Emerald Ash Borer are beginning to make their way east from Michigan, where they have had catastrophic devastation of the Ash Tree population. If you have Ash trees on your property, please be aware that they will be in danger when this pest invades New Jersey.  There have been infestations in the lower Hudson Valley of New York and some in Central Pennsylvania.

Ash Trees

The larvae feed between the bark and wood, creating S-shaped channels that cut off the tree’s ability to draw up water and nutrients. These channels can only be seen if the bark is peeling away. However, when the larvae turn into Emerald Ash Borer, they exit the bark and leave a “D” shaped hole.

Trees that are already infested show signs of canopy decline, and those who have lost 50% or more of the canopy most likely are untreatable. The current prescribed method of treatment is a systemic soil injection that will uptake an insecticide to the effected layer. Those Ash Trees that have not been effected could greatly benefit from Deep Root Fertilization.

Please call to schedule a free consultation with one of our Arborists if you have Ash trees that need an evaluation.
