Master Gardener Program

Newport News Extension Master Gardeners help the public at an educational information desk.

Extension Master Gardeners are trained volunteer educators. They work within their local communities to encourage and promote environmentally sound horticulture practices through sustainable landscape management education and training. As an educational outreach component of Virginia Cooperative Extension, the Master Gardener program brings the resources of Virginia’s land-grant universities – Virginia Tech and Virginia State University – to the people of the commonwealth. All volunteers are trained and have at least 50 hours of horticultural classes and return at least 50 hours of volunteer community service through their local Extension office.

Since 1979, Virginia Extension Master Gardeners have served communities throughout the Commonwealth by providing unbiased and research-based horticultural information to home gardeners.

Master Gardeners provide a resource for all Extension program areas and for professionals from many other agencies. They provide communities with locally identified programs, including answers to individual questions via hotlines and plant clinics; radio, newspaper, and computer links; educational programs to meet targeted needs; education for the preservation of historic landscapes; urban tree planting programs; and guidance in making the natural environment accessible to all residents regardless of disabilities, incomes, or where they live.

Mission: Sharing knowledge. Empowering Communities.

Vision: To be the Virginia Cooperative Extension volunteer organization extending horticulture and environmental outreach across the Commonwealth.

Core Values:

  • Respect - The environment, each other, and those we serve.
  • Accountability - Wise stewardship of resources. To our organization, our community, and each other.
  • Collaboration - Willing to work with a diverse group to reach a common goal. Actively seeking out partners.

Virginia Extension Master Gardeners are volunteer educators. 

Extension Master Gardeners do not provide free gardening labor--they work to provide research-based horticultural information to Virginia home gardeners.

Virginia Cooperative Extension Master Gardeners contribute to their communities through volunteer service, for example, by holding educational events, staffing help desks, or working to build community gardens.

Master Gardeners bring the research and resources of Virginia’s Land Grants to the people of the Commonwealth.

Even after completing their initial training, Virginia EMGs also have many opportunities for continuing their education. Advanced certifications related to water resources, trees, and land stewardship are offered. The EMG State Office also organizes educational monthly webinars, a quarterly newsletter, and an annual Master Gardener College conference.
