In cooperation with the OSU Extension Service, 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. The Washington County Master Gardener Association (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.
