Growing corn from corn is a rewarding experience that can provide you with fresh, organic produce. Whether you’re a seasoned gardener or a novice, this comprehensive guide will walk you through the entire process, from selecting the right variety to harvesting your bountiful crop.
Selecting the Right Corn Variety
The first step in growing corn is choosing the right variety. There are many types of corn, each with its unique characteristics. Consider the following factors when making your selection:
- Maturity: Corn varieties are classified by their maturity period, which refers to the number of days it takes from planting to harvesting. Choose a variety that matures in accordance with your local growing season.
- Height: Corn plants can range in height from 3 to 12 feet. Select a variety that suits the available space in your garden.
- Sweetness: Corn is classified as either sweet corn or field corn. Sweet corn is the type we typically eat, while field corn is used for animal feed.
Preparing the Soil
Corn requires well-drained, fertile soil with a pH between 6.0 and 6.8. Before planting, amend the soil with organic matter such as compost or manure to improve its structure and fertility.
Planting Corn
- Timing: Plant corn after the last spring frost, when the soil temperature has reached at least 60°F (16°C).
- Spacing: Plant corn kernels 6-8 inches apart in rows spaced 30-36 inches apart.
- Depth: Plant kernels 1-2 inches deep in the soil.
Watering Corn
Corn is a thirsty plant that requires regular watering, especially during hot, dry weather. Water deeply and evenly, allowing the soil to dry out slightly between waterings.
Fertilizing Corn
Fertilize corn every 3-4 weeks with a balanced fertilizer. Use a fertilizer with a high nitrogen content during the early stages of growth, and switch to a fertilizer with a higher phosphorus content as the plants mature.
Controlling Pests and Diseases
Corn is susceptible to a variety of pests and diseases. Common pests include corn earworms, aphids, and spider mites. Diseases that can affect corn include corn smut, stalk rot, and ear rot. Practice good garden hygiene and use organic pest and disease control methods whenever possible.
Harvesting Corn
Corn is ready to harvest when the kernels are plump and milky. The husks should be dry and turning brown. To harvest corn, twist the ear and pull it down.
Storing Corn
Fresh corn can be stored in the refrigerator for up to a week. For longer storage, freeze corn kernels or blanch and can them.
Troubleshooting Common Problems
- Poor germination: Ensure that the soil is warm enough and the seeds are planted at the correct depth.
- Stunted growth: Corn may be stunted if the soil is too poor or if there is insufficient watering.
- Yellowing leaves: Yellowing leaves can indicate nitrogen deficiency or disease. Fertilize with a balanced fertilizer or treat the disease.
- Earworms: Control earworms by using organic insecticides or planting companion plants that repel pests.
