Newton residents who want to signal their commitment to chemical-free lawns can grab a pesticide-free yard sign from Green Newton for a $25 donation, but the deadline is Monday, Aug. 17.

The 11-by-16-inch signs are meant to be displayed in front yards, letting neighbors know the property avoids chemical pesticides. Green Newton, the volunteer-run environmental nonprofit founded in 1990, promotes integrated pest management and organic lawn care as part of its broader climate work in the city.

The signs are free with the donation.

Donors can give online at greennewton.networkforgood.com/projects/86756-green-newton and then contact [email protected] to arrange pickup. The contact for the campaign, Marcia Cooper, was named a 2026 Commonwealth Heroine by the Massachusetts Commission on the Status of Women for her contributions to Green Newton and the Newton community.

Green Newton is 99% volunteer-managed and has worked with the city on clean energy, waste reduction and pesticide-reduction programs for more than 35 years. Executive director Judy Jacobs leads the organization alongside president Alan Gordon and board chairman Dan Ruben.

"People can make changes in what they do on a daily basis that will have a measurable impact," Gordon told the Newton Beacon in a May profile of the organization. "There are a lot of small changes that people can make that do make a measurable difference."

The nonprofit's advocacy also helped shape Newton's 2023 Sustainable Food Service Ware, Packaging, and Single Use Ordinance, which Gordon has described as among the most comprehensive plastic-reduction measures of any Massachusetts municipality. Green Newton was selected as a 2026 Newton Rotary Club grant recipient.

Donations must be completed by Monday, Aug. 17. Details are on Green Newton's website.
