Cutting large roots can weaken a tree’s hold on the ground and reduce its ability to take up water. Depending on how many are cut and where, the effects range from mild stress to decline or a greater chance of the tree tipping over.
Effects on Stability
Large roots near the trunk act like anchors. When several are cut on one side, the tree may have less support against wind pushing from the other direction. A tree can look perfectly normal after root cutting while having lost some of that support below ground.
That’s why damage to large roots isn’t something anyone should judge from a photo or from what’s visible above the soil alone.
Soil conditions can make things worse. Soaked ground after heavy rain gives any remaining roots less grip.
Effects on Tree Health
Losing one big root also means losing all the smaller roots attached to it. Over time, the tree may show:
- Leaves that wilt, yellow, or drop early, especially in summer heat
- Thinning in the part of the canopy above the cut roots
- Branches dying back over the following seasons
- Decay entering through the cut ends
These signs don’t always appear right away. Stress from root loss can show up months or even a few years later, which makes it hard to connect cause and effect.
Species and age both play a part. A young, vigorous tree may cope better with some root loss than an older tree already stressed by drought, heat, or earlier construction.
Effects on the Area Around the Tree
Root cutting changes more than the tree. Removing thick roots from under a slab or path can leave loose soil or gaps that settle later. Digging near a large tree can also disturb nearby lawn, beds, and irrigation lines, adding repair work of its own.
Construction is a common culprit. Trenching for utilities, pouring a new patio, or widening a driveway can cut roots without anyone noticing until the tree starts to struggle.
Plan Before Anything Is Cut
If large roots are in the way of a project or repair, it’s better to plan before cutting. Root removal done with the tree in mind looks at which roots matter most and whether the goal can be met with less cutting. Sometimes the answer is to adjust the project. Other times, the tree can’t safely lose those roots, and removal needs to be discussed.
