Dent Corn
Dent corn is typically grown for animal feed, cornmeal, or ethanol production. It’s not typically eaten fresh, but it can be dried and ground into flour. This variety gets its name from the “dent” that forms in the top of the kernel as it dries.
- Yellow Dent: The most common variety, used for making cornmeal and animal feed.
- Indian Corn: Known for its colorful, multi-hued kernels, it’s often used for decoration or ground into flour.
Flint Corn
Flint corn is a hard, starchy corn that’s often used in traditional dishes like polenta and cornmeal. It has a tougher kernel, making it suitable for grinding into flour.
- Glass Gem: A beautiful, multi-colored corn variety that is highly decorative but also good for grinding into cornmeal.
Preparing the Soil for Growing Corn
The success of your growing corn venture begins with proper soil preparation. Corn is a heavy feeder, meaning it requires rich, fertile soil to grow. Follow these steps to prepare the soil for planting corn:
Step 1: Choose the Right Location
Corn requires full sunlight to thrive, so choose a location in your garden that receives at least 6-8 hours of direct sunlight per day. Growing corn in a sunny spot will ensure strong, healthy plants.
Step 2: Test the Soil
Before planting, test your soil’s pH level. Corn prefers slightly acidic to neutral soil, with a pH between 5.8 and 7.0. You can buy a soil testing kit or send a sample to a local agricultural extension office to get a detailed analysis of your soil.
Step 3: Amend the Soil
Corn thrives in rich, well-draining soil. Add compost, well-rotted manure, or a balanced fertilizer to improve the soil’s fertility. If your soil is heavy clay, consider adding organic matter or sand to improve drainage. Incorporating organic matter into your soil also increases its ability to retain moisture, which is essential for growing corn successfully.
Step 4: Create Rows
Corn needs space to grow. Create rows that are 30-36 inches apart to allow the corn plants to spread. If you’re planting multiple rows, stagger them so that the plants can cross-pollinate effectively. Corn is wind-pollinated, so planting in blocks rather than single rows increases the chance of good pollination.
Planting Corn
Now that your soil is prepared, it’s time to plant your corn. Planting growing corn properly is essential for getting a healthy crop. Here’s how to plant your corn seeds correctly.
Step 1: When to Plant
The best time to plant corn is in late spring or early summer, once the soil temperature reaches at least 60°F (15°C). Corn needs warm soil to germinate and grow, so wait until the danger of frost has passed before planting.
Step 2: Planting Depth and Spacing
Plant corn seeds about 1-2 inches deep. Space the seeds 6-8 inches apart within the rows. If you’re planting multiple rows, make sure the rows are 30-36 inches apart to allow for adequate air circulation and room for the corn to grow.
Step 3: Watering After Planting
Water the corn seeds thoroughly after planting. Corn requires consistent moisture, especially during the germination phase. However, avoid overwatering, as this can lead to root rot. Keep the soil evenly moist, but not soggy, to help the seeds sprout and establish strong roots.
Caring for Corn Plants
Once your corn seeds have germinated, it’s time to focus on care. Growing corn requires ongoing attention to ensure healthy plants and a bountiful harvest. Here’s what you need to do to care for your corn throughout the growing season.
Step 1: Watering
Corn is a thirsty plant, and it needs about 1-1.5 inches of water per week, especially during the growing and pollination phases. Water deeply and consistently, especially during dry spells, to keep the soil moist.
Step 2: Fertilizing
Corn is a heavy feeder, meaning it requires a lot of nutrients throughout its growing season. Apply a high-nitrogen fertilizer when the plants are about a foot tall to promote healthy growth. If you’re growing sweet corn, consider using a balanced fertilizer to avoid excessive leaf growth at the expense of kernels.
Step 3: Mulching
Applying mulch around your corn plants can help retain moisture, suppress weeds, and keep the soil temperature stable. Use organic mulches like straw or grass clippings to prevent the soil from drying out too quickly.
Step 4: Weed Control
Weeds can compete with your corn for nutrients and water, so it’s important to keep your garden free of weeds. Hand-pulling or using a hoe to remove weeds is the most effective way to control them without damaging your corn plants. Be careful not to disturb the shallow roots of your corn when weeding.
Pollination and Growing Corn
Pollination is critical for growing corn, especially for the production of ears with full kernels. Since corn is wind-pollinated, you need to ensure proper pollination for a good harvest.
Step 1: Encouraging Pollination
To help with pollination, plant your corn in blocks or groups rather than single rows. This makes it easier for the wind to carry pollen from one plant to another. If the weather is calm and there’s not enough wind, you can gently shake the plants to encourage pollination.
Step 2: Signs of Successful Pollination
You’ll know pollination has occurred when the silk at the top of each ear turns brown and dry. If you notice that the ears are missing kernels, this may indicate poor pollination, and you may need to try hand-pollination in the future.
Harvesting Corn
Growing corn culminates with a rewarding harvest. Knowing when to harvest your corn is crucial to ensure it’s at its peak for eating, storing, or processing.
Step 1: When to Harvest
Sweet corn is typically ready to harvest 75-100 days after planting. The best time to pick sweet corn is when the kernels are plump and the silk has turned brown. For popcorn or field corn, you’ll need to wait until the kernels are completely dried out on the cob.
Step 2: How to Harvest
To harvest your corn, simply grab the ear and twist it down and away from the stalk. For sweet corn, husk the ear immediately and cook it fresh. For dried corn, leave the ears on the stalks until fully dry, then remove them for storage.
Conclusion
Growing corn can be a fun and rewarding experience, whether you’re planting sweet corn, popcorn, or field corn. With the right soil, proper care, and attention to pollination, you can successfully grow a variety of corn in your garden. From selecting the right variety to harvesting your crop at the perfect time, each step of the process brings you closer to
