WSU Thurston County Extension Master Gardener Volunteer Training Details

Next to digging in the dirt, there’s almost nothing gardeners enjoy more than learning about their favorite plants. One of the easiest ways to increase your gardening knowledge and give back to the community is to enroll in WSU Extension’s Master Gardener volunteer training. For forty six years, Washington State University Extension has been training Master Gardener volunteers in the science and art of gardening.

The WSU Master Gardener course provides WSU research-based information on how to improve soil, identify common plant pest problems including insects and diseases and weed problems, as well as honing your gardening skills. “Hands-on” workshops provide advanced training on pruning, composting, plant propagation and a host of other practical gardening skills.

There is a misperception that to become a WSU Master Gardener you must know everything about gardening. To be a WSU Thurston County Master Gardener you must have gardening experience, but more importantly you must commit to sharing accurate gardening information with our community.

The purpose of the WSU Master Gardener training program is to prepare you to do gardening-related volunteer service in our local communities. Volunteers who are part of the comprehensive core training course will learn the latest information on how to successfully grow their favorite ornamentals, veggies, fruit, and a whole lot more. After completing WSU Master Gardener core training, graduates agree to perform 60 hours of approved volunteer activities before earning the WSU Master Gardener title. Volunteers can choose from a wide array of activities, suited to individual tastes and talents, to satisfy this requirement.

Our 2019 training class is full. We only train once a year from January – June. Applicants accepted into the WSU Master Gardener volunteer training program participate in 21 weeks of classes in person and at home by using the on-line training program. Our in person trainings will happen from 9 a.m. to 4 p.m. on alternating Friday’s.

Applications and training information for the 2020 training course will be posted here after October 1st. For more information or to be placed on the interest list (we’ll email you a reminder when training information becomes available) contact:

Cori Carlton, Program Manager at 360-867-2162 or
