In collaboration with and in support of the OSU Extension Service Master Gardener Program, the Washington County Master Gardener Association (WCMGA) provides relevant, research-based education and outreach to the public about horticulture and household pests. This information promotes sustainable practices that minimize risks to human health and the environment. WCMGA sponsors a wide variety of gardening–related demonstrations, lectures, seminars and workshops in various Washington County Oregon locations. Most of our events are free and open to the public. The WCMGA is a 501c3 non-profit supported by hundreds of volunteers, who work to educate the public about sustainable, affordable gardening.
