Applications for the 2023 Master Gardener class are available now! Continue reading for more information.
Applicants should note that MG Trainees are WSU volunteers and are thereby subject to the Governor’s Proclamation 21-14.1 (website) “COVID-19 Vaccination Requirement” as well as any other COVID protocols required by the state, WSU, Snohomish County, and any other applicable local authority. All COVID-19 protocols will be strictly enforced.

Becoming a Master Gardener 

Join over 300 WSU-Snohomish County Extension Master Gardener (MG) volunteers in teaching good gardening and related horticulture and environmental stewardship practices to Snohomish County residents while at the same time learning and and having fun working with other like-minded volunteers.

Training to become a MG focuses on familiarization and learning how to use resources to research, educate, mentor, and answer horticulture questions for the general public in a collaborative environment. With that in mind, all quizzes and exams are open book and can be re-taken. No memorization is required.

MG Training for 2023 is expected to occur in-person, at Willis Tucker Park in Snohomish. Classes will be held on Thursdays, beginning January 12th and ending on April 6th.  We will be following all COVID-19 related public health guidelines that may be in effect at that time, if any. If it is inadvisable to hold classes indoors, at that time, it is anticipated that some or all classes will be held via Zoom.

Tuition for this extensive training program is $375 plus a minimum volunteer commitment of 40 hours during the first year, after which Certified WSU MG status is awarded. Certified Master Gardeners may continue in the MG Program by meeting a minimum annual volunteer commitment of 35 hours.

Successful applicants demonstrate a strong volunteer ethic and a deep sense of commitment, coupled with a willingness to learn and share what they learn.

Master Gardener Class of 2023 applications (pdf) are now available. Check the section to the right for more information. Application deadline is October 30, 2022.
