Optimal Planting Dates

In South Carolina, the ideal time to plant corn varies based on the specific region within the state. Generally, corn should be planted after the last frost date, which can differ across various areas.

Region-Specific Dates:

  • Upstate (Greenville, Spartanburg): Late April to early May
  • Midlands (Columbia, Lexington): Mid to late April
  • Lowcountry (Charleston, Beaufort): Early to mid-April

Using soil temperature as a guideline is also important, as corn germinates best when soil temperatures reach about 50°F (10°C) to 86°F (30°C).

Soil Preparation

Before planting corn, appropriate soil preparation is crucial to ensure healthy growth and high yields. This involves:

  • Testing Soil pH: Aim for a pH between 5.8 and 7.0.
  • Incorporating Organic Matter: Add compost or well-rotted manure to improve soil structure and fertility.
  • Tilling: Break up compacted soil to a depth of 6-8 inches to enhance drainage.

Seed Selection

Selecting the right corn variety is essential for successful cultivation. Factors to consider include:

  • Days to Maturity: Choose varieties that mature within the growing season.
  • Disease Resistance: Look for seeds that are resistant to common diseases in the region.
  • Use: Determine if you want sweet corn for eating, field corn for livestock, or specialty varieties for specific markets.

Recommended Varieties:

Variety Name Type Days to Maturity
Silver Queen Sweet Corn 80-85
