article-1339563-0C85C12F000005DC-950_468x332Mission: The purpose of the WSU Extension Master Gardener Program is to train volunteers to be effective community educators in gardening and environmental stewardship. Master Gardeners provide information generated from research at WSU and other university systems.

Who are Master Gardeners?
Master Gardeners are volunteer community educators that are specialists in cultivating plants, people, and communities since 1973. These volunteers are avid gardeners who undergo our intensive training program to become experts about gardening in Jefferson County.

They help gardeners find current safe solutions to local gardening problems; make their communities more environmentally and economically viable by teaching people to protect natural resources; and support community food systems through education and garden support.  Master Gardeners have access to the experts and research resources at Washington State University.
