Demonstration Gardens

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

The Master Gardener Demonstration Gardens, located at the Agricultural Farm History Park in Derwood, MD, are open to the public from dawn until dusk, 365 days a year for self-guided tours. 
To schedule guided tours by a Master Gardener, call 301-590-9650 Monday – Friday, 9 am to 1 pm, March though October. This approximately quarter acre site contains 11 small gardens, each with a different theme.

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 across from 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.
