Invasive Tree Roots: A Problem for Homeowners and Businesses
Introduction
Tree roots can be a big problem for homeowners and businesses. They can interfere with streets and sidewalks, sneak into septic lines, and cause trip hazards. And even if you remove the tree, the stump or remaining roots may continue to grow. That’s why it’s important to understand tree root systems and how to deal with root problems.
Understanding Tree Root Systems
Trees use their roots to anchor themselves in the ground and to absorb water and nutrients. The type of root system a tree has depends on the species of tree and the soil conditions. Some trees have shallow roots that spread out near the surface of the ground, while others have deep roots that can reach down several feet. Some trees have a single taproot that grows straight down, while others have a network of smaller roots that spread out in all directions.
Tree Root Problems
Tree roots can cause a variety of problems, including:
- Damage to sidewalks, streets, and driveways: Tree roots can crack and lift sidewalks, streets, and driveways, creating a tripping hazard.
- Clogged drains and sewers: Tree roots can grow into drains and sewers, causing them to clog and back up. This can lead to flooding and other problems.
- Damage to building foundations: Tree roots can also damage building foundations, especially if the tree is planted too close to the building.
- Tree root suckers: Some trees send out suckers, which are new shoots that grow from the roots. Suckers can quickly spread and create a dense thicket of trees, which can be difficult to control.
Problem Tree Roots and Planting
The best way to avoid tree root problems is to choose the right tree for the location. If you’re planting a tree near a sidewalk, driveway, or building, choose a tree with a shallow root system. You should also avoid planting trees that are known to produce suckers.
How to Control Invasive Roots
If you already have a tree with invasive roots, there are a few things you can do to control them:
- Tree removal: In some cases, the only way to solve a tree root problem is to remove the tree. However, this is a last resort, and should only be considered if the tree is causing significant damage.
- Stump grinding: If you remove a tree, be sure to grind the stump to prevent the roots from continuing to grow.
- Root barrier: You can install a root barrier around a tree to prevent the roots from spreading. Root barriers are available in a variety of materials, including plastic, metal, and fabric.
- Root pruning: In some cases, it may be necessary to prune the roots of a tree to control their growth. This should only be done by a qualified arborist.
Conclusion
Tree root problems can be a nuisance, but they can also be a serious hazard. By understanding tree root systems and how to deal with root problems, you can protect your property and keep your trees healthy.
