Ash Tree Identification
As the Emerald Ash Borer (EAB) continues to spread throughout the region, it’s critical to know whether or not those beautiful trees in your yard are ash trees.
If they are, you may want to consider a preventive treatment to help save them from EAB infestation and eventual death.
At this point, doing nothing is not an option. All ash trees in New Jersey, as well as eastern Pennsylvania, will eventually be attacked and killed by EAB – unless they’ve been treated to ward off the beetles.

How To Tell If You Have Ash Trees On Your Property
- Ash trees have opposite branches and buds, not staggered or alternate. Look for leaves and twigs that are attached to the stem or branch directly across from each other.
- The leaves are compound, made up of 5-11 leaflets. Instead of a single leaf attached to a branch, look for a stem that has 5 to 11 leaves arranged opposite each other (see the picture).
- While the bark on younger trees tends to be smooth and gray, mature trees have more of a diamond pattern of ridges and furrows.
