Become a Master Gardener

WSU Yakima County Master Gardeners learn and share our expertise with our community. Master Gardeners welcome YOU!

Who We Are…

In Yakima County in 2019 – 118 active and 24 emeritus Master Gardeners were able to pursue many activities to fulfill our mission of education our communities regarding WSU approved horticultural practices. Our clinic venues answered questions and helped solve gardening problems for home gardeners at our WSU Extension clinic, Farmer’s Market and Central WA State Fair.

Our Demonstration garden at Ahtanum Youth Park and our Heirloom garden are both teaching gardens where classes are held during the spring, summer and fall. We also hold courses four Wednesdays evening in March for the public, our speakers bureau team spoke to several groups throughout the year and our writers guild research and submit gardening articles for both the Sunday Yakima Herald and monthly Yakima Magazine.

Our Youth programs, both in schools and at community events, reached hundreds of youngsters with garden related learning activities.

A recent addition, the Kamaikin Garden on the Yakama Reservation, joins our Community Garden in Buena to help this low-income area grow nutritious, health food.

Our Greenhouse allows us to propagate plants from seed or cuttings to be sold at our annual plant sale to the public in order to raise income to support our Yakima MG program.

The following statistics for hours donated to each venue in Yakima County include:
