Homeowners often notice tree roots emerging above the soil surface and worry that something may be wrong. However, according to Kansas State University Extension horticulture expert Matthew McKernan, exposed roots are often a natural part of tree growth and do not necessarily indicate poor tree health.
Many people assume tree roots should grow deep underground, but most roots actually develop near the soil surface where water, nutrients and oxygen are most abundant. Because these essential resources are concentrated in the upper soil layers, roots naturally spread outward rather than downward.
Soil conditions also influence root growth. Compacted or poorly aerated soils can limit deeper root development, causing roots to remain closer to the surface. Older trees and species such as silver maples, poplars and willows are especially likely to develop shallow root systems.
While exposed roots are usually normal, they can sometimes point to soil-related challenges. Excessive root exposure may indicate compacted or overly wet soils that restrict oxygen availability, making it important to monitor both soil conditions and overall tree health.
Surface roots can create practical issues around landscapes and yards. One of the most common concerns is the risk of trips and falls, especially when roots rise above surrounding ground level. Rather than cutting roots, homeowners are encouraged to improve their visibility or protect them with mulch.
Lawn maintenance can also become more difficult when roots are exposed. Mower blades that strike roots may damage both equipment and the tree, increasing the risk of disease. Mulch or low-maintenance ground covers can help shield roots while reducing mowing needs.
In some situations, expanding roots can affect nearby structures. Sidewalks, driveways and paved areas may crack or become uneven as roots grow beneath them, and significant damage may require professional assessment.
Damaged roots are often more vulnerable to pests and diseases. Injuries caused by lawn equipment can create entry points for insects and pathogens, potentially weakening the tree and reducing its long-term health.
Homeowners should also watch for signs of tree stress beyond exposed roots. Slow growth, thinning canopies, unusual leaf discoloration and bark damage can all indicate underlying problems related to soil conditions, nutrient deficiencies, pests or disease.
Although visible roots are often a normal characteristic of mature trees, monitoring tree health and maintaining good soil conditions can help prevent more serious issues. With proper care, trees with exposed roots can continue to grow and thrive for many years.
