How to Grow Corn

Corn is a warm-season crop that can be grown in a variety of climates. It is easy to grow and comes in many varieties, including sweet corn, popcorn, and ornamental corn. Follow this guide to learn how to grow delicious corn in your garden.

What You’ll Need

  • Corn seeds
  • Well-draining soil
  • Compost
  • Watering can or hose
  • Mulch

Choosing the Right Variety

Corn comes in many varieties. Some popular types include:

  • Sweet Corn: Tender and sweet, often eaten fresh or canned.
  • Popcorn: Small, hard kernels that pop when heated.
  • Ornamental Corn: Decorative and often used in crafts and decorations.

Preparing the Soil

Corn prefers well-drained, fertile soil with a pH of 6.0-7.0. Here�s how to prepare your soil:

  1. Loosen the Soil: Till the soil to a depth of 8-10 inches (20-25 cm). Remove any stones or debris that could impede root growth.
  2. Add Compost: Mix in 2-3 inches (5-7.5 cm) of compost to improve soil fertility and structure.

Planting Seeds

Corn seeds can be sown directly into the garden. Here�s how:

  1. Direct Sowing: Plant seeds 1-2 inches (2.5-5 cm) deep in rows spaced 30-36 inches (75-90 cm) apart. Thin seedlings to 12-18 inches (30-45 cm) apart once they have a few true leaves.

Watering and Care

Corn needs consistent watering and care. Follow these tips:

  • Water Regularly: Keep the soil consistently moist, but not waterlogged. Water in the morning to reduce evaporation.
  • Mulch: Apply a 2-3 inch (5-7.5 cm) layer of mulch around the plants to retain moisture and suppress weeds.


Corn benefits from regular fertilization. Use a balanced fertilizer (10-10-10) every 3-4 weeks.


Corn is wind-pollinated, so it�s best to plant it in blocks rather than rows to ensure good pollination. Gently shake the plants when they are in tassel to help disperse the pollen.


Corn is ready to harvest when the ears are plump and the silks have turned brown. Here�s how to harvest:

  • Check Regularly: Harvest corn when the ears are full and the kernels are milky. Use a sharp knife to cut the ears from the stalks.

Storing Corn

Corn can be stored in several ways:

  • In the Fridge: Store fresh corn in the husk in a plastic bag in the refrigerator crisper drawer. Use within 1-2 weeks.
  • Freezing: Blanch corn on the cob in boiling water for 4-6 minutes, then cool in ice water. Freeze in airtight containers for up to 6 months.

Tips and Tricks

  • Succession Planting: Sow seeds every 2-3 weeks for a continuous supply of fresh corn.
  • Companion Planting: Grow corn with beans, squash, or cucumbers to maximize garden space.


Growing corn using these methods will help you achieve a bountiful harvest of delicious, homegrown corn. With proper care and attention, you can enjoy fresh corn from your garden all season long.
