WHAT YOU NEED TO KNOW
Three Quick Things About
Emerald Ash Borer
Is It an Ash Tree?
Opposite branches, compound leaves with 5–9 leaflets, and diamond-pattern bark are common ash-tree traits. Not sure? We’ll identify it.
Warning Signs
Watch for crown thinning, small D-shaped exit holes, bark splits, new shoots low on the trunk, or increased woodpecker activity. Other problems can look similar, so professional diagnosis matters.
Can the Tree Be Protected?
Healthy ash trees may be candidates for protective treatment. Advanced decline or structural damage may make removal safer. An arborist should assess the tree first.
