Best Cash Crops To Grow In South Carolina : Warm Season Peanuts For South Carolina

South Carolina’s long, humid summers give growers an edge with heat-loving plants that northern farmers struggle to cultivate. When you’re looking for the best cash crops to grow in South Carolina, you need plants that thrive in the state’s clay-heavy soil, high humidity, and extended growing season. From traditional row crops to niche specialty plants, the Palmetto State offers real profit potential for farmers who pick the right crops.

This guide covers the top money-making crops for South Carolina’s climate, soil, and market conditions. You’ll get practical advice on what to plant, when to plant it, and how to maximize your return per acre.

Best Cash Crops To Grow In South Carolina

South Carolina’s agricultural sector generates over $10 billion annually, and the state ranks among the top producers for several key crops. The warm climate, ample rainfall, and long frost-free season (typically 200-250 days) make it ideal for a wide range of cash crops. Here are the most profitable options.

1. Tobacco

Tobacco has been a cornerstone of South Carolina agriculture for centuries. The state currently ranks 4th in the nation for tobacco production, with over 20,000 acres planted annually. Flue-cured tobacco is the primary variety grown here.

Why it works:

  • High value per acre: Tobacco can yield $3,000 to $5,000 per acre
  • Strong market demand from cigarette and cigar manufacturers
  • Well-suited to the sandy loam soils found in the Pee Dee region

Growing tips:

  1. Start seeds in greenhouses 6-8 weeks before last frost
  2. Transplant seedlings in April or early May
  3. Harvest begins in July and continues through September
  4. Cure leaves in specialized barns for 6-8 weeks

One thing to watch out for: tobacco requires significant labor and equipment. You’ll need a curing barn and harvest help. But if you have the resources, it remains one of the most profitable cash crops in the state.

2. Soybeans

Soybeans are the most widely planted cash crop in South Carolina, covering over 400,000 acres. They’re relatively low-maintenance and have a steady market for animal feed, biodiesel, and human consumption.

Key benefits:

  • Low input costs compared to corn or cotton
  • Good rotation crop that fixes nitrogen in the soil
  • Drought-tolerant once established
  • Multiple market channels: grain elevators, processors, and export

Planting schedule:

  1. Plant from mid-April through early June
  2. Choose maturity groups V through VII for South Carolina
  3. Harvest from October through November
  4. Average yield: 30-50 bushels per acre

Prices flucuate with global markets, but soybeans consistently provide a reliable income stream. Many farmers use them as a base crop to cover operating costs while taking more risk on specialty crops.

3. Cotton

Cotton remains a major cash crop in South Carolina, especially in the coastal plains and Pee Dee regions. The state grows about 200,000 acres of cotton each year, primarily upland varieties.

Why cotton works here:

  • Long growing season (150-180 days) matches cotton’s needs
  • Hot, humid summers promote boll development
  • Strong demand from textile mills and export markets
  • Can yield 800-1,200 pounds of lint per acre

Critical steps:

  1. Plant in late April to early May when soil temps reach 60°F
  2. Monitor for boll weevils and bollworms (use IPM strategies)
  3. Apply defoliant in September to prepare for harvest
  4. Pick with a cotton stripper or picker in October

Cotton prices have been volatile in recent years, but the crop’s versatility (lint for fiber, seeds for oil and feed) provides multiple revenue streams. If you have the equipment, it’s a solid choice.

4. Peanuts

South Carolina is the 6th largest peanut-producing state in the U.S., with over 100,000 acres planted. Peanuts thrive in the state’s sandy soils and warm temperatures.

Profit potential:

  • Average yield: 3,000-4,000 pounds per acre
  • Prices range from $400 to $600 per ton
  • Strong demand from snack food companies and peanut butter makers
  • Government support through the Farm Bill helps stabilize prices

Growing guide:

  1. Plant after last frost (late April to mid-May)
  2. Use well-drained sandy loam soil with pH 5.8-6.2
  3. Inoculate seeds with rhizobium bacteria for nitrogen fixation
  4. Dig and invert vines in September or October
  5. Dry peanuts to 10% moisture before storage

Peanuts are a high-value crop, but they require specialized harvesting equipment (a digger and combine). If you’re already set up for row crops, adding peanuts can diversify your income.

5. Corn

Field corn for grain and silage covers about 300,000 acres in South Carolina. While not as profitable per acre as tobacco or peanuts, corn offers consistent demand and multiple uses.

Market options:

  • Grain for livestock feed or ethanol production
  • Silage for dairy and beef operations
  • High-moisture corn for on-farm feed

Best practices:

  1. Plant from mid-March to early April for full-season varieties
  2. Use hybrid seeds suited to the Southeast (120-125 day maturity)
  3. Apply nitrogen fertilizer at planting and side-dress
  4. Harvest grain at 15-20% moisture in August-September

Corn prices are tied to commodity markets, so watch futures prices before planting. It’s a good rotation crop with soybeans and cotton, and it can be a reliable base for your farm income.

6. Watermelons

South Carolina ranks 5th in the nation for watermelon production, with over 10,000 acres harvested annually. The state’s long, hot summers are perfect for this vine crop.

Why watermelons work:

  • High value per acre: $2,000-$4,000 potential
  • Strong local and regional demand (farmers markets, grocery chains)
  • Can be direct-marketed for premium prices
  • Multiple varieties: seedless, seeded, mini, and yellow-fleshed

Planting and harvest:

  1. Plant after last frost (April) when soil is 70°F
  2. Space plants 3-4 feet apart in rows 6-8 feet apart
  3. Use drip irrigation and plastic mulch for weed control
  4. Harvest 80-100 days after planting, when tendril dries

Watermelons are labor-intensive at harvest, but the profit margin can be excellent. Many small farmers start with a few acres and scale up as they build market relationships.

7. Sweet Potatoes

Sweet potatoes are a rising star in South Carolina agriculture. The state now grows over 5,000 acres, with demand increasing for fresh market and processing.

Advantages:

  • Heat-tolerant and drought-resistant once established
  • High yields: 300-500 bushels per acre
  • Prices range from $15 to $25 per bushel
  • Growing popularity for health-conscious consumers

Growing steps:

  1. Plant slips (rooted cuttings) in May after soil warms
  2. Use raised beds for better drainage
  3. Control weeds early with cultivation or herbicides
  4. Harvest in September-October before frost
  5. Cure at 85°F and 90% humidity for 7-10 days

Sweet potatoes require specialized harvesting equipment (a chain digger) and curing facilities, but the returns are worth it. The Covington and Beauregard varieties perform well here.

8. Peaches

South Carolina is the 2nd largest peach producer in the U.S., behind only California. The state grows over 20,000 acres of peaches, primarily in the Ridge region near Edgefield and Saluda.

Why peaches thrive:

  • Chilling hours (400-800) are adequate for most varieties
  • Sandy loam soils with good drainage
  • Hot summers develop high sugar content
  • Strong direct-market potential (you-pick, farm stands)

Orchard establishment:

  1. Plant dormant trees in late winter (February-March)
  2. Space trees 18-20 feet apart in rows
  3. Prune annually for shape and fruit production
  4. Thin fruit in spring for larger, better-quality peaches
  5. Harvest from May through September, depending on variety

Peaches are a long-term investment (3-4 years to first harvest), but established orchards can produce for 15-20 years. The profit per acre can exceed $5,000 in good years.

9. Strawberries

Strawberries are a high-value crop for small and medium farms in South Carolina. The state’s mild winters allow for annual hill plasticulture systems.

Profit factors:

  • High price per pound: $3-$5 retail
  • Short growing season (April-May) fits into rotation
  • Direct-marketing opportunities (U-pick, farmers markets)
  • Can gross $20,000-$30,000 per acre

Planting guide:

  1. Set out dormant plants in September-October
  2. Use raised beds with drip irrigation and plastic mulch
  3. Overwinter with row covers for frost protection
  4. Harvest from April through May
  5. Renovate beds after harvest or rotate to new ground

Strawberries are labor-intensive (planting, picking, weeding), but the profit per acre is hard to beat. Many growers combine them with other berries for a diversified fruit operation.

10. Hemp

Industrial hemp was legalized in 2018, and South Carolina farmers have been testing this crop. While the market is still developing, hemp offers potential for fiber, grain, and CBD production.

Current status:

  • Licensed acreage has grown each year
  • CBD hemp can yield $5,000-$10,000 per acre (volatile)
  • Fiber hemp is lower value but more stable
  • Grain hemp for seed oil and protein is emerging

Considerations:

  1. Apply for a state license through the SC Department of Agriculture
  2. Choose varieties with less than 0.3% THC
  3. Plant in May-June for full-season growth
  4. Harvest for CBD in September (flowers), fiber in October (stalks)

Hemp is a high-risk, high-reward crop. The market is still maturing, and prices have dropped from early highs. But for innovative farmers, it offers a new income stream.

Factors That Affect Crop Choice

Before you decide on the best cash crops to grow in South Carolina, consider these factors that influence success.

Soil Type

South Carolina has diverse soils, from sandy coastal plains to clay-heavy piedmont. Sandy loams are ideal for peanuts, sweet potatoes, and watermelons. Clay soils work better for corn, soybeans, and tobacco. Get a soil test before planting to know your pH and nutrient levels.

Climate Zones

The state spans USDA zones 7b to 8b. Coastal areas have longer growing seasons (250+ frost-free days) while the upstate has shorter seasons (200 days). Choose crops that match your specific zone. For example, peaches need chilling hours that may be insufficient in the lowcountry.

Market Access

Think about where you’ll sell your crop. Proximity to processing plants, grain elevators, farmers markets, or urban centers affects profitability. The I-95 corridor and coastal areas offer good market access for fresh produce.

Equipment And Labor

Some crops (tobacco, strawberries, watermelons) are labor-intensive. Others (soybeans, corn) can be mechanized. Assess your available labor and equipment before committing. Leasing equipment or hiring custom harvesters can reduce capital costs.

Rotation Strategies For Maximum Profit

Rotating crops improves soil health and reduces pest pressure. Here’s a sample 3-year rotation for South Carolina.

  • Year 1: Corn (heavy feeder) followed by winter cover crop
  • Year 2: Soybeans (nitrogen fixer) or peanuts
  • Year 3: Cotton or tobacco (clean cultivation)

For vegetable growers, rotate between solanaceous crops (tomatoes, peppers) and cucurbits (watermelons, squash) to avoid disease buildup. Always include a cover crop like rye or crimson clover in the off-season.

Financial Considerations

Starting a farm or adding a new crop requires capital. Here are typical startup costs for some crops.

  • Tobacco: $3,000-$5,000 per acre (includes curing barn)
  • Soybeans: $200-$300 per acre (seed, fertilizer, chemicals)
  • Watermelons: $1,500-$2,500 per acre (plastic, drip, plants)
  • Peaches: $5,000-$8,000 per acre (trees, trellis, irrigation)

Apply for USDA programs like the Environmental Quality Incentives Program (EQIP) for cost-share on conservation practices. Also check with the SC Department of Agriculture for state-level grants.
