Best Time To Plant Sweet Corn In Missouri
Sweet corn is a beloved Midwest staple, and planting it at the right time is crucial for a successful harvest. In Missouri, the best time to plant sweet corn depends on several factors such as weather patterns, soil conditions, and frost dates. In this article, we will discuss the ideal planting times for sweet corn in Missouri and provide tips on how to ensure a bountiful harvest.
Types of Sweet Corn
Before diving into planting times, it’s important to understand the different types of sweet corn. There are three main varieties: standard sweet corn, supersweet corn, and early-season sweet corn. Standard sweet corn has a higher sugar content and is ready to harvest within 20-25 days after the silks emerge. Supersweet corn has a higher sugar content than standard sweet corn, but takes longer to mature (70-85 days). Early-season sweet corn matures in 60-70 days but has a lower sugar content than the other two varieties.
Planting Times
In Missouri, the best time to plant sweet corn is between mid-May and mid-June. This time period coincides with the last frost date for most areas in the state. Before planting, ensure that the soil temperature is at least 60°F, as sweet corn prefers warm soil. Planting too early can result in stunted growth, while planting too late can result in a shortened growing season and smaller ears of corn.
When planting sweet corn in Missouri, it’s important to consider the weather patterns. Missouri is known for its unpredictable weather, and planting during periods of heavy rain can result in poor seed germination. It’s best to wait until the soil has dried out enough to work before planting.
Preparing the Soil
Preparation of the soil is critical in ensuring a successful sweet corn harvest. Before planting, plow or till the soil to a depth of at least 8 inches. Add compost or well-rotted manure to the soil to improve drainage and fertility. Sweet corn prefers a soil pH between 5.8 and 6.5, so it’s important to test the soil and adjust the pH if necessary.
Planting Tips
When planting sweet corn, it’s best to plant in blocks rather than rows. The reason for this is that sweet corn is wind-pollinated, and planting in blocks ensures that the pollen will be spread more efficiently. Plant seeds 1-2 inches deep and 6-8 inches apart, and water thoroughly after planting.
As the sweet corn begins to grow, it’s important to weed the area regularly. Weeds can compete with the sweet corn for nutrients and water, and can hinder growth. Consider using a mulch around the plants to help retain moisture and suppress weed growth.
Harvesting Sweet Corn
Sweet corn is ready to harvest when the silks turn brown and dry, and the kernels are plump and full. To check if the sweet corn is ready, gently peel back the husk and press a kernel with your fingernail. If a milky liquid spurts out, the corn is ready to harvest. Avoid over-ripening the sweet corn, as it can result in a starchy flavor.
Conclusion
Planting sweet corn in Missouri requires careful timing, preparation, and planting techniques. By following the tips outlined in this article, you can ensure a bountiful harvest of delicious sweet corn. Remember to plant during the optimal time, prepare the soil properly, and monitor the sweet corn as it grows. Happy planting!
