All residents of Arlington and Alexandria are eligible to enroll in the Master Gardener Volunteer Training. Trainees receive about 70 hours of hands-on and classroom education from Extension agents and specialists, university faculty, green industry professionals, and Arlington and Alexandria park and recreation administrators. Newly graduated Master Gardener Interns then complete the remainder of their 120 hours of training working on class projects, demonstration gardens, Horticulture Help Desk, plant clinics, and community special events. After completing these additional training/service hours, Interns become Certified Master Gardeners.
Once certified, Master Gardeners are eligible to become members of Master Gardeners of Northern Virginia (MGNV). MGNV, a registered non-profit led by an elected board of officers, is an organization of volunteers who work with the staff of Virginia Cooperative Extension (VCE) to encourage and promote environmentally sound gardening practices.
