Who We Are

Ozaukee Master Gardeners



  • To serve the needs of gardeners in Ozaukee County by providing university research-based horticultural information and educational opportunities, designed to supplement programs of the University of Wisconsin-Extension (UWEX).

  • To promote understanding of responsible gardening practices and provide a link between the community and UWEX.

  • To develop and increase horticultural knowledge for all Master Gardeners, thereby providing effective horticultural resources and expertise for Ozaukee County residents.

Ozaukee Master Gardeners

  • Foster an enthusiastic love of gardening through our interactions with the community, our commitment to ongoing training and with each other.

  • Commit to creating, managing and maintaining garden projects in the public view, annually reviewing the projects for their value to the community and for their alignment to our mission.

Ozaukee Master Gardeners (OzMG) have more than 80 Master Gardener volunteers who contribute over 7,000 hours annually to a variety of projects and activities. We are a non-profit organization that meets regularly and are governed by an elected Executive Board. Our major fundraising event is our annual Plant Sale. Funds raised at this and other OzMG sponsored events support our programs and projects.
