Who are the WSU Master Gardener Volunteers?

We are a volunteer service gardening organization – cultivating plants, people, and communities since 1973.

Our Thurston County program is part of the statewide WSU Extension Master Gardener Program which combines horticulture training and public service. WSU Master Gardener volunteers are trained and certified as community educators to provide professional, unbiased, researched-based home gardening and horticulture information to the public through the following avenues:

WSU Master Gardener Program Priorities – The WSU Master Gardener Program addresses important sociologic and environmental issues by teaching research-based horticulture information. We want people to have important skills and abilities that help mitigate challenges and to understand that everyone has a role to play in creating and sustaining healthy and resilient communities.
