Tree Trunks: What Their Condition Reveals About Tree Health

Tree trunks often reveal early warning signs of decay, disease, pests, and structural instability. Cracks, cavities, peeling bark, mushrooms, and sudden leaning are common indicators that a tree may be unsafe and should be evaluated by a certified arborist.

Tree Trunks: What Their Condition Reveals About Tree Health in West Hartford, CT

Tree trunks often reveal early warning signs of decay, disease, pests, and structural instability. Cracks, cavities, peeling bark, mushrooms, and sudden leaning are common indicators that a tree may be unsafe and should be evaluated by a certified arborist.

Most homeowners focus on branches and leaves when assessing tree health—but the tree trunk is one of the most important indicators of whether a tree is healthy, stressed, or becoming dangerous. At ALX Tree Service, we inspect thousands of trees across West Hartford, Windsor, Bristol, Glastonbury etc. every year and almost every major issue can be detected early just by looking at the trunk.

Below is a breakdown of what different conditions can tell you—and when it’s time to call in a professional to prevent property damage.

1. Cracks in the Tree Trunk

Vertical cracks, deep splits, or seams usually signal internal stress.

Possible causes:

• Sudden temperature swings

• Storm damage

• Weak branch unions

• Internal decay

Why it matters:

A cracked trunk compromises stability. Even a small fissure can become a failure point during a storm or heavy winds.

2. Cavities or Holes in the Trunk

Hollow sections are common but not always harmless.

What they indicate:

• Old branch failures

• Decay from the inside out

• Long-term fungal rot

If more than 30% of the trunk's diameter is hollow, the tree may be unstable.

3. Peeling or Missing Bark

Healthy bark stays attached. When large sections peel off, it’s a red flag.

Common causes:

• Insect activity

• Sunscald

• Disease

• Root damage

This is often one of the earliest and easiest signs homeowners overlook.

4. Mushrooms Growing on the Trunk

Mushrooms or fungal conks indicate active decay inside the tree.

This means the structural wood is breaking down—which often makes removal necessary for safety.

5. A Leaning Tree Trunk

A slight lean is normal. A new or worsening lean is not.

Danger signs:

• Soil lifting on the opposite side

• Exposed roots

• Lean increasing over weeks or months

This can be a sign the root system is failing.

6. Oozing Sap, Wet Spots, or Dark Stains

This may indicate:

• Bacterial infections

• Insect infestations

• Internal rot

• Stress injury

If there’s a strong odor or foaming, it likely requires immediate care.

7. Multiple Trunks or a Split Trunk

Trees with two or more trunks (called codominant stems) are prone to splitting.

Support options include:

• Cabling

• Bracing

• Strategic pruning

• Removal (if failure is likely)
