Seven Warning Signs a Tree May Be Dangerous

Would You Recognize a Dangerous Tree?

Trees can look healthy from a distance while hiding serious structural problems. Cracks, decay, damaged roots, and weak branch connections can make a tree more likely to fail during strong winds or heavy rain.

Recognizing the warning signs early may help prevent property damage, personal injury, and an unexpected tree emergency. Here are seven signs that a tree on your property may need professional attention.

1. Cracks or Splits in the Trunk

A visible crack can indicate that the trunk is beginning to separate or can no longer support the weight above it. This is especially concerning on trees with multiple trunks or a narrow V-shaped connection.

Fresh cracks, exposed wood, peeling bark, or a split that appears to be growing should not be ignored. Keep people, pets, and vehicles away from the area until the tree can be evaluated.

2. Dead or Hanging Branches

Dead branches may remain suspended in the canopy long after they have stopped producing leaves. These limbs can fall without warning, even during calm weather.

Look for branches without leaves during the growing season, peeling bark, brittle wood, and broken limbs hanging in nearby branches. Limbs located over a roof, driveway, sidewalk, playground, or gathering area create an increased risk.

3. A Tree That Suddenly Starts Leaning

Some trees naturally grow at an angle and remain stable for many years. A new or increasing lean is different and may indicate damage to the roots or movement in the surrounding soil.

A leaning tree is especially concerning when accompanied by cracked soil, raised ground, or exposed roots on the opposite side. Saturated soil after heavy rainfall can make an unstable tree even more likely to uproot.

4. Hollow Areas, Cavities, or Decay

Trees can sometimes continue growing around hollow or decayed sections, but extensive internal damage may weaken the trunk or large branches.

Watch for cavities, missing bark, soft or crumbling wood, large wounds, and areas that appear dark or rotten. Because much of the decay may be hidden inside the tree, the visible damage may only show part of the problem.

5. Mushrooms or Fungal Growth

Mushrooms growing from the trunk, roots, or ground near the tree can sometimes indicate decaying wood beneath the surface.

Not every mushroom means the tree is dangerous, but fungal growth combined with a thinning canopy, cavities, dead branches, or root damage deserves attention. Removing the visible mushrooms does not correct any decay inside the tree or root system.

6. Damaged or Lifting Roots

Roots anchor the tree and help it resist strong winds. Construction, trenching, erosion, flooding, soil compaction, and heavy equipment can damage them.

Look for cut roots, lifting soil, cracks around the tree’s base, exposed roots, or a root plate beginning to rise. Root problems can be especially dangerous because the entire tree may fall rather than losing only one branch.

7. Weak Connections Between Multiple Trunks

Trees with two or more main trunks can develop weak connections where the trunks meet. Bark trapped inside a narrow union can prevent the trunks from forming a strong attachment.

Cracking, separation, dark lines, or exposed wood between the trunks may show that the connection is beginning to fail. As each trunk becomes larger and heavier, the pressure on that weak point increases.

What Should You Do If You Notice These Signs?

Do not attempt to climb, cut, pull, or brace a questionable tree yourself. Trees and branches under pressure can move unexpectedly, and work involving ladders, chainsaws, buildings, or utility lines can be extremely dangerous.

Move vehicles and outdoor belongings away from the area, keep people and pets at a safe distance, and arrange for a professional evaluation.

If a tree or branch is touching a utility line, stay away and contact the utility company immediately.
