Dealing with unwanted roots in the yard is a common challenge for homeowners, presenting issues ranging from minor landscape obstruction to significant structural damage threats. Surface roots create tripping hazards and make mowing difficult, while deeper roots can invade plumbing or compromise foundations. Understanding the nature of the root problem is the first step toward effective management. This article outlines strategies for assessing, removing, and mitigating root issues to reclaim your yard space safely and efficiently.
Assessing the Root Source and Potential Risks
Before attempting root removal, identify the source and evaluate the potential consequences. Determine if the root belongs to a living tree, a dead stump, or another plant, as this dictates the appropriate removal method. Roots from established, living trees require the greatest caution because they anchor the tree and absorb water and nutrients.
A significant risk is the potential to destabilize or kill a healthy tree. Avoid cutting any root that is larger than two inches in diameter or located within the tree’s dripline, especially if it is close to the trunk. Removing too many large roots can compromise the tree’s structural integrity, making it susceptible to falling during high winds. Always contact 811 before digging to ensure no underground utility lines, such as gas or electrical cables, are present in the work area.
DIY Methods for Root Removal and Mitigation
For smaller, non-structural roots or those belonging to dead vegetation, manual removal is a feasible option using common household tools. Dig away the soil around the problematic root using a shovel or a mattock to fully expose the section you intend to cut. Exposing the root allows for a clean, targeted cut that minimizes damage to the surrounding soil or nearby roots.
Once the root is exposed, use loppers for thin roots or a hand saw or reciprocating saw fitted with a wood-cutting blade for thicker ones. Making a clean cut is important to prevent jagged edges that could invite disease or pests if the source tree is still alive. After the cut is made, the exposed section of the root can be pulled free and the remaining hole can be backfilled with soil.
If you are dealing with a stump or roots from a tree that has already been removed, chemical application can accelerate the natural decay process. A strong herbicide containing glyphosate, or a natural solution like rock salt or Epsom salt, can be applied directly to the cut surface. Drill several holes into the exposed root or stump, pour the chosen chemical agent into the holes, and then add a small amount of water to help the product absorb deep into the wood fibers. This method works by drawing moisture out of the root tissue or introducing a substance that destroys the vascular system, leading to faster wood breakdown.
In situations where surface roots from a healthy tree cannot be cut, mitigation techniques can help manage the hazard without harming the tree. One approach is to cover the exposed roots with a thin layer of topsoil and then a layer of organic mulch. This can smooth out the surface and reduce the tripping hazard. Avoid mounding the soil too high against the trunk, as this can encourage rot and disease. Alternatively, modifying the area by diverting pathways or creating raised beds around the roots allows you to work with the tree’s natural growth pattern.
When to Seek Professional Assistance
Certain root problems exceed the scope of a typical DIY project and require specialized knowledge and equipment. If a root is larger than two inches in diameter and is close to a mature, living tree, consulting a certified arborist is necessary. An arborist can perform a risk assessment to determine if cutting the root will compromise the tree’s stability, offering advice on root pruning techniques that prioritize the tree’s health and safety.
Large, established stumps and their associated root systems are best handled by a professional stump grinding service. These specialists use heavy machinery with a rotating cutting wheel to grind the wood down several inches below the soil line. Stump grinding is faster and less labor-intensive than manual removal and effectively eliminates the root crown, preventing the stump from sprouting new growth.
Root intrusion into plumbing lines is a serious issue that warrants immediate professional help. Signs often include multiple slow drains, gurgling noises from toilets, or foul odors in the yard or home. Plumbers or specialized drain technicians can use a camera inspection to confirm the presence of roots and then employ high-pressure hydro-jetting to cut and flush the root mass from the pipe.
For ongoing problems near permanent structures, professionals can install physical root barriers. These barriers, typically made of high-density polyethylene or a specialized geotextile fabric, are trenched vertically into the soil to redirect root growth. This solution prevents future damage by mechanically guiding the roots downward and away from foundations, driveways, or utility lines, while preserving the health of the tree.
