Emerald ash borer treatment works best while an ash tree is still actively moving water and nutrients through its system. As trees start shifting toward dormancy in the coming weeks, that window for effective treatment narrows considerably.
Middle Tennessee has significant ash borer pressure, and treatment is one of the few tree health services where timing genuinely changes the outcome. A tree treated now has a much better chance of absorbing the treatment fully than one treated after growth has slowed for the season.
If you've got an ash tree you've been meaning to have looked at, this is the stretch of the year where it's worth making the call rather than waiting until spring. Not every ash tree needs treatment, but the ones that do benefit most from acting now.
Do you know if you have ash trees on your property? A lot of homeowners in Franklin and Brentwood aren't sure until someone points them out.
