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:
