Tree roots may grow silently underground, but over time, they can cause loud and costly problems. From cracking driveways to threatening home foundations, unchecked root growth is one of the leading causes of structural damage in residential and commercial landscapes—especially in South Louisiana, where clay soils and water tables can intensify the issue.
What Is Root Trimming?
Root trimming, also called root pruning, is the strategic cutting of tree roots to prevent them from damaging nearby structures. Certified arborists use specialized tools and techniques to remove specific roots—usually those growing too close to foundations, walkways, driveways, or underground utilities—without compromising the health of the tree.
Why It’s Necessary
-
Protecting Foundations: Roots can slowly infiltrate the foundation of a home, displacing soil and causing cracking or shifting over time.
-
Saving Driveways and Sidewalks: As roots expand, they push against concrete and asphalt surfaces, causing dangerous lifts and cracks.
-
Preventing Sewer and Pipe Intrusion: Some aggressive roots seek out moisture and can invade plumbing lines, leading to costly repairs.
-
Improving Tree Health: Ironically, selective root trimming can also improve tree stability and redirect energy to more productive root zones.
When and How It’s Done
A proper root trimming service involves careful planning and usually includes:
-
Root Mapping: To identify which roots pose a threat and which are vital to the tree’s survival.
-
Clean Cuts: Using sharp, professional-grade tools to ensure minimal trauma to the root system.
-
Barrier Installation: After pruning, some services include installing root barriers to prevent regrowth in unwanted directions.
-
Timing: Ideally performed during dormancy (late fall or winter), root trimming at the right time reduces stress on the tree.
Why You Shouldn’t DIY It
Cutting the wrong roots can kill a tree or make it unstable in a storm. In hurricane-prone regions like South Louisiana, improper root pruning can turn a healthy tree into a falling hazard. Professional arborists know how to balance protection for your property and the health of your trees.
The Bottom Line
Root trimming is not about chopping blindly—it’s about protecting your biggest investments: your home, your driveway, and your peace of mind. When done right, it’s a win-win for you and your trees.
