What is MGPW?

Master Gardeners of Prince William (MGPW) is the supportive organization for active Master Gardener Volunteers in Prince William County, Manassas City and Manassas Park. There are approximately 200 active volunteer environmental educators serving in various capacities.  Volunteers attend 75 hours of classroom instruction for training, and then serve in a 50 hour internship over a period of one year before becoming Master Gardener Volunteers (MGV). To remain an active Master Gardener Volunteer, 20 hours of service and 8 hours of approved continuing education are required per year. Volunteers who graduated five years prior are required to return to training to re-take core classes in Water Quality, Integrated Pest Management, Lab skills (2 classes) and Turf.

Volunteers and volunteerism are central to the MGPW mission as we strive to make our community a more sustainable, healthy and beautiful place to live and to educate residents about the many benefits of gardening, including the opportunity to grow nutritious, healthy food, environmentally friendly landscapes, all with the ultimate goal of protecting water quality in local waterways and the Chesapeake Bay.

We accomplish this through the actions described in “Our Programs”
