What is a Master Gardener?

Master Gardener students examining a leaf specimenMaster Gardeners are community educators trained to work in partnership with WSU Extension to teach the public and enhance the quality of life in the community by promoting sound gardening practices with research-based information.

The 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 or may not have experience or knowledge about horticulture, but all have a desire to learn. By signing up to join the program, you are committing to serving the community as a gardening/horticulture educator. Trainees develop the skills and knowledge to become effective community educators on plants, plant communities, pests and much more.

Trainees receive over 60 hours of college-level, WSU-certified training. Lectures and labs are taught by university faculty/staff, local and state experts, and Master Gardeners. After trainees pass the final exam, they complete 60 hours of volunteer time as intern-trainees, assisting the public in solving their home gardening problems and answering questions. Upon completion of these hours, they become Certified WSU Master Gardeners and maintain certification with continuing education and annual volunteering of a lesser number of volunteer hours.

Topics include:

    • Botany
    • Insects
    • Soils
    • Pesticide Safety
    • Garden Management
    • Landscape Ornamentals
    • Weed Control
    • Pruning
    • Plant Pathology
    • Sustainable Practices
    • Vegetable and Fruit Crops
    • and more!

Tuition for the Master Gardener training is $375. Study materials are included. Volunteer trainees must also complete a national background check through Sterling Volunteers at a cost to the applicant of $14.

Limited scholarships available based on need. Contact Beth ( for more information.


Classes will be held in-person at Whatcom County Public Works – Garden Room (322 N. Commercial St., Bellingham, WA). Field trip and outdoor sessions will be announced.
