From picking the right seeds to planting in blocks (not rows!) and knowing exactly when to harvest, this guide will help you grow corn that’s golden in every way. Let’s get popping!

About Sweet Corn

Sweet corn is a tender, warm-season annual crop that produces ears of yellow, white, or bi-colored kernels. Native to the Americas, sweet corn has been cultivated for thousands of years; it’s famous as one of the Three Sisters—corn, beans, and squash—grown by Native Americans.

A long, frost-free growing season (60 to 100 frost-free days) is necessary to grow and harvest corn. Don’t be tempted to sow too early, though. Mid to late spring is just fine once any chance of frosts is long gone.

And corn is a grass! A member of the Poaceae family, corn relies on wind, not bees or insects, to pollinate its flowers. This is why we plant corn in blocks of short rows instead of long, single rows.

Types of Sweet Corn

For a continuous supply of sweet corn, plant early, mid-season, and late varieties or plant every 2 or 3 weeks.

Have you ever had the intensely disappointing experience of tucking into a juicy-looking sweet corn cob only to find it tastes bland? This is the number one reason why paying a little bit more for your seeds pays big dividends. Hybrid or F1 varieties of sweet corn may cost a bit more, but they’re worth every penny, yielding cobs with a superior flavor, especially if you pick one of the supersweet types. Varieties bred for sweetness hold their taste for longer, too, but the sooner you cook them after picking, the better.
