Master Gardeners are trained volunteers who aid University of Wisconsin Extension staff by helping people in the community better understand horticulture and their environment. This site can help you learn about becoming a Master Gardener in Wisconsin, find information about horticultural topics, and connect to the statewide network of Master Gardener associations.
The mission of the Wisconsin Master Gardeners Association (WIMGA) is to support and provide leadership to individuals and local organizations in their mission to assist University of Wisconsin Extension (UWEX) in community horticultural programs through volunteerism, education, and environmental stewardship.
