MG Training Information:

Format of the training:

The training includes virtual and in person classroom trainings in addition to online studies. The online study portion includes topic-based modules and open-book quizzes for each module through our Canvas Learning Platform. There is also an open-book final exam at the end of the training. You’ll need reliable computer access and be willing to learn new computer platforms.

What will I learn?

The training focuses on sustainable gardening practices through topics such as pest and soil management and water wise gardening techniques. It covers a wide range of gardening topics that include ornamental, vegetable and native plant gardening as well as community education and public speaking skills.

How many hours a week will I spend in the training?

The classroom sessions are 35 hours a week and require readings and assignments from home before each class. The online study equates to about 2-4 hours of study time a week for approximately 4 months.

What happens after the online course and training?

Once training is completed and you have passed your final exam you will need to complete 40-hours of volunteer time, which includes working at our demonstration gardens, staffing diagnostic clinics, an intern project, and working in the community. These hours need to be completed by the end of the calendar year. You’re required to access our electronic volunteer portal and log your hours.

In total, our Master Gardener Training Program amounts to approximately 150 hours of training and volunteering combined.

Once Master Gardeners complete their first year, they are required to contribute 25 hours of volunteer service and obtain 10 hours of continuing education annually to retain their certification. Every year our Master Gardeners submit 35 hours total and then re-apply for their certification electronically. As Master Gardeners you are allotted 1 year of leave if you should need it and you’re welcome to rejoin the community without retraining. If you should not retain your certification from year to year you are expected re-enroll in the training. It is important to us to support our educators with updated scientific information and community outreach soft skills trainings. Master Gardeners are a go-to community resource and we are proud of that.

What is the cost of the class?

The classroom portion of the training is $195 for those wishing to become a Master Gardener Volunteer or $500 for those who do not wish to become a Master Gardener Volunteer but instead only want to attend the class to receive a certificate of completion.

The online platform portion of the training is $75.

The mandatory national background check for those wishing to become a Master Gardener Volunteer is $14. Once admitted into the program, a background check will need to be completed every 3 years. WSU Master Gardeners are also required to show proof of COVID-19 Vaccination.

The Master Gardener manual can be downloaded for free, or you can purchase a physical manual for $125.

Is there financial assistance available?

Are you a WSU Master Gardener from another county in our state?

Certified WSU Master Gardener volunteers who change residence from another county to Pierce County are asked to obtain a letter of reference from the WSU Master Gardener Program coordinator in the previous county. This letter can be sent to the Pierce County Program Coordinator at

  • The volunteer and program coordinator contact information
  • Testimonials of their commitment to the Master Gardener Program within that county
  • The year of they obtained their certification
  • The total volunteer hours of most recent year

Once the letter is received and accepted by the Pierce County Program Coordinator, the Volunteer will be transferred to the Pierce County Give Pulse data base, receive an PCMG badge and will be paired with a Certified Pierce County Master Gardener to onboard them to the program. This person will mentor the new volunteer for the first year in the county and serve as a resource and support person.

Onboarding will include the following:
• Watch an orientation video to understand local program policies, activities, commitments, etc.
• Watch training videos on Give Pulse, and classes on the differences in climate and conditions between Pierce County and the previous place of residence.
