The Master Gardener Program is a volunteer program for people with a passion for plants, a drive to learn, and a commitment to serve. Candidates for the program may have very little experience or knowledge about horticulture or they may have a lot, but all have a desire to learn.

After completing training, trainees become interns and are required to complete 40 hours of service each year, for two years (80 hours total), to the community by assisting the public in solving their home gardening problems and answering questions. Upon completion of these hours, they become Certified WSU Master Gardeners.

About The Training

Time commitment

The process to becoming a Master Gardener starts with intensive 11-week classroom and hands-on training. Participants are asked to apply only if they can attend 90% of class days. The training is academically oriented and requires approximately 3 – 6 hours per week of outside of the classroom lectures and homework. The course has online components which include chapter readings and quizzes, and a final exam. Active class participation is expected.

Trainees receive over 60 hours of college-level, WSU-certified training. Lectures and labs are taught by university faculty/staff, local and state experts, and Master Gardeners.  The online portion of the training course is divided into modules that cover the core competencies for WSU Master Gardener volunteers in the state.   Computer web access is necessary for compatibility.  In the classroom, we supplement the online content with additional lectures on horticultural topics from local experts, field trips to outstanding local and regional garden and farms, and hands-on learning activities with experienced Master Gardener volunteers.
