South Carolina produces a wide range of crops thanks to its long growing season, humid subtropical climate, and varied terrain stretching from coastal lowlands to Blue Ridge foothills. Cotton, soybeans, corn, peanuts, peaches, leafy greens, and assorted vegetables all have a place in the state’s agricultural economy, and the specific mix shifts depending on which part of the state you’re looking at.
Cotton Remains the Flagship Row Crop
Cotton has deep roots in South Carolina, and it is still one of the state’s most valuable cash crops. Farmers grow it across multiple physiographic regions, from the sandy soils of the Coastal Plain to heavier upland fields. A multi-year study of 50 commercial cotton trials spanning four of the state’s physiographic regions found that lint yield responded to nitrogen fertilization in about half the trials, and the economically optimal nitrogen rate varied widely depending on previous crops, tillage type, and water management.1Agronomy Journal. Cotton lint yield responses to nitrogen fertilization are diverse in South Carolina That variability speaks to just how different growing conditions can be from one field to the next, even within the same county.
Most of the state’s cotton acreage sits in the Coastal Plain, where warm temperatures and a long frost-free season favor the crop. Upland cotton varieties dominate, and the harvest typically runs from late September through November. Cotton competes with soybeans and corn for field space each year, with farmers rotating among the three based on commodity prices and soil health goals.
Soybeans, Corn, and Wheat
After cotton, soybeans and corn are the two largest row crops in South Carolina by planted acreage. Soybeans thrive in the state’s warm summers and are often rotated with corn or cotton to replenish soil nitrogen naturally. Corn is grown both for grain and as silage to feed the state’s livestock operations, particularly poultry and dairy cattle. Wheat plays a smaller but still important role as a winter cash grain. Many farmers plant wheat in the fall, harvest it in late spring, and then follow with a summer crop like soybeans in a double-cropping system that squeezes two harvests from one field in a single year.
These row crops collectively dominate the agricultural landscape of the Midlands and Pee Dee regions. The Pee Dee, in the northeastern part of the state, is particularly productive farmland, with deep, fertile soils and access to river water for irrigation.
Peanuts in the Carolina Belt
South Carolina sits at the southern edge of the Virginia-Carolina peanut belt, and the crop matters to the state’s agricultural mix, particularly in the southern Coastal Plain counties. Runner and Virginia-type peanuts are the main varieties. Harvesting peanuts involves a two-step process: digging the plants and inverting them to dry, then running a combine through the windrows. Timing that sequence is one of the biggest challenges growers face. A survey of 166 farmers across North Carolina, South Carolina, and Virginia found that growers weigh pod maturity just as heavily as soil conditions and the threat of tropical weather when deciding when to dig.2Crop, Forage & Turfgrass Management. Farmer insights on harvesting peanut: A survey from the Virginia–Carolina region of the United States Digging too early sacrifices yield, while waiting too long risks losing the crop to a late-season storm.
Peanuts also earn their place in crop rotation because they fix nitrogen in the soil, reducing fertilizer costs for the next season’s corn or cotton. The sandy, well-drained soils of the southern Coastal Plain are naturally suited to peanut production, and the crop can be profitable on land that struggles with other row crops.
Peaches and the Piedmont
South Carolina has long been one of the top peach-producing states in the country, and the fruit is closely tied to the state’s identity. A peach appears on South Carolina license plates, and the Ridge area of the Piedmont, particularly around the towns of Ridge Spring, Johnston, and Monetta in the Saluda-Edgefield-Aiken county corridor, is the heart of peach country. The slightly elevated terrain provides good air drainage that helps protect blossoms from late spring frosts, and the red clay soils hold moisture well during the growing season.
Peach trees require a certain number of winter chill hours below roughly 45°F to break dormancy and produce fruit properly. South Carolina’s Piedmont historically provided enough of these chill hours for medium- and high-chill varieties that produce the best commercial fruit. Warming winters, though, have pushed growers to experiment with lower-chill cultivars and adjust orchard management. Beyond peaches, some South Carolina orchards also produce apples in the upstate region near the Blue Ridge, along with smaller plantings of blueberries, strawberries, and muscadine grapes scattered across the state.
Leafy Greens and Vegetables
Collard greens and kale have both cultural and economic significance in South Carolina. Researchers evaluating 14 varieties of collards and kale commonly grown in the region found significant differences in shelf life and nutrient retention among the varieties. Several commercial collard cultivars and an heirloom variety known as the SC Glaze Collard held up especially well during cold storage, maintaining marketability for weeks after harvest.3HortScience. Postharvest Quality of Brassica Leafy Green Accessions Grown in South Carolina That kind of research matters to local growers because shelf life directly determines whether produce can reach distant markets or is limited to nearby farm stands and stores.
Beyond leafy greens, South Carolina farmers produce tomatoes, watermelons, cantaloupes, cucumbers, squash, sweet potatoes, and peppers. Many of these crops are concentrated in the lower Coastal Plain, where the long growing season allows early harvests that command premium prices on East Coast markets. Truck farming, growing vegetables for fresh market sale rather than processing, has a long tradition in the state, especially around Charleston, Beaufort, and the Pee Dee.
Watermelons deserve a special mention. South Carolina regularly ranks among the top watermelon-producing states, and the Hampton County Watermelon Festival, running since 1939, is one of the oldest of its kind in the nation. The crop does well in the sandy, well-drained soils of the southern Coastal Plain, and its harvest in June and July marks the unofficial start of produce season for many communities.
How Geography Shapes What Grows Where
South Carolina packs several distinct agricultural zones into a relatively small state. Understanding those zones helps explain why the crop mix changes so dramatically as you drive from the coast inland toward the mountains.
- Coastal Plain: The largest agricultural zone, stretching from the coast roughly two-thirds of the way across the state. Flat terrain, sandy to loamy soils, and a long growing season make this the center of cotton, soybean, corn, peanut, watermelon, and vegetable production.
- Sandhills: A narrow band of deep, sandy soils running through the middle of the state. Some peach orchards and specialty crops grow here, but the droughty soils limit row-crop yields without irrigation.
- Piedmont: Rolling hills with red clay soils. This is peach and cattle country, with some hay, small grains, and vegetable production. The Ridge area’s orchards sit in this zone.
- Blue Ridge: The mountainous northwestern corner. Apple orchards, cabbage, and cool-season vegetables grow at higher elevations. Most agriculture in this zone is pasture-based for beef cattle.
The interaction between zone and crop is not rigid. Irrigation has expanded the range of crops that can grow profitably in the Sandhills, and cover-cropping practices have improved soil quality in areas that once struggled with row crops. But the basic pattern of row crops dominating the Coastal Plain, tree fruits concentrating in the Piedmont, and cool-season crops favoring the upstate has held for generations.
Irrigation and Water on South Carolina Farms
South Carolina receives plenty of rainfall in most years, but the timing is uneven enough that irrigation has become increasingly important, especially for high-value crops. A mapping study using satellite imagery identified 2,689 center-pivot irrigation systems across the state, covering roughly 146,600 acres. That accounted for over 69% of the state’s total irrigated area and more than 98% of acreage irrigated solely by center pivots.4The Journal of South Carolina Water Resources. Mapping Center Pivot Irrigation Fields in South Carolina with Google Earth Engine and the National Agricultural Imagery Program Most of these pivots covered between 25 and 75 acres, though the largest stretched beyond 300 acres.4The Journal of South Carolina Water Resources. Mapping Center Pivot Irrigation Fields in South Carolina with Google Earth Engine and the National Agricultural Imagery Program
Center-pivot systems are concentrated in the Coastal Plain, where sandy soils drain quickly and crops like corn, cotton, and peanuts benefit from supplemental water during summer dry spells. The Edisto River basin and parts of the Pee Dee region have seen the most growth in irrigated acreage. For vegetable and fruit growers, drip irrigation is more common because it delivers water directly to the root zone and reduces the disease pressure that overhead watering can cause on leaves and fruit.
Tobacco’s Long Decline
Tobacco was once a significant cash crop in South Carolina, particularly in the Pee Dee region, where flue-cured tobacco supported the local economy for most of the twentieth century. That era has largely ended. Researchers documenting the politics of tobacco agriculture in South Carolina from the 1970s through 2009 found that agriculture-based interest groups, elected agricultural officials, and tobacco-district legislators initially formed a tight alliance supporting the industry. Over time, national changes in the tobacco leaf market, including the federal buyout of tobacco quotas in 2004, pushed farm organizations and state agricultural leaders toward a neutral position on tobacco control, even as some legislators remained aligned with manufacturers.5PubMed Central. The changing role of agriculture in tobacco control policymaking: a South Carolina case study
The practical result is that tobacco acreage in South Carolina has shrunk dramatically. Fields that once grew tobacco now produce cotton, soybeans, or sweet potatoes. Some former tobacco barns have been repurposed for curing other products or converted to event venues. The shift away from tobacco is one of the most dramatic agricultural transitions in the state’s modern history, and it happened faster than many Pee Dee farmers expected.
Historical Crops That Built the State
No look at South Carolina agriculture is complete without acknowledging the crops that defined the colonial and antebellum economy. Rice was the original plantation crop of the Lowcountry, grown in tidal and inland swamp fields using the forced labor of enslaved people, many of whom brought rice-growing knowledge from West Africa. By the mid-1700s, South Carolina rice was a major export commodity. The industry collapsed after the Civil War when the labor system that sustained it ended, and hurricanes in the late 1800s destroyed much of the remaining dike infrastructure. Some small-scale heritage rice production has returned in recent years, but it is a tiny fraction of what once existed.
Indigo was the state’s second great colonial crop. When rice prices fell in the 1740s, South Carolina planters shifted toward indigo, which produced a blue dye in demand across the European textile industry. The rise of Carolina indigo was driven not by a monopoly on the British market, which never existed, but by the elastic supply that plantation restructuring made possible, combined with demand for cheap dyestuffs from manufacturers of low-cost textiles at the onset of industrialization. Carolina indigo had a mixed reputation for quality because planters struggled to maintain consistent production standards, but it succeeded in displacing French and Spanish indigo in British and some continental markets.6The Economic History Review. South Carolina indigo, European textiles, and the British Atlantic economy in the eighteenth century The trade collapsed after the American Revolution, when British subsidies disappeared and competition from Asian sources undercut prices.
Sea Island cotton, a long-staple variety prized for its silky fiber, was another historically important crop grown along the coast and on the Sea Islands. It commanded premium prices but required specific coastal conditions and intensive labor. Upland cotton eventually overtook it because upland varieties could grow across a much wider range of the state’s interior.
Specialty and Emerging Crops
Beyond the traditional staples, South Carolina farmers have branched into a variety of specialty products in recent decades. Turf grass, particularly centipede, bermuda, and zoysia sod, is a surprisingly large agricultural product, with sod farms in the Coastal Plain supplying landscaping demand across the Southeast. Nursery plants and greenhouse ornamentals are also significant, driven by the state’s mild climate and proximity to major population centers along the East Coast.
Hemp production received a boost after the 2018 Farm Bill legalized industrial hemp, and South Carolina was among the states that moved quickly to issue growing permits. Early enthusiasm led to a boom in CBD-focused hemp planting, though oversupply and regulatory uncertainty have cooled the market since the initial rush. Some growers are pivoting toward fiber and grain hemp varieties, which have more stable demand but require different processing infrastructure that the state is still building out.
On the smaller end of the scale, farms in the upstate and Piedmont have increasingly turned to agritourism crops: pick-your-own strawberries and blueberries, sunflower fields, pumpkin patches. These operations generate revenue from visitors as much as from the produce itself, often combining crop sales with on-farm events and seasonal festivals. For many small and mid-size operations, the agritourism model has provided an economic lifeline that commodity crops alone could not offer, especially as input costs for fertilizer, fuel, and equipment have climbed.
