Solutions for managing exposed tree roots in lawns

Exposed tree roots in lawns can present challenges for homeowners, but there are solutions available to address this issue while maintaining the health of the trees. Understanding how tree roots function is essential before taking any action.

Tree roots often surface because they require oxygen, similar to grass. They typically reside within the top 4-15 inches of soil. Covering them with excessive soil can be detrimental and potentially kill the tree.

One approach is covering exposed roots with a thin layer of soil and seeding the lawn. However, this method is not a long-term solution as repeated mowing may eventually expose the roots again.

A more sustainable option involves creating a mulched garden bed around the tree's base by removing sod from around the roots. This not only provides an aesthetically pleasing landscape but also supports local ecosystems by planting ground covers and perennials that benefit pollinators.

Cutting exposed roots requires caution and adherence to specific guidelines to avoid harming the tree. Davey Tree Experts suggest pruning only those roots that are five times the diameter away from your tree. Todd Marieta advises against removing more than 25% of a tree's root mass and suggests waiting two years before trimming them back again if necessary.

When removing roots, it's important to maintain balance by breaking up root mass into four quadrants and ensuring equal removal from opposing sides. Large roots should generally remain untouched as they contribute significantly to structural integrity.

Frequently asked questions include concerns about damage to lawnmowers when mowing over exposed roots, which can harm both equipment and trees. Species like maples, oaks, and willows are more prone to having shallow root systems that lead to exposure. Signs such as yellowing leaves or slow growth may indicate stress caused by exposed roots; consulting a professional arborist is recommended in these cases.

To prevent future exposure issues, regular mulching combined with proper care practices like deep watering can help maintain healthy root systems over time.

In summary: managing exposed tree roots effectively involves either temporarily covering them with soil or creating permanent mulched beds while adhering strictly following guidelines when cutting problematic ones – all aimed at preserving overall health without compromising safety or aesthetics within landscapes where they exist today!
