Tree roots naturally go out seeking water, either deep underground or close to the surface depending on its route structure. In cases of dry conditions or trees close to underground piping, gas lines, foundations or electrical lines, the roots can go out of their way to find a bit of water. This usually cause issues with any of the objects interfering with the roots’ search for a water source.

The simplest solution for unwanted root growth is to tame the wild roots with root barriers. Keep reading to learn how root barriers work, how to install them in your garden and where to get the right root barriers for you.

Root barriers – how they help with erosion control for your property

Root barriers keep tree roots from invading soil and depriving other plants of moisture or causing damage to sub-terrain structures. If your garden isn’t thriving as it used to and you notice a nearby massive tree is looking healthier than ever, you should probably take a look beneath the soil.

Tree roots growing in places like under sidewalks can cause the concrete to lift, creating a tripping hazard and potential liability, especially in public spaces. If a tree with untamed root growth is on your property, root barriers can prevent costly damage.

Tree roots are ultimately underestimated for the potential hazards they can cause to properties. They often cause damage that cost hundreds of dollars for repairs. As a solution, a root barrier is built into the ground around the tree to provide a structure so that gas/water lines are protected against tree roots.

This underground wall keeps the roots from conflicting with essential structures and other plants. Root barriers are ultimately the most durable and lightweight solution for controlling unwanted root movement and growth. What’s more, is its material allows the root barrier to be cut and shaped to suit your requirements. Once in place, the barrier creates a long-lasting seal to trap root and moisture. This promotes healthy tree growth without the tree causing damage to surrounding structures.

How to use root barriers in your garden

Soil erosion is one of the biggest threats to all land restoration projects. If left unchecked, erosion could result in damages and financial losses, as well as many hours of hard work, wasted.

An exceptionally effective way of preventing land erosion is to install coir matting.

• Step 1 – Prepare the area
If the tree is new, dig a hole that is twice as wide as its roots. The centre of the hole should be deep enough to hold some enriched soil and the tree root ball so that the depth is the same as the nursery had it planted. Make cuts at the hole’s periphery that are straight-walled two inches less than the root barrier you’re using is deep. Root barrier material come from 12 inches up to 48 inches deep.

• Step 2 – Assemble the root barrier
Assemble the root barrier so that it lines up with the circumference of the hole you created. Place the material in the hole leaving one to two inches of the barrier sticking up above the ground surface after the hole is filled. The root barrier material should be installed as upright as possible.

• Step 3 – Dig up a trench for existing trees
If the root barrier is for existing trees, dig a trench around the trees, which may require cutting back the roots. This is where hiring a professional is suggested since it can take specialized equipment that won’t damage the roots and/or kill the tree.

• Step 4 – Install a linear barrier
If the root barrier is intended to protect a driveway or sidewalk, install a linear barrier along the edge. This will maintain the moisture and nourishment needed to allow the tree roots to continue growing while still effectively redirecting them in more ideal directions.

Best place to find root barriers

The best method for making a root barrier for trees is to call a professional contractor that has experience in this process. Professionals know how far out away from the tree a root grows and how deep to go without damaging the tree. Additionally, specialists know how to find gas and water lines so as not to dig in the wrong place, and they will have the proper equipment.


If you desire to install your own root barrier, you should consult with a tree expert first. They will help ensure that the tree will have access to moisture so that it can survive without the roots damaging your property.
