5. To add a touch of fragrance to your corn patch, consider planting some herbs like cilantro or dill. These herbs attract beneficial insects, such as pollinators and pest predators, which can help ensure a healthy corn harvest.
Popularity And Varieties Of Sweet Corn
Sweet corn is an incredibly popular vegetable, with New England allocating half of its vegetable acreage specifically for sweet corn production. This shows just how revered this crop is in the region. One interesting fact about sweet corn is that its ears can have different colored kernels. These colors can range from all yellow, all white, or even a combination of both, known as bicolor. In New England, the bicolor varieties have gained the most popularity among consumers, highlighting their preference for this unique combination.
Additionally, sweet corn differs from field corn due to a genetic mutation at the sugary locus (su). This mutation results in kernels that are notably sweeter than those found in field corn. It’s no wonder why sweet corn is often a favorite at summer barbecues and family meals. Moreover, sweet corn varieties vary in terms of their starchiness after harvest. Traditional sweet corn varieties usually become starchy relatively quickly, while sugary-enhanced varieties have the ability to accumulate more sugar. Finally, super-sweet varieties are considered the sweetest of them all, making them a sought-after choice for corn lovers.
Growing Requirements For Sweet Corn
To achieve successful growth of sweet corn, it is essential to provide the right growing conditions. Here are some key factors to consider:
-
Sun Exposure: Sweet corn requires full sun exposure for optimal growth and productivity.
-
Soil Temperature: The soil temperature should be at least 50°F for germination to occur.
-
Soil Type: Sweet corn thrives in well-drained and fertile soil with a pH level ranging from 6.0 to 6.8.
Ensuring your soil meets these conditions will significantly contribute to the overall success of your corn crop.
Water is another vital element for sweet corn. Here’s what you need to know:
-
Irrigation: Adequate irrigation is crucial, with the most critical period being about two weeks before silks form. During this time, the plants need ample water to ensure proper development and the formation of healthy ears.
-
Feeding: Sweet corn is a heavy feeder, so it is recommended to conduct a soil test before planting to determine the need for lime and fertilizers.
-
Soil Preparation: Incorporating aged manure or compost in the fall prior to planting can provide essential nutrients and increase the water-holding capacity of the soil.
Remember: Providing the right growing conditions, including proper sun exposure, soil temperature, and irrigation, is key to successfully growing sweet corn.

Tips For A Continuous Supply Of Sweet Corn
For those aiming to have a continuous supply of sweet corn throughout the growing season, careful planning and planting techniques are essential. Planting a small amount of the same corn variety every 7 to 10 days can help stagger the maturity of the plants. Alternatively, simultaneous planting of different varieties can also achieve a similar result. By implementing these practices, you can ensure a steady supply of fresh sweet corn, extending the enjoyment of this delicious vegetable throughout the season.
Fertilization And Pest Management For Sweet Corn
Fertilizing sweet corn appropriately is crucial for obtaining a healthy and bountiful crop. Typically, corn needs around 25 lbs of 10-10-10 fertilizer per 1,000 square feet. However, alternative synthetic or organic fertilizers can also be used. Sidedressing with nitrogen fertilizer, at a rate of approximately 2.5 lbs of a 10% nitrogen product per 100 feet of row, can significantly benefit sweet corn when the plants reach a height of 15 to 18 inches.
To ensure successful pollination, which directly influences yield, it is recommended to plant several short rows of corn in a block formation. This increases the likelihood of the wind carrying pollen from the tassels to the silks, resulting in a better chance of pollination. Proper spacing is also key. Rows should be spaced between 2.5 to 3 feet apart, with individual plants spaced 8 to 10 inches apart. Following these guidelines will provide sufficient room for each plant to grow and maximize their potential.
Common Pests And Control Methods For Sweet Corn
Various pests pose a threat to sweet corn, and appropriate pest management techniques are necessary to protect the crop. Among these pests are the European Corn Borer and corn earworms, which can cause significant damage if left unchecked. Integrated pest management methods, such as trapping, can effectively control these pests and reduce their impact on sweet corn.
Smut, a fungal disease that occasionally affects sweet corn, is another concern for corn growers. Infected ears should be promptly detected and cut off, then carefully disposed of to prevent further spread. Additionally, birds and crows can pull up germinating corn, potentially causing significant damage. Employing polyester row covers as a protective measure can effectively deter these pests.
Furthermore, raccoons can pose a threat to ripening corn. To keep these critters at bay, installing electric fencing with two low electrified strands can effectively exclude them from the corn plantings. By implementing these pest management techniques, you can protect your sweet corn crop and ensure a successful harvest.

Frequently Asked Questions
What is the best thing to plant beside corn?
One excellent choice to plant beside corn is marigolds. Marigolds are known to attract beneficial insects such as ladybugs and hoverflies, which can help control pests that might harm the corn. Additionally, marigolds have a strong scent that can repel harmful nematodes and insects, providing natural pest control for the corn plants.
Another great option to consider is pole beans. These plants can serve as natural trellises for the corn, allowing the beans to climb up the corn stalks. This symbiotic relationship benefits both plants, as the beans provide nitrogen fixation to enrich the soil, while the corn provides support for the beans to grow upward. Together, corn and pole beans create a visually appealing and mutually beneficial garden combination.
What does corn grow best in?
Corn grows best in well drained and fertile soil with a pH level ranging from 6.0 to 6.8. However, the type of soil required for corn may vary depending on the planting time. For early corn, it thrives in light soil such as sand or loam as it warms up faster, facilitating seed germination. On the other hand, if planting corn later in the season, heavier soil like silt or clay is preferable. This helps to provide a more stable growing environment for the crop.
Can corn and zucchini be planted together?
Yes, corn and zucchini can be planted together as they are part of the three sister vegetables that thrive when planted together. The symbiotic relationship between these plants benefits each other’s growth. The corn provides a structure for the zucchini vines to climb, while the zucchini’s broad leaves help shade the soil, conserving moisture and reducing weed growth. Additionally, the zucchini discourages pests that may harm the corn, creating a natural pest control system. Thus, planting corn and zucchini together not only enhances their individual growth but also promotes a harmonious and beneficial ecosystem in the garden.
What corn is best for three sisters?
For the optimal three sisters gardening, it is recommended to use a corn variety that can withstand the weight of the beans without getting pulled down. Native American gardeners traditionally used corn varieties with shorter stalks or multiple stalks to ensure stability. While any sweet corn variety can be used, selecting a heartier corn variety that meets these criteria will enhance the success of the three sisters gardening technique.
