Become a Master Gardener

Do you want to learn more about gardening, meet new people, and make a difference in the community? The WSU Extension Grant-Adams Master Gardener Program may be just right for you. Learn about science-based knowledge to tackle the yard and garden problems that matter to you, your friends, neighbors, and your community.

Master Gardener training is held every other year in Grant County. Applications and a descriptive leaflet explaining the program can be obtained from the Grant County Extension Office in Moses Lake, through other Master Gardeners, from the website, and at plant clinics or other venues.

Over the past 50+ years, Washington State University Extension has provided guidance and instruction to the gardening public along with training to those who have been certified as Master Gardeners.  WSU has developed new options for anyone who wants to learn gardening principles through the Master Gardener program or for anyone who wants to take gardening classes. Examples are people who want to learn more about gardening in Washington but may not want to serve as Master Gardener volunteers. There may be gardening professionals who are seeking endorsements for their resumes, but are not obligated to volunteer annually, which is a requirement for all Master Gardeners.   

The new program is called Washington Green School, and it offers lots of options to explore.  The attached website links (see box to right) explain the program, options, schedules, and fees, and are quite comprehensive. Sign-ups for any of these classes will take place from July 1 to September 30 of every year. And, if a student is interested in training for the Grant-Adams Master Gardener program, being accepted into the program and finishing the online coursework is an integral part of that training. However, since classroom training/labs are offered every other year in Grant-Adams Counties, those who finish the green school training are eligible to participate in the next round of Master Gardener training, which will begin in August 2026.  Individuals interested in the Master Gardener training can pick up a leaflet available at the Grant County Extension Office at 1525 E. Wheeler Road, Moses Lake. The leaflet explains the Master Gardener biannual training program and provides registration details. Applications can be picked up at the office or requested by emailing ga.mgvolunteers@wsu.edu.

Green School Agreement

The passion demonstrated by WSU Extension Master Gardeners underscores the positive impact that programs like these can have on individuals and communities. The reasons they’ve provided for their involvement highlight the multi-faceted benefits of participating in such a program.

Master Gardeners are unique in their commitment to educating and learning. There is often camaraderie between individuals and opportunities to learn from each other and provide service to the communities we live and work in. And, the program offers individuals a sense of purpose.

If you are passionate about gardening and want to make a positive impact, participating in the WSU Extension Master Gardener program can be a fulfilling and educational experience. It is an excellent opportunity to deepen your knowledge, connect with fellow gardening enthusiasts, and give back by sharing expertise with others.

Trainee-Intern Status

During the fall of the first year, trainees take an online course and attend mandatory classes. Both engaging and interactive lectures, field trips, and hands-on training are provided. Upon completing this phase of the training, the following year, trainees become interns and volunteer a minimum of 40 hours of outreach in approved activities, with help from an assigned mentor. Once that is accomplished, interns become official Master Gardeners.

The Commitment

Master Gardener candidates should have a strong volunteer ethic, commit to becoming a volunteer educator for WSU Extension, abide by WSU Master Gardener regulations, policies, and procedures, and be willing to take additional required training annually and participate in volunteer activities.

Certified Master Gardeners

To maintain the certification, annually, Grant-Adams Master Gardeners take at least 10 hours of educational credit hours, volunteer at least 25 hours in approved outreach activities, and agree to follow pesticide management requirements.

Application Process

Applicants can read about the program from a leaflet or information provided at meetings or plant clinics.

Applications are accepted until August 1, 2026.  They are reviewed, and letters of acceptance are sent to approved registrants. Classes usually commence in late August. Part of the review process consists of a background check required of all Master Gardeners every 3 years and a video on working with children.
