Wisconsin Extension Master Gardener Program

The Wisconsin Extension Master Gardener Program, based at the University of Wisconsin-Madison, is a network of dedicated horticultural volunteers committed to advancing gardening knowledge and community service throughout Wisconsin. The program equips Master Gardeners with university research-based horticulture training to address local and statewide gardening needs through education and volunteer activities. By combining continuing education opportunities with community outreach, the program empowers gardening enthusiasts to make a meaningful difference in their neighborhoods while supporting local organizations with expert plant-related guidance and services. Operating under the Wisconsin Idea—the principle that education should extend beyond campus to transform lives and communities—the Master Gardener Program connects people with practical gardening expertise and fosters lifelong learning in horticulture.
