Welcome to the Clemson Extension Tri-County Master Gardener Association website! The TCMGA is a non-profit organization made up of dedicated volunteers from Berkeley, Charleston, and Dorchester counties who are trained by the Clemson Extension Service to support the local county extension agent. All those who successfully complete the required Master Gardener Training Course are members of the Tri-County Master Gardener Association.
Master Gardener Volunteers are available year-round to answer your gardening questions. We volunteer throughout the entire Tri-County area, providing research based information to the public in all areas of gardening and horticulture. Particular attention is paid to conserving and protecting the environment using sustainable practices and advocating the proper use of pesticides, herbicides, and fertilizers.
Tri-County Master Gardeners are available Monday through Friday in all three county extension offices to answer your gardening questions, and often on weekends at our “Ask a Master Gardener” events. At times, you may be asked to bring in a sample of that annoying bug, pesky weed, diseased branch or flower, or your diseased turf grass. If so, simply place your sample in a zip-lock bag and bring it in for us to identify. All insects must be in a container of alcohol. If we are unable to identify your problem, we will send it to the experts at Clemson. Your answers to the day to day questions about gardening are just a phone call away.

For the safety of our volunteers and the general public, Clemson Extension has closed the Charleston and Berkeley County Extension offices until further notice. The Summerville Master Gardener Volunteer office at Summers Corner is closed as well. All soil samples need to be mailed directly to the Clemson Agricultural Services Lab, with payment (cash or check), and a Soil Sample form filled out. For further instructions, please click here. If you need help, please send an email to email@example.com. Someone will get back to you as soon as possible!
