Master Gardeners

The St. Charles County Master Gardeners are trained individuals who enjoy learning and sharing their expertise with others. Our gardening backgrounds range from hobbyist to professional, from beginner to experienced, from young adult to senior citizen. The common bond is a love of gardening, learning and sharing. More training info.

After training, Master Gardeners serve as a resource with University of Missouri Extension to give county residents research-based answers to their gardening questions. The primary purpose of a Master Gardener is to volunteer, but members rate camaraderie and learning opportunities as important reasons for participating.
