Keep Calm and Garden On!

Welcome to the website of the Howard County Master Gardeners.  The mission of the HowardCounty Master Gardeners is to educate residents about safe, effective, and sustainable horticultural practices that build healthy gardens, landscapes, and communities. The Master Gardener program is administered by the University of Maryland College of Agriculture and Natural Resources Extension Service.

Howard County Master Gardeners are volunteers, trained by the university, who provide horticultural education services to individuals, groups, and communities including government agencies, neighborhood associations, non-profit organizations, historic sites, schools and youth groups, senior citizens and garden clubs. Master Gardener programs and services are available free of charge to all Howard County residents and community groups. 

Certify Your Habitat to Help Wildlife!







Wildlife habitat gardens are a haven for local birds, butterflies, and other wildlife.  Tell us how your yard or garden provides habitat and the National Wildlife Federation will recognize it as a Certified Wildlife Habitat®.

Rake and Take: Got leaves?  Want leaves?
