The Master Gardener program is one of the most recognized and visible Extension programs in the state. Volunteers represent the University y of Minnesota, and citizens depend on them for reliable, research-based information on best practices for home landscapes. More important than an extensive background in horticulture is an active interest in gardening, learning, and sharing knowledge with others.
Nationally, there are nearly 100,000 volunteer Master Gardeners. They reach about 5 million people each year—the equivalent of more than $100 million in value to communities. In Minnesota, the Master Gardener program is coordinated by University of Minnesota Extension and has strong ties to the research and outreach of the Department of Horticultural Science. The activities of more than 2,300 Minnesota Master Gardeners benefit schools, community gardens, youth programs, environmental education programs, farmers markets, and much more.
