INTRODUCING CORN SEEDS
Corn, also known as maize, has been cultivated for thousands of years. Its origins trace back to ancient Mesoamerica. It's not only a dietary staple for many cultures; it also plays a key role in a sustainable garden ecosystem. Growing corn in a diverse garden setting can support a variety of wildlife and work well as a companion plant, especially to squash and beans in a traditional “Three Sisters” planting. Corn is adaptable to a range of climates across the USA. It’s suitable for growing in USDA hardiness zones 3 to 11. Corn’s planting times vary depending on local weather conditions and variety.
HOW TO PLANT CORN SEEDS
Knowing when to plant corn seeds is the first step to a bountiful harvest at the end of the season. After the danger of frost has passed and the soil is warm, you can directly sow outdoors. Corn does not transplant well and does best when planted in its final growing spot. Because corn seeds are quite large, they should be sown deeper than other seeds, at about 1 inch deep. Your corn plants should be spaced approximately 9 to 12 inches apart if grown in rows, so plant wisely. Corn is wind-pollinated, so to achieve effective pollination, plant in blocks of at least four rows. Keep the soil moist, and water regularly, especially during silk and tassel development, to encourage good kernel formation.
MAINTAINING CORN PLANTS
The most important maintenance of corn plants is regular watering, especially during dry periods. This supports their rapid growth and proper kernel development. Corn is a heavy feeder, and nitrogen is essential for lush, full growth. This is why mulching, companion planting with legumes, organic nitrogen boosters, and regular crop rotation are so beneficial in small-scale garden scenarios. Keep an eye out for pests and diseases, and address any issues promptly.
The timing of harvesting depends on the type of corn grown. Sweet corn is eaten as a vegetable so it is harvested earliest when the kernels are at the “milk stage” - that is about 70-80% water. Harvest when the silks turn brown, but the husks are still green in mid to late summer. Dent corn or field corn has a lower moisture content – around 15-25% – and is harvested in late summer or fall. The kernels will be hard. Popcorn must have an even lower moisture content (15-20%) so that the kernels pop when heated. This is also in late summer to fall.
Corn has been around to see many different cultures come and go. It has been praised in the Americas and all parts of the world as nature’s gold. Now, gardeners can experience the satisfaction of growing this beauty. Enjoy sweet corn eaten fresh off the cob, dent corn as corn meal or masa, and popcorn popped for a movie night snack. It is also beautiful when used as part of a decorative autumn arrangement.
