Choosing the Right Corn Variety

Sweet Corn Varieties:

Sweet corn is a popular choice for home gardens, prized for its delectable taste when harvested fresh. Varieties like 'Ambrosia,' 'Honey Select,' and 'Kandy Korn' are known for their sweetness and tenderness.

Flour Corn Varieties:

Flour corn, also known as maize, is often used for making cornmeal or flour. 'Hopi Blue' and 'Floriani Red Flint' are heirloom varieties with unique colors and excellent milling properties.

Popcorn Varieties:

If you fancy growing your popcorn for movie nights, consider varieties like 'Hulless Baby White' or 'Robust Yellow.' These varieties are bred specifically for their popping qualities.

Ornamental Corn Varieties:

For decorative purposes, ornamental corn varieties add a splash of color to your garden. 'Indian Ornamental' and 'Strawberry Popcorn' are popular choices for both aesthetic appeal and functionality.


Preparing the Soil

Sunlight Requirements:

Corn is a sun-loving crop. Pick a spot in your garden with six to eight hours of direct sunlight daily. Adequate sunlight ensures robust growth and good kernel development.

Well-Drained Soil:

Corn prefers well-drained soil with a slightly acidic to neutral pH range of 6.0 to 7.0. Amending the soil with organic matter like compost enhances fertility and water retention.

Soil Temperature:

Wait until the soil temperature reaches around 50°F (10°C) before planting corn seeds. Cold soil can impede germination, and corn thrives in warmer conditions.

Spacing and Rows:

Corn is wind-pollinated, so plant it in blocks rather than single rows to ensure proper pollination. Space the seeds about 9-12 inches apart in rows that are 30-36 inches apart.


Planting Corn Seeds

Direct Sowing:

Corn is best grown directly from seeds in the garden. Plant the seeds about 1-2 inches deep, ensuring proper spacing. If you're planting multiple rows, make sure there's enough distance for pollination.

Successive Plantings:

To extend the harvest period, consider successive plantings every 2-3 weeks. This staggered approach ensures a continuous supply of fresh corn throughout the growing season.

Companion Planting:

Planting beans and squash alongside corn, known as the "Three Sisters" method, is a traditional Native American technique that enhances each other's growth. Beans fix nitrogen in the soil, benefiting corn, while squash provides ground cover, suppressing weeds.

Caring for Your Corn Crop


Corn needs constant moisture, particularly during the critical stages of tasseling and silking. Water deeply, providing at least 1-1.5 inches of water per week. Drip irrigation or soaker hoses are excellent choices to keep the soil consistently moist.


Corn is a heavy feeder, so supplement the soil with balanced fertilizer before planting. Side-dress with nitrogen when the plants are knee-high and again when they begin to tassel. A well-balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable.

Weed Control:

Keep the corn patch free of weeds, especially during the early stages of growth. Mulching helps suppress weeds and retains soil moisture. Be mindful not to damage the shallow corn roots when cultivating around the plants.

Hilling Soil:

As corn plants grow, consider hilling soil around the base of the stalks. This practice provides stability to the tall plants and encourages additional root development.


Dealing with Common Pests and Diseases

Corn Earworms:

Corn earworms can be a common pest. Monitor the tips of the ears for signs of infestation, and consider applying a biological pesticide or introducing natural predators like trichogramma wasps.

Corn Smut:

Corn smut is a fungal disease that manifests as large, swollen galls on the ears. Remove and destroy infected plants promptly to prevent the spread of spores.


Birds may pose a threat to ripening corn. Protect ears by covering them with paper bags or placing netting over the plants. Harvesting slightly earlier than peak ripeness can also deter bird damage.


Harvesting Corn

Observing Signs of Ripeness:

The key to harvesting corn is to observe signs of ripeness. Ears should be filled to the tip with plump, well-developed kernels. The silks at the top should be brown and dry.

Harvesting Time:

Harvest corn when the kernels are in the "milky" stage for sweet corn. Popcorn should be left on the stalk until the husks are completely dry. Harvest flour corn when the kernels are hard and fully mature.

Gentle Harvesting:

To harvest, grasp the ear firmly and pull downward with a slight twisting motion. Harvesting should be done in the early morning when the sugar content is at its peak.

Post-Harvest Care:

Once harvested, corn should be consumed or preserved promptly for the best flavor. If not eating immediately, store corn in the refrigerator to retain its sweetness.
