Research-based gardening information for today’s challenges

Extension Master Gardeners are volunteer community educators cultivating plants, people, and communities since 1973 – and into the future.

Extension Master Gardeners are university trained, volunteer community educators cultivating plants, people, and communities since 1973 – and into the future.

Our changing climate requires that Extension Master Gardeners stay abreast of cutting-edge, research-based gardening practices so we can give unbiased, valuable advice in our communities. The Master Gardener Foundation of Washington State sponsors the advanced education conference.  The Yakima County Extension Master Gardeners offer classes on a variety of topics. Most classes are free, and often involve hands-on activities in our gardens.
