Demonstration Gardens

Master Gardeners maintain demonstration gardens at several locations in the county showcasing examples of what Montgomery County home owners can do in their own yards.

The Master Gardener Demonstration Garden is located at the Agricultural History Farm Park in Derwood, Md. There are 13 themed gardens and work areas within the approximately quarter acre site. The Garden is open to the public dawn to dusk throughout the year for self-guided tours. No animals inside the Garden please! 

Guided tours with a Master Gardener are available during our growing season, April to the end of October. Schools or other groups interested in scheduling guided tours with a Master Gardener should call 301-590-2842 Monday through Friday 9 a.m. to 1 p.m., April through October. (Please note that this phone number is not checked daily for messages but it is regularly checked.) The Demonstration Garden is also open with Master Gardeners present during the Grow It Eat It event in May and the Harvest Festival in October.

Montgomery County Master Gardeners Demonstration Garden at Agricultural History Farm Park

The Master Gardener Montgomery County Fairgrounds Garden is located at the Montgomery County Agricultural Farm Park in Gaithersburg, MD. During the annual Montgomery County Agricultural Fair in August, thousands of people tour the award-winning gardens located near Old MacDonald's Barn. Master Gardener volunteers also maintain the beds at the nearby Heritage House and the 4H Garden located outside the Chilly Mall.

Montgomery County Master Gardeners volunteer at the National Library of Medicine Herb Garden at the National Institutes of Health campus in Bethesda, MD. This is a demonstration garden of medicinal herbs, so plants are labeled with their historic medicinal uses. As Master Gardeners, we educate visitors about herbs, their uses, medical history, and gardening practices.

Master Gardeners volunteer at the Audubon Naturalist Society Woodend Sanctuary’s Learning Garden in Chevy Chase. Visitors to the garden include hundreds of school and summer camp children as well as adults, who come for the ANS environmental education programs. The Master Gardeners collaborate with ANS to cultivate and maintain the Children’s Garden that consists of 5-6 raised garden beds. MG volunteers also assist in the child-centered garden activities that are conducted during the camp sessions, and conduct several open houses for the public each growing season on selected topics of sustainable gardening practices.

Master gardeners volunteer at the USO Warrior and Family Center on the Walter Reed National Military Medical Center campus in Bethesda which hosts educational and recreational events for active duty military and their families. The garden surrounding the center, completed in 2014, is designed as a healing garden where service members can relax and rehabilitate. Master Gardeners started their work in the Walter Reed USO Healing Garden in 2018 rehabilitating the planted beds, directing corporate volunteers to help clean up and maintain the garden as well as working with the hospital's recreational therapists in their Psychiatric Continuity Services Horticulture program.  Our program is working to broaden our activities to include special events in the garden for service members and their families.
