A falling tree can cause thousands of dollars in property damage and pose serious safety risks. Knowing the signs of an unstable tree can help you act before disaster strikes. If you live in Pennsylvania, New Jersey, or Delaware, storm seasons and heavy winds make proactive tree care even more important.
In this guide, we’ll walk you through the top warning signs a tree may fall—and how to handle it safely.
Why Trees Fall: Common Causes
Before spotting the signs, it helps to understand why trees fall:
- Storm damage: High winds, heavy snow, or lightning can weaken or split branches.
- Root damage: Construction, erosion, or disease can destabilize the root system.
- Age and decay: Older trees are more vulnerable to internal rot and hollowing.
- Soil conditions: Loose or waterlogged soil can cause trees to lean or shift suddenly.
7 Warning Signs a Tree Might Fall
1. Noticeable Lean
A tree that’s leaning more than 15 degrees should be inspected immediately. A gradual lean could be natural growth, but sudden or increasing tilt is a red flag.
2. Cracked or Heaving Soil at the Base
If the soil around your tree looks disturbed—especially after a storm—it may indicate root system failure or uprooting in progress.
3. Dead or Hanging Branches
Large, dead limbs (especially in the upper canopy) can fall without warning and suggest the tree is stressed or dying.
4. Deep Cracks or Cavities in the Trunk
Vertical splits, hollow trunks, or large open wounds may weaken structural integrity and signal internal decay.
5. Fungi Growing Around the Base
Mushrooms or fungal growth around the trunk can indicate rot inside the tree or root system—both of which increase fall risk.
6. Excessive Leaf Loss or Sparse Canopy
Trees that drop leaves out of season or develop bare patches may be suffering from disease or pest damage.
7. Branches Crossing or Rubbing Together
This weakens bark and creates entry points for decay. Over time, it can destabilize the tree's balance.
What to Do If You See These Signs
- Avoid the area beneath or near the suspect tree, especially during high winds.
- Call a licensed arborist or tree service for a professional evaluation.
- Don’t attempt removal or trimming on your own, especially if power lines are nearby.

FAQs
How do I know if a tree is dead or just dormant?
Scratch a small section of bark. If it’s green underneath, the tree is likely alive. No green means the limb may be dead or the entire tree could be compromised.
Should I remove a leaning tree immediately?
Not always—but if the lean is sudden, worsening, or near a structure, it should be evaluated as soon as possible.
Can a tree fall without warning?
Yes. While many trees show signs, others—especially during storms—can fall suddenly. That’s why proactive inspection is crucial.
