Vegetable Planting Dates for South Carolina

South Carolina has three distinct regions: Piedmont in the northwest, Central in the middle part of the state, and Coastal along the coast. Gardeners in one region will have slightly different planting dates from gardeners in other parts of the state. Frost dates in the Piedmont can vary six months from comparable dates on the coast. Knowing the ideal planting dates for your area will ensure your vegetables get off to a good start.
