We work with youth groups for the "Grow-It-Eat-It" program. Our farm includes demonstration, pollinator, and herb gardens, and a food forest. Located at American Chestnut Land Trust.
GARDEN SMARTER - This award winning educational program allows Master Gardeners to share their knowledge and experience with the community.

We will also have Master Gardener representatives from Bay-Wise, and Plant Sale. There will be an information table for any gardening questions. Registration will be at the door, the day of the event.

Part of being a Calvert County Master Gardener is constantly learning about new horticultural advances. In fact, each Master Gardener is required to complete a minimum of 10 hours of approved continuing education each year in order to maintain the status of Active Master Gardener.
Continuing education hours may be completed through classes, webinars, and other educational opportunities offered by UME, eXtension, nature centers etc.
Viewings in the Prince Frederick office are POSTPONED, please check back for updates.
What is the Backyard Buffer Program?
The Backyard Buffer program is supported by the Maryland DNR Forest Service and the Calvert County Master Gardeners with its partner the American Chestnut Land Trust, and provides Calvert County homeowners free tree seedlings to create a native riparian forest buffer in their backyard. Calvert County landowners who have a creek, drainage ditch, stream or other waterway on or near their property are eligible for free trees through the Department's Backyard Buffers program.
Trees intercept rainfall, reducing its impact and allowing the soil to absorb water instead of running off into streams. Trees planted along waterways help improve water quality by absorbing excess nutrients, lowering peak water temperatures, reducing sediment and stabilizing stream banks.
