What: Nurture Natives

October 2022 was the inaugural tree and shrub giveaway. On April 29, 2023, Charles County Master Gardeners will once again partner with Nurture Natives at Maryland Day on the University of Maryland campus in College Park. Hundreds of free native shrubs and trees will be distributed to Maryland residents from 10 am – 4 pm.

In late 2021, NCAC, Charles County 4-H, and Charles County Master Gardeners were awarded a grant to train teen pollinator ambassadors. As part of that project, 18 teen ambassadors learned about the importance of pollinators, challenges they face, and ways they can be supported.  Teens used that knowledge to develop fun, interactive activities to teach younger children and adults about pollinators at schools, camps, and outreach events.  Through their efforts a total of 665 people; 447 youth and 218 adults learned about pollination.

Invite a team of Charles County Bay-Wise Master Gardeners to your home to evaluate your landscape and give you advice about native plants, ways to control storm water runoff and other Bay-Wise information.

The Bay-Wise program is a landscape education program that focuses on water quality and conservation efforts in protecting Maryland waterways and the Chesapeake Bay.  It comprises a set of environmental topics, that when used in landscape management, protects the quality and quantity of the water in Maryland.  The program educates homeowners and businesses by providing a landscape yardstick and vegetable garden yardstick identifying best practices.  The landscape owner fills out the yardstick and an application.  The homeowner checks off and receives inches for following best practices.  If the homeowner reaches 36 inches, an appointment is made, and Bay-Wise master gardeners meet with the owner at the property and certify it as a Bay-Wise friendly landscape.
