Master Gardener Program

Master Gardeners are trained volunteers who aid University of Wisconsin-Extension staff by helping people in the community better understand horticulture and their environment.

Anyone can become a Wisconsin Master Gardener, regardless of previous gardening experience or education.  Participants in the program begin by attending the General Master Gardener training, consisting of 36 hours of classroom education on a variety of topics, including basic botany, soil science, plant pathology, entomology, fruits, vegetables, trees, annual and perennial flowers, native plants, wildlife, composting, and more.  After completing the classroom instruction, and passing the final exam, these “master gardener interns” must then contribute 24 hours of volunteer service, doing something related to horticulture, to their communities.  Upon completion of the volunteer service, participants are officially certified as Wisconsin Master Gardener Volunteers.  To maintain certification each year thereafter, 24 hours of volunteer service and 10 hours of continuing education are required.

In Pierce and St. Croix Counties, the Master Gardener program is taught and administered by Diana Alfuth, Horticulture Educator.  The general training is typically offered each fall, beginning just after Labor Day.
