Have a gardening question?

Unsure what that insect eating your plants is? Want to know how can you improve your soil? To help you with your gardening questions, the Master Gardeners are ready and willing to research and answer your questions.  We are getting back to staffing our normal Monday office plant clinic from 1-3pm. As this is still a transition due to being closed to in person clinic during COVID-19, we may not be fully staffed yet. Call ahead to ask if a Master Gardener is in, otherwise you can email your plant questions to:, use the Clinic Question section on the Extension website, or call and leave a message at 360-427-9670 Ext. 687. We would love to help you!

Our clinic runs mid-January to mid-November. If you have a question, please continue to send it in via email, and we can assist as soon as we can.

We also will be back to staffing a plant clinic table at the Shelton Farmer’s Market on Saturdays for the 2022 market season! Stop on by!

MG Training Information: Interested in Becoming a Mason County Master Gardener?

With Covid-19 Restrictions it is uncertain when we will begin our next Master Gardener Volunteer Training Program. If you are interested in becoming a Master Gardener Volunteer please submit an application and as the class is scheduled you will be contacted.

WSU Master Gardener volunteers provide educational programs, free advice and answers to questions on home gardening and landscape maintenance, pest management, and composting to Mason County residents.  Volunteers help at plant clinics, classes, our Catalyst Food Bank and Community Demonstration Garden, garden tours, and our annual plant sale.  To become a certified Master Gardener, participants complete the online and face-to-face training programs and fulfill 60 hours of approved volunteer hours within a year of completing the coursework.  After certification, ongoing volunteer hours are required to maintain status as a Master Gardener.  Being a Master Gardener is an opportunity to improve your own knowledge and support the community!  Mason County Master Gardener Training information
