Master Gardener Volunteers – Greene County
The Ohio State University Extension Master Gardener Volunteer Program provides intensive training in horticulture to interested Ohio residents who then volunteer their time assisting with educational programs and activities through their local OSU Extension office. Volunteers don’t need gardening expertise to begin—just a passion for learning and a desire to share that knowledge with others!
What Is OSU Extension?
The Ohio State University Extension is the outreach arm of OSU’s College of Food, Agricultural, and Environmental Sciences (CFAES). Extension professionals translate university research into practical information that Ohioans can use to improve their lives, communities, and environment.
What Is the Agriculture & Natural Resources (ANR) Program?
The ANR program supports farmers, gardeners, conservationists, and landowners through evidence-based education and resources. In Greene County, our ANR team helps address soil health, water quality, urban agriculture, land use, native plant preservation, and sustainable practices.
What Is a Master Gardener Volunteer (MGV)?
Master Gardener Volunteers are trained OSU Extension volunteers who serve as community educators. After completing classroom instruction, MGVs contribute a minimum of 50 hours of volunteer service annually. MGVs support Greene County by providing research-based, unbiased gardening information to homeowners, schools, nonprofits, and local governments.
Who Are the Greene County MGVs?
Greene County’s MGVs come from all walks of life but share a commitment to sustainable gardening, environmental stewardship, and lifelong learning. Together, they lead plant clinics, speak at community events, maintain demonstration gardens, and host workshops and public programs.
