The University of Wisconsin-Madison Extension Master Gardener Program supports a network of individuals, known as Master Gardeners, dedicated to horticulture education, service, and lifelong learning. Through University research-based horticulture training, Master Gardeners are equipped to address needs and opportunities in their community and throughout the state.

Training is required to become a Master Gardener. Individuals wanting to become a Wisconsin Master Gardener should participate in a learning opportunity from the Wisconsin Extension Horticulture Program such as a county-based, in-person course (limited availability) or sign up for the statewide online course, Growing and Caring for Plants in Wisconsin: Foundations in Gardening (formerly called Foundations in Horticulture- Growing and Caring for Plants in Wisconsin) and complete the online Master Gardener Onboarding course.  

Growing and Caring for Plants in Wisconsin: Foundations in Gardening
This course teaches participants university research-based methods to successfully grow plants and manage common pests. This course introduces a decision-making framework that focuses on understanding how plants grow, why pests and problems happen, and how to keep plant problems from happening. It emphasizes using brain power, common sense, and elbow grease rather than the spray bottle on plants grown inside and out.

To give participants the best information on improving their gardening skills, this twelve-part virtual course includes online videos, readings, interactive quizzes, and scheduled live Q&A webinars with UW Madison horticulture experts. This course, offered annually, is designed to be self-paced so participants can fit it into their schedules. The Wisconsin Extension Master Gardener Program supports Growing and Caring for Plants in Wisconsin: Foundations in Gardening as the primary source of horticultural knowledge required for the Master Gardener program.
