Roots keep our trees strong, healthy, and grounded—but once they start showing above the surface, they can quickly become a concern. Beyond being an eyesore, exposed tree roots are prone to damage and can cause a variety of problems for you and your tree. 

Fortunately, a certified arborist can help address surface roots and get your tree back in good shape. In this blog, we explain why exposed roots are harmful to your tree’s health and share practical tips for solving the issue.

Why Are Exposed Tree Roots Bad?

Exposed tree roots can cause serious issues for your tree. They may also indicate unseen concerns that already exist. Here are just a few of the problems that surface roots can cause: 

• Tree instability: Roots help anchor a tree to the ground. When they grow above the surface, this support is compromised and the tree is at a greater risk of failure (falling). 
• Root damage: Exposed roots can get stepped on, scalded by the sun, or damaged by landscaping equipment. This can hinder their ability to absorb nutrients for the tree. 
• Vulnerability: Surface roots are more vulnerable to pests and tree diseases, which can compromise the health of the entire tree. 
• Lawn maintenance problems: Exposed tree roots can get in the way of lawnmowing, making lawn care more of a hassle. 

What Makes Tree Roots Grow Above Ground?

There are many reasons why tree roots might grow above the surface: 

• Soil: Poor soil conditions can cause roots to seek oxygen or nutrients above ground 
• Erosion: Erosion from wind, rain, and water runoffs can expose the roots, especially for trees on uneven ground like slopes or hills 
• Overcrowding: There are too many trees nearby, or the space is too small to support healthy root growth 

An experienced arborist can help you identify the underlying cause of the issue. They will also offer solutions to address the surface roots and prevent more from growing above ground in the future. 

How to Deal with Tree Roots in Your Lawn

Surface roots are not only unhealthy for your tree, but can also be an eyesore and a hassle. The good news is, there are steps you can take to solve this issue and help restore your tree to its best condition. 

Cover the Roots with Mulch 

Sometimes, a tree’s roots may grow above ground if it’s not getting enough nutrients or soil. Mulching can address this issue by protecting the roots and boosting soil retention. It also reduces tripping risks and helps the roots absorb more nutrients. 

To mulch over-exposed tree roots, follow these simple steps: 

• Cut back as much grass as you can without damaging the roots to prevent it from growing through the mulch later on. 
• Add the mulch in a ring around the tree without touching the trunk. 1-3 inches should be enough. 
• Avoid over-mulching, which can cause suffocation or root rot. Aim for a “donut” shape instead of a “volcano” or mound.

Plant Low-Maintenance Groundcover 

Another solution is to replace the section of your lawn around the tree with groundcover. This will help protect the roots and discourage walking through that area, which also lowers the risk of trips. 

Consider selecting low-maintenance groundcover plants because these are less likely to outcompete the tree for nutrients. When planting groundcover beneath your trees, be sure to avoid harming the roots in the process. 

Contact a Certified Arborist 

Although tree mulching and installing groundcover can help, you may still want to contact a certified arborist to get valuable insight into the health of your tree. 

Exposed tree roots are often an indicator of a deeper issue, so an arborist can rule out potential problems and identify practical solutions for ensuring the tree’s long-term health. 

One example of a potential solution is installing root barriers. These are underground mechanisms that block roots from growing in certain areas. Arborists may strategically place these barriers to help redirect root growth deeper into the soil.
