Choosing the Right Corn Variety
The first step in learning how to plant corn plants is selecting the right type. Different corn varieties are bred for specific traits, such as sweetness, disease resistance, and maturity time. Consider your local climate and growing season when making your selection. This will greatly impact your success and the amount of corn you harvest.
Sweet Corn Types
Sweet corn is the most popular type for home gardens. It’s known for its high sugar content and delicious flavor. There are three main types of sweet corn:
- Sugary (su) corn: The standard sweet corn, offering good flavor but with sweetness that declines quickly after harvest.
- Sugary Enhanced (se) corn: These varieties have higher sugar content and retain their sweetness longer than su corn. They also have a more tender kernel texture.
- Super Sweet (sh2) corn: These are the sweetest varieties, with very high sugar content. They require careful handling and isolation from other corn types to prevent cross-pollination.
Other Corn Types
Besides sweet corn, other types are also available:
- Popcorn: Grown specifically for popping, popcorn varieties have hard kernels and a distinct flavor.
- Flint corn: Also known as Indian corn, flint corn is used for cornmeal and decoration.
- Dent corn: Used primarily for livestock feed and cornstarch production.
Popular Corn Varieties
Here are some popular and reliable sweet corn varieties:
| Variety | Type | Days to Maturity | Key Features |
|---|---|---|---|
| Silver Queen | su | 75-85 | Classic white corn, good flavor |
| Golden Bantam | su | 70-80 | Yellow corn, heirloom variety |
| Early Sunglow | su | 60-70 | Early maturing, yellow corn |
| Honey Select | se | 75-80 | Yellow corn, excellent sweetness |
| Xtra-Sweet | sh2 | 75-85 | Very sweet, good for freezing |
Consider the maturity time of each variety and choose one that fits your growing season. Early-maturing varieties are ideal for shorter growing seasons. Consider disease resistance, especially in areas prone to corn diseases.
Preparing the Soil for Corn Plants
Successful corn cultivation hinges on healthy soil. Corn plants are heavy feeders and require nutrient-rich, well-draining soil. Proper soil preparation is a critical step in knowing how to plant corn plants.
Soil Testing
Before planting, test your soil to determine its pH and nutrient levels. This will help you identify any deficiencies and adjust your soil accordingly. Soil testing kits are readily available at garden centers and online. The ideal pH for corn is between 6.0 and 6.8. If your soil pH is too low (acidic), add lime to raise it. If it’s too high (alkaline), add sulfur or other soil amendments.
Soil Amendments
Improve your soil’s fertility by adding organic matter. This can include compost, well-rotted manure, or cover crops. Organic matter improves soil structure, drainage, and water retention. It also provides essential nutrients for the corn plants. Work the amendments into the soil to a depth of at least 6-8 inches.
Tilling and Cultivating
Till or cultivate the soil to loosen it and remove any weeds or debris. This process also helps to incorporate the soil amendments evenly. Tilling ensures good aeration and allows the corn roots to penetrate easily. If you have a large area, use a rototiller. For smaller gardens, a garden fork or shovel will suffice. Rake the soil surface to create a smooth seedbed.
Fertilizing
Corn is a heavy feeder, especially of nitrogen. Apply a balanced fertilizer before planting, following the package instructions. Consider using a fertilizer specifically formulated for corn or vegetables. Side-dress your corn plants with additional fertilizer during the growing season, particularly when the plants are about knee-high and again when tassels appear. This will provide the plants with the nutrients they need for optimal growth and yield.
Planting Corn Seeds
Once your soil is prepared, it’s time to plant the corn seeds. Proper planting techniques will contribute significantly to your harvest success. Knowing how to plant corn plants correctly is crucial.
Timing
Plant corn when the soil temperature reaches at least 50°F (10°C). The optimal soil temperature for germination is between 60°F and 95°F (16°C and 35°C). Check your local frost dates to determine the best planting time in your area. You can stagger planting every couple of weeks to extend your harvest season.

Spacing and Depth
Plant corn seeds about 1-2 inches deep. The exact depth depends on your soil type; plant deeper in sandy soils and shallower in clay soils. Space corn plants about 6-12 inches apart within rows and space the rows 2.5-3 feet apart. This spacing allows for adequate air circulation and sunlight penetration, which helps prevent diseases. Consider planting in blocks rather than single rows to improve pollination.
Planting Methods
There are two main planting methods:
- Direct Seeding: This is the most common method for home gardeners. Simply sow the seeds directly into the prepared soil.
- Starting Indoors: You can start corn seeds indoors a few weeks before the last frost. Transplant the seedlings into the garden after the danger of frost has passed. This method can give you an earlier start to your harvest.
Watering After Planting
Water the newly planted seeds thoroughly after planting. Keep the soil consistently moist until the seedlings emerge. Avoid overwatering, which can lead to seed rot. A gentle watering method is ideal to avoid disturbing the seeds.
Protecting Seeds
Consider using a seed treatment to protect your seeds from pests and diseases, especially if you are in an area with known problems. Seed treatments can help improve germination rates and protect young seedlings. You can purchase corn seeds that are already treated or apply your own seed treatment.
Caring for Your Corn Plants
Once your corn plants are in the ground, consistent care is essential for a successful harvest. This includes watering, weeding, fertilizing, and pest and disease control. Knowing how to plant corn plants is only half the battle; proper care is the other half.
Watering
Corn requires consistent watering, especially during dry spells. Water deeply and regularly, providing about 1 inch of water per week, including rainfall. Water at the base of the plants to avoid wetting the foliage, which can increase the risk of fungal diseases. Mulch around the plants to help retain moisture in the soil.
Weeding
Keep the area around your corn plants weed-free. Weeds compete with corn for water, nutrients, and sunlight. Hand-pull weeds or use a hoe to cultivate shallowly around the plants. Be careful not to damage the corn roots when weeding. Mulching also helps suppress weed growth.
Fertilizing (ongoing)
Side-dress your corn plants with fertilizer during the growing season. Apply fertilizer when the plants are about knee-high and again when tassels appear. Follow the package instructions for the recommended application rate. Avoid getting fertilizer on the leaves, as it can cause burning. Water the plants after fertilizing to help the nutrients reach the roots.
Thinning
If you planted multiple seeds per hole, thin the seedlings to the recommended spacing. Thin the plants when they are a few inches tall, leaving the strongest seedlings. Remove any weak or damaged plants.
Pollination
Corn is wind-pollinated, so it’s important to plant corn in blocks rather than single rows. This helps ensure that the pollen from the tassels (the male flowers) reaches the silks (the female flowers) on the ears. You can also assist pollination by gently shaking the tassels to release pollen.
Pest Control
Corn plants are susceptible to various pests, including:
- Corn earworms: These pests feed on the developing kernels. Control them by applying insecticidal oil or Bt (Bacillus thuringiensis) to the silks when they appear.
- Corn borers: These pests bore into the stalks and ears. Use Bt or other insecticides to control them.
- Aphids: These small insects suck sap from the plants. Control them with insecticidal soap or by introducing beneficial insects, such as ladybugs.
Inspect your corn plants regularly for signs of pests. Early detection is key to preventing major infestations. Use organic pest control methods whenever possible.
Disease Control
Corn plants can also be affected by various diseases, including:
- Corn smut: This fungal disease causes large, gray galls on the ears and stalks. Remove and destroy infected plants to prevent the spread of the disease.
- Stewart’s wilt: This bacterial disease is spread by flea beetles. Control flea beetles to prevent the disease.
- Rust: This fungal disease causes reddish-brown pustules on the leaves. Use a fungicide to control rust.
Choose disease-resistant varieties whenever possible. Provide good air circulation by spacing plants appropriately. Practice crop rotation to reduce the risk of soilborne diseases. Remove and destroy any diseased plants. (See Also: How Do I Know If a Plant Is Dead? Signs & What to Do)
Harvesting Your Corn
Harvesting corn at the right time is crucial for the best flavor and texture. Timing your harvest correctly is essential for knowing how to plant corn plants successfully.
Signs of Ripeness
The following signs indicate that your corn is ready to harvest:
- Silks: The silks on the ears will turn brown and dry.
- Kernels: The kernels will be plump and full.
- Ear Feel: The ears will feel firm when squeezed.
You can also pierce a kernel with your fingernail. If a milky liquid comes out, the corn is ready to harvest. If the liquid is clear, the corn is not yet ripe. If the liquid is thick and pasty, the corn is overripe.
Harvesting Technique
Grasp the ear firmly and twist it downward to detach it from the stalk. You can also use a sharp knife or clippers to cut the ear from the stalk. Harvest corn in the morning when the ears are cool and the sugar content is at its peak. This helps preserve the corn’s sweetness.
Storage
Freshly harvested corn is best eaten immediately. However, you can store it for a short time. Store unhusked ears in the refrigerator for up to a week. For longer storage, husk the ears and freeze the kernels. You can also can or dry corn for later use.
Troubleshooting Common Problems
Even with the best care, you may encounter some problems while growing corn. Understanding these potential issues and how to address them is important when learning how to plant corn plants.
Poor Germination
If your corn seeds don’t germinate, the following may be the cause:

- Poor seed quality: Use fresh, high-quality seeds.
- Too much or too little water: Keep the soil consistently moist but not waterlogged.
- Pests or diseases: Seed treatments can help protect seeds from pests and diseases.
Yellowing Leaves
Yellowing leaves can indicate several problems:
- Nutrient deficiency: Corn is a heavy feeder, so make sure you are fertilizing regularly. Nitrogen deficiency is a common cause of yellowing.
- Water stress: Water your corn plants regularly, especially during dry spells.
- Pests or diseases: Inspect your plants for pests and diseases.
Poor Ear Development
Poor ear development can be caused by:
- Poor pollination: Plant corn in blocks to ensure good pollination.
- Nutrient deficiency: Make sure you are fertilizing regularly.
- Pests or diseases: Inspect your plants for pests and diseases.
Stalk Damage
Stalk damage can be caused by:
- Wind: Provide windbreaks if necessary.
- Pests: Control pests that bore into the stalks.
