ST. MARY'S COUNTY MG PROGRAM

About St. Mary's County Master Gardeners

Our Vision

We envision a healthier world through environmental stewardship.

Our Mission

We support the University of Maryland Extension (UME) mission by educating residents about safe, effective and sustainable horticultural practices that build healthy gardens, landscapes, and communities.

Our History

The UME Master Gardener Program began in 1978 as a means to extend science-based knowledge to the general public by providing horticultural and pest management expertise to help protect and improve Maryland’s natural resources. Today, this popular program can be found in 20 Maryland counties and Baltimore City. 

UME Master Gardeners are volunteers who combine their love of plants, people, and the environment to help residents in their communities solve problems and make environmentally-sound decisions.  

St. Mary’s County Master Gardeners

St. Mary’s County Master Gardeners do a lot to help our community. We host Ask A Master Gardener Plant Clinics where we answer the public’s horticulture questions, conduct Bay-Wise site visits to help educate residents about how to make their landscapes more friendly to the Chesapeake Bay, do many presentations on pollinators, native plants, and other horticulture topics, plus so much more.

Master Gardener Programs

Plant clinics are an opportunity for Master Gardeners to help answer the public’s horticulture questions. We are doing them virtually during covid-19. Please see our Facebook page for Facebook live Plant Clinics and check out the St. Mary’s County Library’s calendar of events to get the link to attend one of our virtual plant clinics!

Before and hopefully after covid-19, we are at the local libraries, farmer’s markets, and more to host plant clinics. People bring us horticulture samples (like plants, insects, tree twigs, etc), pictures of horticulture samples, or just ask us questions. We help answer their questions.

Check back for more updates about plant clinics and when we can return to doing them in person!

  • What is Bay-Wise?

Bay-Wise is a program designed to help Maryland residents learn more about horticulture and landscape practices that are wise about the bay’s health. Maryland Master Gardeners educate Maryland residents about bay friendly practices through presentations, demonstration gardens, one-on-one consultations, home visits, and more. We have also created a “Bay-Wise Yardstick” to help residents see what is and is not Bay-Wise.

  • How Do I Get My Home Landscape or Vegetable Garden Certified as Bay-Wise?

Interested in making your landscape more Chesapeake Bay Friendly? Follow these three steps:

1. Download the appropriate MD Yardstick along with an application

2. Complete the Bay-Wise Maryland Yardstick Application
3. Contact the St. Mary’s County Master Gardeners to sign up for a site visit for certification.  Do not submit your completed Yardstick and application before you contact your local Master Gardener program. 

Once a 'Bay-Wise trained' Master Gardener certifies your home landscape you will receive a small sign to display in your landscape and a certificate. Even if you do not have your landscape certified, you can still do plenty to reduce pollutants going into the Chesapeake Bay by following the suggestions in the Bay-Wise Yardstick.

If you are interested in learning more about the Chesapeake Bay and how our behaviors effect it, please check out the Watershed Stewards Program 

St. Mary’s County Master Gardeners educate St. Mary’s residents about pollinators. Pollinators are very important and proper gardening methods can reduce any harm to them. We have many pollinators in St. Mary’s County such as butterflies, bees, and more! 

Many pollinators prefer native plants and prefer native plants. We have many demonstration gardens around the county that have many pollinator friendly plants that grow well in St. Mary’s such as milkweed, joe pye weed, zinnias, and more! 

Check out our upcoming events page to see when we are having our next educational event on a pollinator related topic!

Composting

St. Mary’s County Master Gardeners educate St. Mary’s residents about composting. We do this through educational presentations, demonstration areas, and more.

Composting is a good way to help reduce waste going to landfills. It is a way put waste to good use! Compost often contains a lot of nutrients that plants need to grow.

There are a lot of plants that produce food that we can grow in St. Mary’s. Some examples are tomatoes, greens, okra, eggplant, squash, rosemary, sage, oregano, thyme, blueberries, raspberries, and more!

St. Mary's County Master Gardeners love native plants! Native plants are plants that were growing here before European settlement. Master Gardeners help educate Maryland residents about how to grow native plants and why they are important.

There are many plants that are native to St. Mary’s County including milkweed, joe-pye weed, andropogon glomeratus, etc… Many species of pollinators co-evolved with native plants and depend on them. We grow many native plants in our demonstration gardens around the county. Check them out at different times of the year to see how pretty and beneficial to our local ecosystem they are!
