Master Gardeners of Northern Virginia (MGNV)

EIN: 54-1345818

Mission Statement

To promote horticultural volunteerism and community improvement through trained volunteers, by fostering communication, education, and fellowship among those involved in the Arlington/Alexandria Extension Master Gardeners Program and supporting and promoting the program and its volunteer educational activities.


Program Summary

Through Virginia Cooperative Extension (VCE), Extension Master Gardener volunteers contribute thousands of hours annually to community education programs in Arlington County and the city of Alexandria. We maintain eight demonstration gardens that illustrate the wide variety of plants that grow well in our area as well as overall garden care. We operate plant clinics in farmers’ markets and a public library as well as at special events. We field a wide range of gardening questions through the Extension Master Gardener Help Desk at the Arlington County VCE office. We conduct public workshops in such areas as container gardening, composting, removing invasive plants and insects (such as spotted lanternfly and porcelain berry), and lawn care.  We provide free online classes, including weekly programs with original content focusing on best management gardening practices, sustainable landscaping, and urban agriculture.  We support horticulture therapy and school gardening projects, and we respond to other community needs as they arise.

What ways can the public get involved?

If you want to be a volunteer educator, love gardening, and want to protect our environment by sharing what you learn with our community, consider becoming an Extension Master Gardener (EMG). Once certified, EMGs teach the community about our best management practices for urban agriculture and sustainable landscaping. EMGs retain their certifications by annually completing 20 volunteer hours and 8 hours of continuing education. For more information about training or becoming an EMG, please contact our Volunteer Training Program Coordinator, Leslie Fillmore, by email at LeslieF7@vt.edu.
