Protecting Nashville’s Ash Trees: Defending Against the Emerald Ash Borer with Tree Masters of Tennessee

A Local Threat to Nashville’s Trees

In Nashville and its surrounding communities, ash trees are a beloved part of our neighborhoods, shading homes in Green Hills, lining streets in Brentwood, and adding charm to yards in Hendersonville. But these trees face a serious challenge from the Emerald Ash Borer (EAB), a tiny, metallic green beetle that’s been spreading through our region since 2010. First detected in Knox County, the EAB has reached Davidson County and nearby areas, threatening ash trees in our backyards and parks. At Tree Masters of Tennessee, we’re committed to helping our Middle Tennessee neighbors save their trees and keep our communities green. In this post, we’ll guide you through identifying the EAB, spotting infested ash trees, and exploring effective treatment options tailored to the Nashville area’s unique needs.

 

Understanding the Emerald Ash Borer

The Emerald Ash Borer (Agrilus planipennis), an invasive beetle from Asia, arrived in North America via wooden packing materials and was first identified in Michigan in 2002. Since hitting Tennessee, it has caused significant damage, with larvae burrowing under the bark to feed on the tree’s vascular system, blocking water and nutrient flow. This can kill an ash tree in just three years if untreated. In the Nashville area, the EAB targets green, white, black, and blue ash trees, as well as white fringetree, impacting urban spaces like Centennial Park and suburban yards in Belle Meade. The beetle spreads through flight but also travels on firewood—a concern in our region, where camping is a summer staple. Wood movement quarantines help, but early detection and treatment are essential to protecting our trees.

 

Identifying Ash Trees and EAB Infestation in Middle Tennessee

Saving your ash trees starts with knowing how to spot them and recognize EAB damage, especially in the Nashville area’s humid summers and variable weather. Here’s what to look for:

Recognizing Ash Trees

Ash trees are common in Middle Tennessee. Identify them by:

  • Leaves: Compound with 5-9 leaflets, arranged opposite each other, turning vibrant yellow in Middle Tennessee’s fall.
  • Branches: Opposite branching, distinct from other local trees like oaks or maples.
  • Bark: Smooth on young trees, forming deep, diamond-shaped ridges as they age, especially noticeable in older neighborhoods like East Nashville.

Not sure if your tree is an ash? Our team at Tree Masters can visit your property in Nashville or nearby areas like Murfreesboro for a professional identification.

Signs of EAB Infestation

The EAB attacks from the canopy down, making early signs subtle. In Middle Tennessee, where summer heat and storms can stress trees, distinguishing EAB damage is critical. Watch for:

  • Canopy Dieback: Thinning or dying branches at the tree’s top, often mistaken for drought stress in Nashville’s hot summers.
  • Basal Sprouts: New growth at the tree’s base or trunk, signaling the tree’s struggle, common in ashes in flood-prone areas near the Cumberland River.
  • D-shaped Exit Holes: Small (1/8 inch) D-shaped holes in the bark, left by adult beetles emerging in June, visible during Nashville’s warm spring-to-summer shift.
  • Woodpecker Damage: Increased activity from woodpeckers, like the red-bellied ones common in our area, feeding on EAB larvae under the bark.
  • Bark Splitting: Vertical splits revealing larval galleries, often seen in trees stressed by Middle Tennessee’s weather.

If you spot these signs, act quickly—contact Tree Masters of Tennessee for an expert evaluation. Even trees with symptoms can often be saved with prompt treatment.

 

Effective Treatment Options for Nashville’s Ash Trees

Nashville’s ash trees are worth protecting, not only for their beauty but for their role in cooling our homes, boosting property values, and supporting local wildlife. Ignoring EAB or removing infested trees leads to loss, but treatment offers a practical, affordable solution. At Tree Masters, we use a highly effective trunk injection method to combat EAB while prioritizing Middle Tennessee’s environment.

Why Choose Trunk Injection?

Unlike soil drenching or spraying, which can introduce chemicals into Nashville’s waterways or harm pollinators like our native honeybees, trunk injection delivers treatment directly into the tree’s vascular system. This approach is:

  • Fast-Acting: Reaches all parts of the tree quickly, vital in Nashville’s short growing season.
  • Long-Lasting: Provides up to two years of protection, reducing treatment frequency.
  • Environmentally Friendly: Contains the treatment within the tree, safeguarding Middle Tennessee’s streams and wildlife.
  • Proven Effective: Trusted by foresters and arborists nationwide, with a strong history of saving ash trees.

How Trunk Injection Works

The trunk injection process is straightforward and minimally invasive:

  1. Plug Insertion: A small plug is inserted into a drilled hole in the tree’s trunk, creating a secure entry point for the treatment.
  2. Injection: A precise dose of treatment is injected through the plug, rapidly spreading to the trunk, branches, and leaves to target EAB larvae and adults.
  3. Healing: The plug seals the injection site, preventing infection and allowing the tree to heal naturally, well-suited to Nashville’s humid climate that promotes quick recovery.

This method provides up to two years of control, making it more cost-effective than removing and replacing a tree, especially compared to routine expenses like a monthly utility bill.

The Value of Professional Treatment

DIY treatments can be unreliable, particularly in Middle Tennessee’s variable weather conditions. Our certified arborists at Tree Masters ensure accurate application using advanced equipment, followed by regular check-ins to monitor your tree’s health. Whether you’re in Brentwood or Murfreesboro, we deliver tailored care to keep your trees thriving.

 

The Cost of Doing Nothing in Middle Tennessee

Failing to address EAB can have serious consequences for Nashville-area homeowners and communities:

  • Tree Loss: Untreated ash trees typically die within three years, requiring costly removal, especially in urban areas.
  • Property Value: Healthy trees can boost property values by up to 15%, a key factor in Nashville’s competitive housing market. Dead trees hurt curb appeal.
  • Ecosystem Impact: Ash trees provide shade, stabilize soil along Nashville’s creeks, and support local wildlife. Their loss affects local climates and biodiversity.
  • Safety Risks: Dead ash branches become brittle, posing dangers during Middle Tennessee’s frequent thunderstorms.

Treating your trees preserves their beauty, enhances your property, and helps keep Nashville’s neighborhoods vibrant and green.
