However, the western mountains are not nearly as extensive, and the more southern latitude means that the climate is warmer. South Carolina is divided into the Piedmont and the Coastal Plain. The border of the two regionS is roughly from the eastern boundary of Aiken County, through central Chesterfield County, to the North Carolina border. The western edge of the Coastal Plain is known as the Sandhills. On the average, rainfall is the heaviest in July and the lightest in November.
Thunderstorms are frequent in the summer.
The shortest growing season in South Carolina is just under 200 days. Along the southern coast of the state, the growing season averages 300 days. The soil of the Piedmont and Coastal Plain is essentially the same as that described for North Carolina. Common Bermudagrass is one of the most widely used grasses. Carpetgrass is useful where the soil is too wet or infertile for Bermudagrass, even though it does not make the most handsome lawn.
