Large trees add shade, privacy, and character to a property, but they can also become serious hazards when they start declining. In Metro Atlanta, heavy rain, saturated clay soil, summer storms, and high winds put a lot of stress on aging trees throughout the year.
The challenge is that many dangerous trees do not always look dead at first glance. A tree may still produce leaves while hiding major structural problems inside the trunk or root system.
Knowing what warning signs to watch for can help you catch problems early before a damaged tree falls onto a home, driveway, fence, or power line.
1. Mushrooms or Rot Around the Base of the Tree
Mushrooms growing near the trunk are not always a problem by themselves. But large fungal growths attached directly to the tree or surrounding the base can point to internal decay.
These fungi feed on rotting wood inside the trunk or root system. In many cases, the tree may already be hollow or structurally weakened underneath the bark.
Watch for:
- Soft or crumbling wood near the base
- Large shelf-like fungi attached to the trunk
- Hollow areas or cavities
- Sections that stay wet or dark long after rain
A tree with significant internal decay may not have enough strength to withstand strong winds or saturated ground conditions.
2. Deep Cracks or Large Cavities in the Trunk
Small surface cracks in bark are common on older trees. Deep splits running into the trunk are different.
Vertical cracks can develop after storm damage, temperature swings, or years of structural stress. Once the trunk begins separating, the tree becomes much less stable.
Large hollow cavities are also a concern, especially where major limbs connect to the main trunk.
Pay close attention if you notice:
- Deep vertical splits
- Open cavities collecting water
- Large dead sections near major branch joints
- Multiple cracks forming on the same trunk
Some trees can live with minor hollow areas for years. Others become dangerous quickly depending on the location and depth of the damage.
3. The Tree Suddenly Starts Leaning
Most trees naturally grow with a slight lean over time. What matters is whether the lean is new or getting worse.
A tree that suddenly shifts position after heavy rain or storms may have root damage underground. In Metro Atlanta’s clay-heavy soil, saturated ground can loosen weakened root systems surprisingly fast.
Warning signs of root failure include:
- Cracked or lifted soil near the base
- Exposed roots pulling out of the ground
- Fresh leaning after storms
- Soil mounding on one side of the trunk
If the root plate starts moving, the tree may no longer be stable enough to remain standing safely.
4. Large Dead Branches in the Upper Canopy
A few dead branches are normal in mature trees. When large sections of the canopy stop producing leaves, it often signals a bigger health issue.
This condition, commonly called dieback, usually means the tree is struggling to move water and nutrients properly through the trunk and roots.
You may notice:
- Bare limbs during growing season
- Bark peeling off large branches
- Brittle limbs snapping easily
- Sudden leaf loss in major sections of the canopy
Dead limbs become especially dangerous during storms because they can break off without much warning.
5. Weak Multi-Trunk Growth or Splitting Stems
Some trees grow with two or more main trunks connected at a narrow angle. These are called co-dominant stems, and they are one of the most common structural problems arborists see after severe weather.
As the trunks grow larger, they push against each other instead of forming one strong connection. Over time, bark becomes trapped between the stems, creating a weak separation point.
These trees are more likely to split during:
- high winds
- heavy rain
- ice accumulation
- saturated soil conditions
A large split between trunks can happen suddenly and often causes major property damage when it does.
Not Every Damaged Tree Needs Removal
One important thing homeowners should know is that removal is not always the only option.
Some trees can be stabilized through:
- strategic pruning
- cabling or bracing
- weight reduction
- disease management
- root zone care
That is why professional evaluation matters before making a final decision. The goal is not to remove healthy trees unnecessarily, but to identify when a tree has become unsafe or structurally unreliable.
When to Schedule a Professional Tree Assessment
If a tree has started leaning, dropping large limbs, developing trunk decay, or showing signs of root failure, it is worth having it inspected before the next major storm moves through the area.
