ALL YEAR-WSU Extension Yakima Master Gardener Program

01/4/2024 - 01/10/2025

Location: 2403 South 18th Street, Suite 100

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

Who We Are…

In Yakima County in 2015 – 117 active and 15 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, Central WA State Fair and Yakama Nation Night out.

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 has been 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.


Master Gardeners are on hand to help you with issues in your home and back yard. Our Plant Clinic is stocked with a large library of resources, modern technology, and motivated, trained, and experienced Master Gardeners.  It helps us help you if you can bring in samples to support your questions… branches of a sick plant, insects that you’ve trapped, photos, etc.
