Information about the WSU Master Gardener Program volunteer expectations and the application can be found below.
Training
All WSU Extension Master Gardener volunteers receive in-depth horticulture training provided by university faculty, staff, and specialists. Training is critical to ensure that all volunteers have access to the information necessary to support our mission. Training to become an Extension Master Gardener volunteer include 3 main components:
- Green School online course. The online course will take place over a 20-week period between October 5, 2025, and February 21, 2026. Green School offers flexible, remote and hybrid training options. This includes self-paced online classes and online review sessions with subject matter experts from WSU. Courses are specific to the PNW’s climate, soil, environment, insects, wildlife, and plants. Training is a big commitment and includes reading (online, no text required), homework, quizzes, in-class activities, lectures, and a final exam.
- In-person labs/field trips. Trainees attend in-person labs or field trips at locations across Grays Harbor and Pacific Counties, WA. Details about labs/field trips coming soon.
- Internship/volunteer service. Upon completing their training, trainees transition into their internship. As interns, they volunteer alongside certified WSU Extension Master Gardener volunteers, enhancing their knowledge and skills while gaining comfort in community education and program participation. Interns are expected to complete 40 hours of volunteer service their first year. Volunteer service includes answering garden questions at our plant clinics, helping to maintain one of our demonstration gardens, giving presentations, or helping with our children’s education team – to name just a few of the many opportunities.
Application Process
The next application process for Grays Harbor and Pacific Counties will be for the training that begins in October 2025. The application process will include the following steps:
- Interested applicants can apply between July 1st – 30th, 2025.

Ongoing Commitment
WSU Extension Master Gardener volunteers are active in their own counties across the state and their impacts are impressive. We have a user-friendly reporting system so that logging hours, reporting outreach, and signing up for projects is simple. We’re required to report our efforts locally and to the state annually – we want to show off the good work our volunteers are doing! Check out our Annual Reports to read more. 2023 WSU Extension Master Gardener Program Annual Report
After we’ve put our outdoor gardens to bed, we start our annual renewal process for all Master Gardeners. Annual certification in the Extension Master Gardener Program is not automatic. After completion of Green School and your internship commitment, you will become certified. To maintain certification, volunteers must give at least 25 hours of service and earn at least 10 hours of continuing education each year. Volunteers who have met the minimum requirements to remain certified will be offered the opportunity to request continuing certification for the following year.
There is no fee associated with annual certification.
