Every ash tree in Central New York is in danger from the Emerald Ash Borer– an invasive pest.
In 2013, emerald ash borer was discovered in DeWitt, and Kristina Ferrare, a forestry extension specialist at Cornell Cooperative Extension, says it’s been spreading.
It takes three to seven years for ash trees to die, Ferrare says.
Ferrare says if you have one or two special ash trees in your yard that are infected, it might be worth it to explore the treatment options, but if you have several ash trees like town parks do, that might be too expensive and your best bet might be to cut them down.
Those at the Cornell Cooperative Extension are willing to help those who need to identify problem ash trees in their yard.
