Who are We?
The Richland County Master Gardener Association (RCMGA) is a not-for-profit organization composed of volunteers whose goal is to promote and teach environmentally sound, research-based gardening practices to the citizens of Richland County, and to provide education to our members needed to accomplish our purpose. Our members have completed a Master Gardener program conducted by state extension service. We serve our county through such activities as assisting in the county extension office, giving educational programs to the public, and participating in community projects related to gardening.
We offer a RCMGA Scholarship for the Clemson Master Gardener Program.
