7 Warning Signs a Tree May Fall and What to Do Next

A tree that may fall often shows changes in its lean, roots, trunk, major limbs or canopy. A new lean, lifted soil, a widening trunk crack, hanging branches, large cavities, mushrooms near the base or sudden dieback all deserve attention, especially when the tree could reach a home, driveway, road, vehicle or occupied area.

These are signs it’s time for it to be evaluated. If the tree is moving, splitting, uprooting, touching electrical lines or dropping large limbs, keep everyone away and treat it as an emergency.

This is especially important during the stormy summer months in Habersham County and across Northeast Georgia. Heavy rain can soften saturated soil while wind places more force on a full canopy, exposing weaknesses that were difficult to see in calm weather.

What Makes a Tree Dangerous?

A tree becomes dangerous when it has a meaningful chance of failure and people or property are within reach. Arborists call a home, driveway, vehicle, power line, walkway or occupied space below the tree a target.

1. The Tree Has a New or Worsening Lean

Many healthy trees grow with a natural lean. The concern is a tree that begins leaning after wind, heavy rain, flooding, excavation or soil movement, or one whose lean has noticeably increased.

From a safe distance, look for cracked soil, exposed roots or a root plate beginning to lift. A recent lean is more urgent when the tree could reach a building, road or occupied area. If the tree shifted recently or the soil is moving, clear the area and request immediate help.

2. The Trunk Is Cracked, Split or Separating

Watch for a crack that extends into the wood, opens under wind, produces fresh splinters or causes sections of the tree to separate.

Not every bark seam is a structural crack. However, a widening split in a load-bearing area can change quickly. If you hear cracking, see active movement or notice a major stem separating, leave the fall zone and call for emergency assistance.

3. Large Branches Are Dead, Broken or Hanging

Large broken branches can remain caught in the canopy or suspended in neighboring trees. Dead limbs may stay attached until wind, rain or decay causes them to fall.

Never stand beneath a hanging branch or pull it with a rope. Storm-damaged wood can hold hidden tension, and moving one part can release another without warning.

4. The Trunk or Root Flare Has Cavities, Soft Wood or Mushrooms

Large cavities, hollow areas, cankers and soft or crumbling wood may indicate lost structural material. Mushrooms or shelf-like fungal growth on the trunk, root flare or soil near the base can be signs of internal decay.

Mushrooms cannot reveal how much sound wood remains or when a tree could fail. Request an arborist assessment rather than probing the cavity or attempting a strength test.

5. The Canopy Shows Significant Dieback

Look at the entire crown rather than one leaf or twig. A thinning canopy, dead branch tips, sections that fail to leaf out, brown needles at the top during the growing season or repeated premature leaf drop can signal root problems, disease, decay or long-term stress.

Dieback does not mean a tree is about to fall, but decline concentrated on one side may correspond with root injury or trunk damage.

6. Major Stems Have a Weak Union

Some trees develop dominant stems that meet at a narrow angle. Bark can become trapped between them instead of forming a strong connection that withstands wind.

Warning signs include an opening seam, decay or dampness in the union, fresh cracking, independent movement or a previous failure on the opposite side. Depending on the tree, pruning, cabling, bracing, monitoring or removal may be considered.

7. The Roots or Surrounding Soil Were Disturbed

Trenching, grading, compaction, erosion and construction equipment can damage roots even when the trunk looks normal. Watch for cut roots, soil piled against the trunk, changed drainage or equipment traffic within the root zone. Damage may appear immediately or years later.

When Is a Dangerous Tree an Emergency?

Call for urgent assistance when the tree creates an active or immediate threat:

  • The tree suddenly moved or began leaning after wind, rain or soil movement.
  • Roots are lifting, the root plate is moving or the surrounding soil is cracking.
  • The trunk or a major union is actively splitting.
  • A large limb is hanging over a home, driveway, road, vehicle or occupied area.
  • The tree has fallen on a structure or is blocking the only safe access.
  • The tree or a broken limb is touching electrical lines.
  • Sections of the tree are suspended in neighboring trees or shifting under load.

For an active hazard, move people and pets away and call McAllister’s 24/7 emergency tree service at (706) 778-7527. If electrical lines are involved, assume they are energized and contact the utility provider or emergency services from a safe location.

When Should You Schedule an Arborist Assessment?

Schedule an assessment for gradual lean, canopy decline, cavities, fungal growth, weak forks, recurring dead limbs or construction damage, especially when the tree can reach a structure or frequently used area.

McAllister’s arborist services can help determine whether the next step is pruning, monitoring, added support, site changes or professional tree removal. The goal is to understand the condition and reduce risk, not to remove every imperfect tree.

Can a Dangerous Tree Be Saved?

Sometimes. A tree may be preserved when its roots and trunk are stable, damage is limited and enough healthy canopy can remain. Options include pruning, added support or monitoring.

Removal becomes more likely when the root plate has moved, the trunk is splitting, advanced decay affects a critical support area, several major limbs have failed or corrective pruning would leave the tree unbalanced. The decision should consider the entire tree and site.

What to Do After a Storm

  • Wait until conditions are safe. Do not inspect trees during lightning, strong wind or falling debris.
  • Keep people out of the fall zone. Move vehicles only when they can be reached without walking beneath damaged trees or limbs.
  • Look from a safe distance. Note new lean, lifted roots, trunk cracks, hanging branches and contact with structures or utilities.
  • Photograph only what you can reach safely. Wide images can help with triage and documentation.
  • Call the appropriate professional. Use emergency service for active threats and schedule an arborist assessment for non-urgent concerns.

Frequently Asked Questions

Does a leaning tree always need to be removed?

No. Some trees grow safely with a natural lean. A new or increasing lean with lifted roots, soil cracks, decay at the base or a target in the fall path is more concerning.

Do mushrooms mean a tree is going to fall?

Not necessarily, but mushrooms on the trunk, root flare or near the base can indicate wood-decay fungi. A professional should evaluate how the decay may affect the tree’s strength.

Can I remove a hanging limb myself?

Large hanging branches and storm-loaded wood can move suddenly when cut. Keep away from the area and call a trained, insured tree-care professional.

Who should I call if power lines are involved?

Stay well away and treat every contacted line as energized. Contact the utility provider or emergency services. Tree work should begin only after the electrical hazard is addressed.
