Q.Ground Cover For Red Clay Soil
We are moving to Tryon North Carolina and need to know about gardening and landscaping for red clay soil
Let's start with your winter hardiness zone which is 7b. Typically, soils in the area are acidic although I am a big fan of getting soil tested when starting in a new garden. North Carolina extension service. has extensive information on growing in the different areas of NC and they do inexpensive soil tests. Here are some links that I hope you find valuable.
