Choosing an Arborist for Ash Treatment in Watertown
Every fact cited
Look for ISA certification, proof of insurance, and a provider who can speak specifically to Watertown’s June 2025 EAB confirmation rather than generic regional talking points. Given the city’s own 20-year canopy goal around reducing ash dependency, a good local arborist should be able to help you think past just this one tree — toward whether treatment or eventual replacement makes more sense for your property’s tree mix long term.
Should I ask about replacement species even if I'm treating my ash for now?
It's a reasonable question to raise, especially given Watertown's stated goal of reducing ash to about 10% of canopy citywide — a good arborist can advise on diversifying your yard's trees over time even while treating an existing ash.
