What to Do About Exposed Tree Roots: Understanding the Issue and Taking Appropriate Action

1. Soil Erosion:
   One of the primary reasons for exposed tree roots is soil erosion. The natural movement of water over time can wash away the surrounding soil, leaving the roots exposed and vulnerable.
2. Compacted Soil:
   Urban environments, construction, foot traffic, and heavy machinery can lead to compacted soil around trees. This reduces the ability of roots to spread and forces them to grow upward, seeking oxygen and nutrients.
3. Improper Mulching:
   Excessive mulching, especially piled against the trunk, can cause roots to grow upward instead of spreading horizontally, leading to surface exposure.
4. Tree Age and Species:
   Older trees and certain tree species are more prone to developing exposed roots as they grow and expand their root systems.

1. Root Suffocation:
   Roots need oxygen to survive. Covering them with soil or other materials may suffocate the roots and harm the tree.
2. Stress on the Tree:
   Cutting away exposed roots can cause significant stress to the tree. These roots are essential for stability and nutrient absorption.
3. Tree Instability:
   Removing large roots can destabilize the tree, making it more susceptible to falling during storms or high winds.

1. Consult an Arborist:
   If you notice exposed roots on your tree, the first step should be to consult a certified arborist. They will assess the situation, identify potential risks, and recommend appropriate actions based on the tree's health and condition.
2. Mulch Properly:
   If the exposed roots result from excessive mulching, clear the mulch away from the tree's base. Leave a few inches of space between the trunk and mulch, allowing the roots to spread naturally.
3. Install a Root Barrier:
   In cases where soil erosion is the main issue, consider installing a root barrier. These barriers help retain the soil around the tree's roots and prevent further erosion.
4. Build a Raised Bed:
   For trees with extensive root exposure and soil erosion, constructing a raised bed around the tree can be a viable solution. Fill the bed with well-draining soil, ensuring the roots have the necessary space to grow and spread.
5. Implement Erosion Control Measures:
   In areas prone to soil erosion, implement appropriate erosion control measures, such as terracing or installing drainage systems, to redirect water flow and protect the tree's roots.
