Volunteers are needed to help with a summer garden club, a program for children ages 5-12, at the Columbus School on Hicks Avenue. Middle and high school students are encouraged to volunteer, along with local residents. The garden club will meet on four Wednesdays, July 25 to Aug. 18. The program is free, but registration is required. Contact Susan Schmidt, a parent volunteer, at 781-396-8029 or email@example.com.
