DEMONSTRATION GARDENS - The Demonstration Gardens have been Bay Wise Certified, demonstrating ecologically sound gardening practices to restore the habitat to benefit plants, pollinators, wildlife, and ultimately, humanity.
Located at the Community Resource Building (CRB) across the street from the Prince Frederick Post Office.

DOUBLE OAK FARM DEMONSTRATION AND VEGETABLE GARDEN - Volunteers raise and nurture vegetables in a natural way for soil regeneration, and donate them to local food pantries. We work with youth groups for the "Grow-It-Eat-It" program. Our farm features demonstration, pollinator, and herb gardens, as well as a food forest. Located at the American Chestnut Land Trust.

GARDEN SMARTER - This award-winning educational program allows Master Gardeners to share their knowledge and experience with the community. Attendees have the opportunity to ask questions, learn best management practices, and share ideas. The program begins in January with a Community Seed Swap where vegetable, herb, annual flower, and native plant seeds will be available for exchange.

2024 Garden Smarter Lecture Schedule

SEED SWAP - 2026 Seed Swap will be held on January 17th from 10:00 AM - 12:00 PM at the Twin Beach Library. We will have seeds in the following categories: Vegetables (warm and cool vegetables), herbs, native perennial flowers, annual/perennial flowers, and older seeds of all kinds. We will also have Master Gardener representatives from Bay-Wise and the Plant Sale. There will be an information table for any gardening questions. Registration will be available at the door on the day of the event.

Bring your packaged seeds you no longer need to the seed swap (saved or bought for 2022-2025). We are unable to accept any unpackaged seeds.

GUILD AT CALVERT MARINE MUSEUM - Master Gardeners partner with museum staff to educate the public about good landscaping practices to control storm water runoff, encourage use of native plants, and use integrated pest management practices. Furthermore, composting and effective, sustainable horticultural practices are demonstrated.

NORTH BEACH FARMERS' MARKET INFORMATION TABLE - Displays materials for the CCMG Information Table at the North Beach Farmers’ Market to inform residents about all the programs offered by the CCMG. 2025 schedule (times may vary) April to October Sat: 8:00 a.m. - 11:30 a.m. The farmers' market is located at the parking lot of the North Beach Senior Center.

PLANT SALE - The CCMG Plant Sale has become known as a source for native plants and organically grown vegetable plants. The Plant Sale is held on the first Saturday in May in the parking lot of the CRB. Educational workshops, tours, and a bake sale are also part of the day’s activities.

PROJECT SPUDNIK AT ALL SAINTS EPISCOPAL CHURCH - Youth come together to grow potatoes and other vegetables in containers. The food is donated to area food banks. Participants learn about composting, soil composition, how to improve it, as well as how to prevent and control diseases, and create companion plant & pollinator gardens.

RAIN GARDEN & STORM WATER MANAGEMENT AT OLIVET UNITED METHODIST CHURCH - The project covers storm water management, planting of a rain garden, and installation of native plants to support pollinators in the community.

YOUTH GARDENS AT ANNMARIE GARDENS - The CCMGs developed these gardens as teaching tools for the public and as part of the Annmarie Youth Summer Camp, where we instruct children about gardening, nature, and nutrition. The vegetables are donated to local food banks.

Educational Opportunities

Being a Calvert County Master Gardener involves continually 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 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, and other related organizations.

Viewings in the Prince Frederick office are POSTPONED. Please check back for updates.

Backyard Buffers Program

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. It provides Calvert County homeowners with 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.
