How To Address And Manage Exposed Tree Roots
Trees bring numerous benefits to any property—they provide shade, help prevent soil erosion, and enhance the overall visual appeal of your landscape. However, as trees grow, they can present certain challenges, particularly when roots start surfacing. Exposed tree roots not only look unsightly but can also lead to damaged lawn equipment, uneven sidewalks, and compromised irrigation systems.
If you’re dealing with tree roots above ground and wondering what to do, you have options. Here, we’ll explore practical ways to manage exposed tree roots, reduce the risk of damage, and improve the appearance of your landscape.
Why Do Tree Roots Become Exposed?
While mature trees are valuable assets in any landscape, their roots sometimes break through the surface. But why does this happen? There are a few key reasons why tree roots become exposed:
Natural Root Growth: Just like the tree trunk thickens over time, the roots expand as the tree matures. This growth can cause roots to push upward and emerge from the ground.
Soil Erosion: Rain, runoff, and wind can wear away the soil around a tree’s base, gradually exposing the roots.
Limited Space for Root Expansion: When trees are planted in confined spaces—such as near sidewalks, buildings, or driveways—the roots may have nowhere to grow but upward.
Risks of Ignoring Exposed Tree Roots
Exposed roots can lead to several problems, both for the tree and your property. Here are some potential issues to be aware of:
Increased Susceptibility to Disease and Pests: Exposed roots are more vulnerable to infections and infestations, which can weaken the tree over time.
Structural Damage: Roots pushing against sidewalks, driveways, or foundations can cause cracks and instability.
Hazards for People and Equipment: Raised roots create tripping risks and can damage lawnmower blades or other landscaping tools.
If left unchecked, exposed roots may compromise the tree’s health. In extreme cases, a weakened tree can become a safety hazard during storms or dry conditions.
Practical Solutions for Managing Exposed Tree Roots
So, how can you handle exposed tree roots effectively? While cutting the roots might seem like a straightforward fix, it’s actually harmful to the tree and should be avoided. Here are safer and more effective approaches:
Apply a Layer of Mulch
Adding mulch is one of the easiest and most effective ways to manage exposed roots. First, clear the grass around the tree base, then spread a generous layer of mulch over the exposed roots. Mulch acts as a cushion, protects the roots, discourages foot traffic, and eliminates the need for mowing in that area. Opt for shredded or chipped hardwood mulch, but avoid those treated with dyes, as they can harm the tree.
Consider Ground Cover Alternatives
Another approach is to replace grass with a low-maintenance ground cover that doesn’t require mowing. Look for taller ground cover plants that can deter foot traffic. When planting near tree roots, be cautious not to damage the primary roots.
Avoid Adding Extra Soil
It might be tempting to cover exposed roots with more soil, but this is a short-term fix that can lead to bigger problems. Piling soil on top of roots can suffocate them and fail to address the root cause of the exposure. Stick to mulching or ground cover solutions for long-term benefits.
Skip Growing New Grass
Trying to regrow grass over exposed roots can be a frustrating process. Even if the grass takes hold, the roots may resurface over time, especially if the area lacks sufficient sunlight. Consider more sustainable options like mulch or ground cover instead.
Refrain from Cutting Exposed Roots
Pruning tree roots can be detrimental to the tree’s health. Cutting away roots interferes with nutrient and water absorption and may destabilize the tree, increasing the risk of it toppling during severe weather.
Preventing Exposed Tree Roots in the Future
While it’s helpful to know how to fix exposed roots, preventing the problem in the first place is even better. If you’re planting new trees, take these precautions:
Choose the Right Planting Spot: Select a location that allows ample space for the tree’s root system to expand. Large species like oaks and maples require plenty of room to avoid future root exposure.
Understand the Tree’s Needs: Factors such as soil type, moisture levels, and pH influence how roots develop. Research the optimal conditions for your chosen tree species to encourage healthy growth.
Opt for Trees with Less Aggressive Root Systems: Certain tree species are less prone to surface roots. Consult with a landscaping professional if you’re unsure which trees are best suited for your landscape.
