What is a Master Gardener Volunteer?

A Master Gardener is a trained volunteer certified by a university extension program to provide research-based horticultural education to the public. A volunteer completes extensive training in topics such as soil health, plant diseases, and pest management. After completing the training, a volunteer begins to serve. Volunteers educate youth and adults, manage demonstration gardens, and answer gardening questions.

Perhaps you aren’t ready to volunteer yet but want to learn more about gardening? Like the SDSU Extension Master Gardeners Facebook page to stay up-to-date on webinars and workshops open to the public.

"I love working as a volunteer with SDSU Extension as a South Dakota Master Gardener. My mind is stimulated with the up-to-date horticulture information provided which fuels my teaching portfolio, which in turn connects me to my community."

— Sue W. White, Northern Hills Master Gardener
