The Hidden Danger in Your Yard: Why Hollow Trees Are a Serious Safety Risk

You might walk past it every day—an old tree that looks strong enough on the outside, but inside it's rotting away. Hollow trees are a lot more common than most people realize, and they can be ticking time bombs in your yard.

At Forrester Tree Services, we regularly inspect and remove hollow trees across Clarksville, TN, and here's what every homeowner should know.

Hollow Trees Can Still Look Alive

One of the biggest misconceptions is that a hollow tree is always a dead tree. Not true. Trees can continue to grow and produce leaves even while their core is rotting. That’s because the living part of a tree—the cambium layer—is just beneath the bark. So a tree can appear green and vibrant while the interior is structurally unsound.

Why Hollow Trees Are Dangerous

The biggest risk is failure under stress. That could mean:

• Falling during high winds

• Snapping under snow or ice loads

• Dropping large limbs without warning

• Uprooting due to root rot that goes undetected

When a hollow tree is near your home, driveway, play area, or fence line, the stakes are high. Storms don't ask for permission, and cleanup after a collapse can cost far more than a preemptive removal.

Warning Signs to Look For

• Cavities or large holes in the trunk

• Fungal growth or mushrooms at the base

• Cracks, splitting, or bark separating from the trunk

• Signs of carpenter ants, bees, or woodpeckers

• Leaning toward structures or high-traffic areas

What to Do If You Suspect a Tree Is Hollow

Don’t grab a chainsaw and start cutting—hollow trees can be unpredictable and dangerous to remove without the right equipment. Call in a professional to inspect the tree first. At Forrester Tree Services, we’ll give you a clear assessment of the risk and a safe removal plan if needed.
