What are the most common signs of a dying tree?

The two biggest signs I always see are major dead branches in the upper canopy during summer, and fungal growths like shelf-like mushrooms on the trunk. Both indicate a serious, long-term problem.

Can a leaning tree be saved, or does it need to be removed?

It really depends. If it's a slow, long-term lean, it might be stable. But if the tree started leaning suddenly, especially after a storm, it's an emergency. That suggests root failure, and it's extremely dangerous. An arborist needs to assess it immediately.

How often should I have my trees inspected by an arborist?

For any large, mature trees near your house or high-traffic areas, I recommend a professional inspection every 3-5 years, and always after a major weather event like an ice storm or hurricane-force winds. A consultation is cheap compared to the alternative.

Can I check for a sick tree myself?

You can absolutely do a visual inspection yourself. Walk around, look for the big warning signs: dead branches, deep cracks, fungus, sudden leaning. But when it comes to diagnosing the specific disease or deciding if it's structurally sound, that's where you need a certified pro. Never try to climb or cut on a tree you suspect is unhealthy.

Common Symptoms

Dead or decaying branches, especially 'widowmakers' in the upper canopy.

Cracks or splits in the trunk or major limbs, particularly tight 'V' formations.

A new or sudden lean in the tree's posture, often with heaving soil.

Evidence of pest infestation like holes, sawdust-like frass, or insect galleries.

Fungal growth, such as shelf-like mushrooms or 'conks,' on the trunk or base.

Discolored, wilting, or sparse foliage during the growing season.

Trunk cavities, hollow sounds when tapped, or significant peeling bark.

Changes in ground level around the base, or large roots cracking foundations.

Possible Causes

Pests and diseases, such as Emerald Ash Borer or Dutch Elm Disease, which weaken the tree and allow secondary infections.

Environmental stress from drought, flooding, soil compaction from construction, or extreme temperatures that damage the root system.

Poor pruning practices, especially 'topping,' which creates weak, unstable growth and entry points for decay.

Structural defects that develop over time, like co-dominant stems with included bark that are prone to splitting.

Mechanical damage from lawnmowers, cars, or construction equipment that wounds the bark and vascular system.

Root damage from excavation, trenching, or soil grade changes that sever the tree's lifeline.

Step-by-Step Diagnosis

Step 1

Observe the tree from a distance to assess its overall lean, shape, and foliage density.

Step 2

Inspect the trunk up close for deep cracks, cavities, peeling bark, and fungal growths.

Step 3

Tap the trunk with a rubber mallet, listening for hollow sounds that indicate internal decay.

Step 4

Examine the branches and leaves for deadwood, discoloration, wilting, or signs of insect damage.

Step 5

Check the base of the tree and root flare for decay, mushrooms, girdling roots, or heaving soil.

Step 6

Look carefully on the ground and in bark crevices for sawdust-like frass, a clear sign of boring insects.

When to Call a Professional Tree Service

When you see large, dead, or broken branches hanging in the tree.
If the tree develops a sudden lean, especially after a storm.
You discover large, deep cracks or hollow spots in the trunk or major limbs.
There are shelf-like fungi (conks) or mushrooms growing on the trunk, a sign of internal rot.
The tree is near power lines, your house, or a neighbor's property, and you suspect it's unstable.
The foliage dies back suddenly or the tree defoliates completely out of season.
The job requires a chainsaw and a ladder - a combination that should never be used.

Prevention Tips

Water trees deeply but infrequently during dry periods to encourage deep root growth.
Apply a 2-3 inch layer of mulch around the tree, but keep it from touching the trunk to prevent rot.
Protect the trunk from damage by lawnmowers and string trimmers.
Have young trees pruned by a professional to establish a strong, stable structure for the future.
Avoid compacting the soil over the root zone with vehicles or heavy equipment.
Schedule a professional check-up every 3-5 years for mature trees near your home.
