The Master Gardener course is a volunteer training program, not a general gardening class. It is designed for individuals who wish to become certified volunteers with Missoula County Extension and serve as an educational resource in our community. Master Gardeners act as an extension of Extension’s horticulture programs by sharing research-based gardening information with the public.
