The Ash Trees are Dying

If you have ash trees on your property in Oak Ridge, they are either DEAD or DYING.

Ash trees are easy to spot. Β They are some of the most beautiful large trees in Oak Ridge, but not for long. Β Unless they are treated, there will likely not be a single living ash tree in Oak Ridge in five or so years. Β Not one untreated tree is expected to survive.

Nationwide, ash trees are being destroyed by the Emerald Ash Borer. Β The imported pest are killing all untreated trees in affected areas.

If you own an ash tree, it can sometimes be saved if the tree is not too badly damaged.

Act now – do not wait for signs of distress!

Call 865-425-1803 to discuss dangerous trees.
