Know.
WCMGA volunteers are trained in the art and science of gardening through the Master Gardener Program of the OSU Extension. We offer home gardeners in Washington County gardening know-how that is reliable, relevant and accessible.
Show.
WCMGA volunteers host gardening presentations, classes and workshops, answer gardening questions by phone, email, and in-person at county events, provide speakers on gardening topics, and maintain two inspiring demonstration gardens where Washington County gardeners can experience the gardens while learning about the plants.


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.
