About the Program

Our Vision

We envision a healthier world through environmental stewardship.

Our Mission

We support the University of Maryland Extension (UME) mission by educating residents about safe, effective and sustainable horticultural practices that build healthy gardens, landscapes, and communities.

Our History

The UME Master Gardener Program began in 1978 as a means to extend research-based knowledge to the general public by providing horticultural and pest management expertise to help protect and improve Maryland’s natural resources. Today, this popular program can be found in 20 Maryland counties and Baltimore City. 

UME Master Gardeners are volunteers who combine their love of plants, people, and the environment to help residents in their communities solve problems and make environmentally-sound decisions.
