Digging Deeper into the Roots of a Neighboring Issue...
/What Happens When Tree Roots Cross Property Lines?
We recently talked about general responsibility around neighboring trees, and the topic piqued quite a bit of interest. For good reason, too, as this is a common situation many homeowners encounter. Most people think about the branches they can see, but a tree’s roots can create just as many questions.
Concerns often arise when neighboring tree roots begin affecting lawns, landscaping, sidewalks, or driveways. The challenge is that tree roots don’t simply stop at property lines. In fact, they often spread well beyond a tree’s canopy in search of water and nutrients.
Why Are Tree Roots So Close to the Surface?
Many people assume tree roots grow deep into the ground. However, according to Purdue Extension, most tree roots tend to grow much more shallowly than most people think – usually only 4-8 inches deep. These shallow roots allow trees to access oxygen, water, and nutrients more efficiently.
Because roots grow outward rather than downward, they can eventually surface in lawns, interfere with landscaping projects, and even impact sidewalks, patios, and driveways.
Can You Cut Roots That Cross onto Your Property?
In many situations, property owners have the right to address roots that encroach onto their property. However, cutting large roots can have unintended consequences. This is especially true for mature trees, where root damage may not become obvious until months or even years later. Removing significant roots may reduce a tree’s stability, increase stress on the tree, lead to decline over time or create potential safety concerns.
This is especially true for mature trees, where root damage may not become obvious until months or even years later. It’s important to note, not every exposed root or cracked sidewalk signals a major problem.
However, it may be time to consult a professional if you notice:
Large roots lifting sidewalks or driveways
Significant root exposure above the soil surface
Sudden decline in a nearby tree
Construction or landscaping projects near mature trees
Friendly reminder: Tree roots naturally extend beyond property lines, which can sometimes create challenges between neighbors. Before cutting roots or beginning a landscaping project near a mature tree, it’s worth understanding how the root system may be affected.
A little planning today can help prevent costly repairs, tree decline, or safety concerns in the future.
