small, non-structural root must go, you must do it correctly. Careless hacking with a dull shovel will lead to root rot and long-term decline.
- Identify the Root: Ensure the root is small (less than 2 inches thick) and far away from the trunk. A good rule of thumb is to stay outside the drip line of the canopy.
- Expose the Area: Carefully dig away the soil around the section of the root you plan to remove. Use a small hand trowel to avoid nicking other healthy roots.
- Use Sharp Tools: Use a sharp pruning saw or bypass loppers. A clean cut heals much faster than a jagged tear. Clean your tools with isopropyl alcohol before and after to prevent spreading disease.
- Make a Clean Cut: Cut the root cleanly at a slight angle. Do not use “wound paint” or sealants; trees have their own natural way of “walling off” injuries (a process called CODIT).
- Backfill with Quality Soil: Once the cut is made, cover the remaining root ends with a mix of native soil and organic compost. This encourages the tree to grow new feeder roots in the area.
When to Call a Certified Arborist
Sometimes, a DIY approach isn’t enough. If you are dealing with a massive tree near your home or power lines, the stakes are too high. An International Society of Arboriculture (ISA) certified arborist can perform a “Root Pruning” service using specialized tools like an air spade.
An air spade uses compressed air to blow away soil without damaging the delicate bark of the roots. This allows the expert to see exactly what they are doing before making a single cut. If you are worried that will removing tree roots above ground kill the tree in your specific yard, professional consultation is the only way to be 100% sure.
Call an expert if you see significant leaning, large cracks in the soil near the base, or if the roots are lifting your driveway or foundation. These are structural issues that require more than just a pruning saw.
Tools You Might Need for Root Management
If you’re a homesteader or an active gardener, having the right kit makes a world of difference. Here are a few essential tools for managing tree health and landscape safety:
- Pruning Saw: A folding saw is great for campers and hikers, but a fixed-blade pruning saw is better for heavy root work.
- Bypass Loppers: These provide a clean, scissor-like cut for smaller roots.
- Hand Trowel: For delicate excavation around the root flare.
- Steel Rake: Useful for spreading mulch evenly without damaging the tree’s bark.
- Measuring Tape: To ensure you are staying a safe distance (usually 3-5 times the trunk diameter) away from the base.
Frequently Asked Questions About Tree Roots
Can I cover surface roots with topsoil?
You can, but you must be extremely careful. Adding more than 1 or 2 inches of heavy soil can suffocate the roots by cutting off their oxygen supply. It is much safer to use a light, airy mulch or a mix of compost and wood chips.
Will cutting roots make my tree fall over?
It is a very real possibility. Large surface roots provide lateral stability. If you cut the roots on the side the wind usually blows from, the tree loses its “guy wires” and can topple during a storm.
How far away from the tree can I safely cut a root?
The general rule is to stay at least 3 to 5 feet away from the trunk for every inch of trunk diameter. However, for most backyard trees, staying outside the “drip line” (the area directly under the outer edge of the branches) is the safest bet.
What happens to the tree after a root is removed?
The tree will attempt to “compartmentalize” the wound to prevent decay. However, this requires a lot of energy. You may see stunted growth or fewer leaves in the following season as the tree redirects its resources to healing.
Is there a “safe” time of year to prune roots?
Late winter or early spring, while the tree is still dormant, is generally the best time. This gives the tree a chance to begin the healing process before the high-stress heat of summer arrives.
Final Thoughts on Tree Root Removal
Living a more self-reliant and outdoor-focused lifestyle means learning to respect the natural systems around us. While those surface roots might be an eyesore or a nuisance, they are the lifeline of the trees that provide us with shade, oxygen, and beauty. Before you act, always weigh the convenience of a flat lawn against the value of a mature, healthy tree.
Remember that will removing tree roots above ground kill the tree is a question with high stakes. In most cases, the best solution is to adapt your landscape to the tree rather than forcing the tree to adapt to you. Use mulch, plant ground covers, or build walkways to keep your homestead safe and your trees standing tall.
Take care of your land, and your land will take care of you. Whether you’re clearing a spot for a new off-grid cabin or just tidying up the backyard, always prioritize the long-term health of your ecosystem. Stay safe and stay grounded!
