Washington State University and University of Idaho Extension Master Gardener Class Information

Washington State University and the University of Idaho Extensions are now accepting applications for the Master Gardener Program.  Topics for the master gardener program include yard, garden, small fruits, tree fruits, landscaping, and much more.

Adults in the Palouse Region interested in becoming a Master Gardener or taking Horticulture classes will have two opportunities starting in January 2022. This is offered through Asotin, Garfield, and Whitman Counties Extension in Washington and Nez Perce County Extension in Idaho.

The second opportunity is offered through Latah County Extension in Idaho.

To become a Master Gardener Volunteer, participants are expected to complete the classroom and module instruction (if applicable) and complete 40 hours of volunteer service in support of the program.  In addition, WSU Extension Master Gardeners will complete a background check and log their volunteer hours.
