Exposed Tree Roots: Why Adding More Soil is not a Good Idea

You might feel tempted to either cut or cover tree roots that are exposed on your property. You might be tempted to do either of these things, but it can cause a bigger problem for the tree and you.

This article explains why exposed tree roots should not be cut or how to add soil over them. Either of these actions could result in severe damage to your tree. We also discuss here the ways to repair exposed tree roots without having to cut or cover them.

The dangers of cutting roots

There are several reasons why cutting tree roots exposed can be a problem.

• Injure the tree: Cutting the roots of your tree could cause damage to the tree, causing it to become unhealthy. A damaged or dead tree in your property should be a concern. This could cause property damage, injury, or even death. To determine if a tree on your property is in danger of dying or has suffered damage, call a professional arborist.

• Tree dying: Cutting exposed roots can cause enough damage, thus causing the tree to die. You may not be able to see the root system underground, so you could be cutting a primary root which provides nutrients to the tree. The chances of the tree living will be reduced if this happens.

• Tree instability: Unstable trees pose a threat to property and people. Unstable trees can also cause property damage and even death, just like an injured tree. This is particularly true in areas that are subject to extreme weather conditions. It is important to prune your trees regularly.

• Reduces nutrients for the tree: A root that is cut could be a significant source of nutrients and water. The tree's vital supply of nutrients and water will be cut off if the root is exposed. This will eventually make it sick, unstable, and unsafe.

Problems with Adding more soil

It is not the solution to add more soil.

• Don't ignore the root cause. Tree roots are built to grow under the soil. If you find tree roots on your property, it could indicate a larger problem, such as soil erosion.

• Reduces nutrients for trees: Tree roots can be prevented from getting the right amount of oxygen by covering them with soil. This could be the reason roots reached the surface in the first place.

How to deal with exposed tree roots

• Mulch or compost can be used to cover exposed roots: Mulch is lighter than soil and therefore does not suffocate the roots. Another ground cover can be used over exposed roots. You can also use compost as it is lighter and has larger pore space, allowing oxygen to penetrate deeper into the soil. This is a medium for planting groundcover such as Pachysandra, Ivy, Jasmine, and Vinca Minor. Make sure that the groundcover you choose does not smother the root.

• Limit access to the area: Another option is to limit or cut off access to the root(s) exposed. This will reduce the chance of the root becoming damaged or someone tripping over it.

• Add foliage: It is possible to plant shrubs or plants near the root(s), and other options are available. This will reduce foot traffic and conceal any exposed roots. You should avoid plants that attract deer, as they could cause additional problems for you.
