Master Gardener

Welcome to Charles County Master Gardeners

Master Gardeners are trained volunteers who are passionate about the environment and community engagement. Our mission is to support the University of Maryland Extension service by educating residents about safe, effective and sustainable horticultural practices that build healthy gardens, landscapes, and communities. We use a variety of activities to provide horticulture information such as:

  • Plant clinics to diagnose disease and/or pest problems

  • Exhibits at local events

  • Youth programs

  • Maintaining demonstration gardens

Actions you can take to garden more sustainably include:

  • Composting

  • Growing more native plants

  • Implementing Bay-Wise landscaping practices  

  • Growing food organically

To see what we are currently working on, please visit our Resource Page to get The Compost, for the latest information on new and ongoing projects.

If you or your organization in Charles County would like assistance with planting techniques, or design, or would like to request a gardening presentation, please complete this form.
