Pierce County Master Gardener Volunteer Training
The WSU Extension 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 a range in experience or knowledge about horticulture, but all have a desire to learn. By joining the program, you are committing to serving the community as a volunteer gardening/horticulture educator. Interested in joining the WSU Extension Pierce County Master Gardener Program? Complete the application (information below) and agree to the WSU Master Gardener Program expectations.
Training
All WSU Extension Master Gardeners (EMG’s) 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 (EMG) volunteer include 3 main components:
- Green School online course. The online course will take place over a 20-week period between October 2026, and February 2027. 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.
- Local Volunteer Training. Trainees attend in-person labs or field trips at locations across Pierce County, WA. Applicants should anticipate being available to attend in-person sessions (primarily in Puyallup).
- Internship/volunteer service. Upon completing their training, trainees transition into their internship. As interns, they volunteer alongside certified WSU Extension Master Gardeners, 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 include answering garden questions at our answer clinic, 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 in Pierce County will be for the training that begins in October 2026. The application process will include the following steps:
- Interested applicants can apply using our online application between July 1st – 31st, 2026.
- Accepted applicants will be notified by the end of August.
- In September, after applying for and being accepted into the volunteer program, you will be asked to complete a mandatory background screening.
Ongoing Commitment
WSU Extension Master Gardeners are active 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!

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.
