If You Want to Save Your Ash Trees, Now is the Time to Act

Emerald ash borer is here. Infestation has been verified 20 miles away. It is a killer; now is the time to vaccinate any ash trees you want to save, because by the time you find the pretty green insect on your tree, or notice the damage, it will be too late. Infested trees die from the top of the crown down; by the time you can see from the ground that you have damage, the tree will be too far gone to save.

How do I know if I have ash trees?
