Metro Tree Advisory Committee Urges Residents to Address Emerald Ash Borer

4/4/2019

This spring is the time to start your EAB management plan.

Nashville has many beautiful native ash trees in parks, on school grounds, along city streets and in private yards. Sadly, none of these ash trees are immune to the effects of the Emerald Ash Borer, an invasive pest rapidly spreading across Middle Tennessee. Now is the time for Nashville residents to make a decision on how to manage their ash trees.

Managing the effects of the Emerald Ash Borer epidemic includes three options: Treat your tree, let it die or remove it. Early spring is the time to select what is right for your tree. The longer a management plan is delayed, the more it will cost.

Treat it

Sustained insecticide control requires soil or bark treatments every year, or injection treatments every two years for the remaining healthy life of the tree. This option is best for healthy large significant or historic trees. Treatments may be applied by the homeowner or a licensed professional. It’s crucial to treat your tree before it is infested. Insecticides are most effective before infestation symptoms are discovered. Once there is more than 20% dieback of the tree’s crown, treatment may not be effective as the EAB larvae may have damaged the tree too much. If this is your management option, treatment must start now, spring of 2019, as the trees are coming out of winter dormancy and will actively take up chemical treatments.

Let it die

If the tree is in the woods or on open area where its fall would not block access or cause physical or property damage, you can let it die naturally in place and decompose.

Remove it

You can be proactive and have your tree cut down before it becomes infested and dies. If it is not accessible by a bucket truck, then it needs to be cut down before it becomes too brittle for tree workers to climb. Infested ash trees present a serious safety concern.
