Protecting Your Ash Trees Before It’s Too Late

Ash trees are a big part of many Brentwood yards, and when they start to decline, it often happens quietly at first. By the time big branches are dying, the problem has usually been at work inside the tree for a while. A simple question-based ash tree health evaluation in Brentwood can help you notice early warning signs before the damage becomes hard to fix.

The emerald ash borer, along with other insects, disease, and stress, can weaken ash trees in our area. You do not need special tools or training to start checking your trees. You only need your eyes, a little time, and the right questions. Mid to late summer, especially around late July, is a great window to look closely at the canopy, bark, and root area while the tree is fully leafed out. When your answers raise concern, a local tree care professional can confirm what is going on and advise on treatment or removal if needed.

Start with Location and History of Your Ash Tree

Before you look at leaves or bark, think about where your ash tree lives and what it has been through. The spot on your property and its history can tell you a lot about how strong or stressed it is.

Ask yourself: Where is the tree located and how exposed is it? Notice things like:

Full sun all day or part shade
Close to a driveway, sidewalk, or street
Near past construction work or heavy equipment
Areas with hard, compacted soil from parking or constant foot traffic

These stress factors can make it harder for the tree to take in water and nutrients. A stressed ash tree is more likely to be hit hard by emerald ash borer and other pests.

Next, ask: What is the age and maintenance history of the tree? Think about:

Has it ever been properly pruned?
Has it been topped or cut back harshly in the past?
Has it had storm damage or broken limbs?
Has a driveway, patio, or utility trench cut into the root area?

Older ash trees, or ones that have been damaged again and again, tend to decline faster. These should be checked more often.

Finally, ask: Has anything changed recently around the tree?

New irrigation or sprinkler systems
New landscape beds over the roots
Fresh turf or sod laid over the root zone
Changed drainage that leaves the area soggy or extra dry

Sudden changes in moisture or soil grade can cause leaf drop, thinning, and yellowing that can look like insect or disease problems. Knowing about these changes helps a professional sort out what is really going on.

Canopy and Leaf Questions You Should Ask First

Now look up. The canopy gives some of the clearest clues about ash tree health.

Ask: Does the canopy look thin, patchy, or late to leaf out this summer? Compare:

This year’s leaf coverage to what you remember from previous summers
Your ash tree to other ash trees nearby that look full and green

Warning signs include:

Dieback starting from the top of the tree
Bare tips at the ends of branches
Smaller than normal leaves
Yellowing or thinning on one side of the tree only

Then ask: Are there dead branches or clusters of brown leaves that never dropped? This can mean:

Chronic decline if you see dead twigs and limbs scattered all through the canopy
More recent storm damage if deadwood is mostly in one area or from broken branches

Large dead limbs hanging over homes, driveways, or play areas are a safety risk, especially during summer storms. They should be inspected quickly.

It helps to take photos from the same spot once a week for a few weeks. That way, a tree care expert can see if the canopy is getting worse, holding steady, or showing new bare areas.

Trunk, Bark, and Root Zone Checks Homeowners Can Do

Next, walk around the trunk and look from the ground up. You do not have to peel bark or climb the tree. Just observe and take notes or pictures.

Ask: Do you see bark splitting, peeling, or unusual cracks?

Long vertical cracks in the trunk
Bark that is lifting away or loose in patches
Flaking bark that exposes lighter wood underneath

These can be signs of internal decay, past injury, or insect damage. Also watch for heavy woodpecker activity or patches where birds have stripped the bark as they hunt for insects hiding underneath.

Then ask: Are there small D-shaped exit holes, galleries, or oozing sap? With emerald ash borer, people often see:

Tiny D-shaped holes in the bark
Serpentine, winding tunnels just under the bark when it falls off on its own
Rough, split bark where the tree has tried to grow over damage

Other concerns include fungus conks, ant activity going into the trunk, or sunken cankers. These all point to weakened wood and possible structural problems.

Finally, ask: What does the root zone look like at the base?

Exposed, damaged roots
Soil that is heaving or lifting on one side
Mushrooms or fungal growth near the trunk
Constantly soggy or standing water

A healthy root area should have a light layer of mulch 2 to 3 inches deep, pulled back from the trunk so it does not touch the bark. This helps keep moisture even and lowers pest and disease stress.

Seasonal Pest and Disease Questions for Brentwood Ash Trees

Summer is a busy time for insects and diseases in Middle Tennessee, so paying attention now makes a difference.

Ask: Have you noticed unusual insects, sawdust, or leaf damage this summer?

Light chewing on a few leaves is often normal
Heavy skeletonizing, where only the leaf veins remain, is more serious
Sawdust-like material on the bark or at the base can signal boring insects

If you see insects you do not recognize, take clear, close photos of the bugs and the damage. This helps a local tree care specialist decide if you are dealing with a minor pest or something more serious.

Next, ask: Are there spots, blotches, or curling on leaves?

Small spots that show up briefly and then fade can be mostly cosmetic
Large blotches, curling, or leaves dropping early year after year can point to disease problems

When the same disease symptoms repeat every season, it may be time to consider preventive treatments or selective pruning to open up the canopy for better airflow.

Mid to late summer in Brentwood is a good time to:

Confirm possible emerald ash borer symptoms
Notice drought stress before leaves start to color and drop
Plan treatments, pruning, or removal before fall weather arrives

An ash tree health evaluation in Brentwood by a professional can pull together what you see on the outside with soil conditions and trunk checks for a clearer diagnosis.

When Your Answers Mean It’s Time to Call a Professional

After you walk through these questions, some answers should signal that it is time for expert help. Take special note if you see:

Thin, patchy canopy or top-down dieback
D-shaped exit holes or heavy bark splitting and peeling
Large dead limbs over homes, driveways, or play areas
Mushrooms or soft, rotted wood at the base of the tree

These signs point to risk, either from pests like emerald ash borer or from structural weakness that can lead to falling branches or full tree failure.
