Trees add beauty and value to a property, but when they become unstable or unhealthy, they can pose a serious safety risk. A hazardous tree can cause property damage, injuries, or even fatalities if it falls unexpectedly. Knowing the warning signs of a dangerous tree can help you take action before disaster strikes. If you notice any of these signs, it’s best to have a professional arborist inspect the tree for potential removal or corrective care.
1. Large Dead or Hanging Branches
Dead, broken, or hanging limbs can fall at any time, especially during storms or high winds. These branches may be partially detached but still caught in the tree’s canopy.
What to Look For:
- Large, dry, or brittle branches that lack leaves.
- Branches with cracks, splits, or missing bark.
- Limbs that appear ready to fall but are still tangled in the tree.
Ignoring dead branches increases the risk of property damage or personal injury.
2. Leaning or Unstable Trunk
A tree that is leaning significantly or has suddenly shifted position could be at risk of falling. Some trees naturally lean, but a recent, unnatural tilt may indicate root damage or structural instability.
Warning Signs:
- A sudden lean after a storm or high winds.
- Cracked soil or uprooting near the tree’s base.
- Exposed roots that appear damaged or decaying.
If the tree leans toward your home, driveway, or a power line, it may need immediate removal.
3. Cracks or Splits in the Trunk
Deep cracks, cavities, or splits in the trunk weaken the tree’s structure, increasing the risk of breakage. Severe trunk damage may compromise the tree’s ability to stay upright.
How to Identify Trouble:
- Long vertical cracks or deep splits in the bark.
- Large cavities or hollow sections in the trunk.
- Signs of decay, fungal growth, or insect infestation inside the cracks.
A compromised trunk can lead to total tree failure, especially in extreme weather conditions.
4. Weak or Decayed Roots
A tree’s root system provides stability, and any damage to the roots can make it more likely to fall. Root problems may not be visible above ground, but there are signs that indicate underground issues.
Signs of Weak Roots:
- Mushrooms or fungal growth at the base of the tree.
- The tree is easily swaying in the wind.
- Uplifted soil or exposed roots.
Trees with compromised roots are often beyond saving and should be removed before they collapse unexpectedly.
5. Signs of Disease or Decay
A sick or dying tree weakens over time, making it more likely to become a hazard. Trees affected by disease or rot may have internal decay, reducing their structural integrity.
Symptoms of Disease or Decay:
- Fungal growth (such as mushrooms or conks) on the trunk or branches.
- Discolored or wilting leaves, even in the growing season.
- Large sections of missing bark or peeling bark.
- Holes in the wood, often caused by insects or woodpeckers.
A diseased tree won’t recover on its own, and in many cases, removal is the safest option.
6. Close Proximity to Structures or Power Lines
Even a healthy tree can become a hazard if it grows too close to homes, fences, driveways, or power lines. During storms, high winds can cause branches to break off or bring down the entire tree.
Potential Risks:
- Branches touching or overhanging your home.
- Trees near driveways or sidewalks, posing a risk to pedestrians.
- Limbs growing into power lines, increasing fire hazards.
If a tree is too close to a structure, professional trimming or removal may be necessary.
7. Excessive Shedding or Dead Leaves
A tree that loses leaves, bark, or small branches excessively outside of its normal seasonal cycle may be struggling to survive.
Warning Signs:
- Leaves turning brown and falling early in the year.
- Dead branches shedding frequently.
- Large amounts of bark peeling off the trunk.
These symptoms could indicate a dying tree that may soon become a safety hazard.
Final Thoughts
Trees enhance your property, but when they become unstable, diseased, or structurally weak, they pose a significant risk. If you notice cracks in the trunk, dead branches, leaning trees, or root damage, it’s best to call a professional tree service for an inspection. Early detection and preventative care can keep your property safe and help you determine if the tree needs trimming or removal before it causes harm.
