Emerald ash borer is present in Middle Tennessee, and untreated ash trees are at serious risk. This invasive insect attacks ash trees beneath the bark, disrupting the flow of water and nutrients. By the time canopy decline is obvious, damage may already be advanced. HT Tree provides emerald ash borer treatment guidance in Nashville with a health-first arborist approach for homeowners who want to protect valuable ash trees.
What this service includes
Emerald ash borer larvae feed under the bark, creating galleries that weaken the tree from the inside. Warning signs can include thinning canopy, dead upper branches, bark splitting, woodpecker activity, D-shaped exit holes, sprouts along the trunk, and gradual decline. Because symptoms may appear late, ash trees in affected areas should be evaluated before severe decline is visible.
Warning signs to watch for
- Thinning or dieback in the upper canopy of an ash tree
- D-shaped exit holes or S-shaped galleries under loose bark
- Increased woodpecker activity on the trunk or limbs
- Bark splitting or blonding where bark has been chipped away
- Sprouts emerging from the trunk or base of the tree
- Nearby ash trees declining or being removed
How HT Tree diagnoses and handles it
HT Tree begins by confirming whether the tree is an ash, reviewing its current health, and assessing whether treatment is still reasonable. Healthy or moderately affected ash trees may be candidates for treatment designed to protect the vascular system from further borer damage. Severely declined ash trees may not respond and can become brittle and hazardous, making timely removal safer.
Why acting early matters
Early action is critical with EAB. Treatment is most effective before major canopy loss. Waiting until the tree is mostly dead often leaves fewer options and can make removal more dangerous because dead ash wood becomes brittle. If you have ash trees in Nashville or Davidson County, an arborist evaluation can help determine whether protection, monitoring, or removal is the right path.
What to expect
During an ash tree visit, HT Tree will look for species characteristics, canopy symptoms, bark evidence, site stress, and safety concerns. The recommendation may include treatment timing, ongoing monitoring, or removal if the tree is beyond saving. HT Tree serves Nashville and nearby communities within 20 miles of the office and is available 24/7 when declining ash trees create urgent hazards.

Can an ash tree be saved after EAB appears?+
Sometimes, especially if the tree still has a strong canopy and treatment begins early.
How do I know if I have an ash tree?+
Ash trees have distinct branching and leaf patterns. HT Tree can identify the tree during an evaluation.
Should every ash tree be treated?+
Not always. Health, location, size, value, and existing damage all affect the recommendation.
Are dead ash trees dangerous?+
They can be. Dead ash trees often become brittle, so removal should be handled carefully by experienced professionals.
