University of Maryland Extension Master Gardener Program

The University of Maryland Extension Master Gardener Program trains volunteer horticultural educators to promote safe, effective, and sustainable gardening practices throughout Maryland. Operating through county-based programs and Baltimore City, this initiative empowers residents to create healthy gardens and landscapes while building stronger communities. Master Gardeners provide educational support through plant clinics, demonstration gardens, speaking engagements, and specialized programs like Bay-Wise Certification for water quality protection in the Chesapeake Bay watershed. The program connects Maryland residents with expert horticultural knowledge through Ask Extension services, the Maryland Grows Blog, and the Home and Garden Information Center, all dedicated to advancing science-based gardening education and integrated pest management for improved human and environmental health.
