The Rutgers Master Gardeners of Union County Gardening Helpline is a free local resource available to residents. CanvaUnion County residents now have access to free expert gardening advice through a helpline staffed by trained Master Gardener volunteers who can assist with everything from pest identification to soil improvement. The Union County Board of County Commissioners and Rutgers Master Gardeners of Union County operate the service, which residents can access by calling 908-654-9852, emailing mastergardeners@ucnj.org, or visiting the headquarters at 151 Grant St. in Berkeley Heights. Union County also offers a 2026 Master Gardeners training program for residents interested in gardening education and community service. Beyond the helpline, Master Gardener volunteers maintain a 1.5-acre demonstration garden at the Trailside Nature & Science Center in Mountainside.
