Corn

TL;DR: Corn is a heat-loving, heavy-feeding crop that must be planted in blocks (not rows) for proper wind pollination. Direct-sow in full sun once soil hits 60°F, 8-12 inches apart in compost-rich soil. Keep soil consistently moist and side-dress with nitrogen fertilizer when plants are knee-high. Harvest when silks turn brown and kernels pass the "milk test." It's a good source of fiber, B vitamins, magnesium, and vision-supporting lutein and zeaxanthin.

Corn is a quintessential symbol of the summer garden, standing tall and proud with its lush green stalks and golden tassels. Known scientifically as Zea mays, this fast-growing cereal grain is unique because it relies on the wind for pollination rather than insects. Whether you are growing sweet corn for backyard barbecues or flint corn for grinding into flour, there is something incredibly satisfying about the rustle of corn leaves in a warm breeze. It is a heavy-feeding crop that requires space and sun, but the reward of biting into a kernel that was attached to the stalk just minutes prior is incomparable to anything bought at a store. Because corn is wind-pollinated, planting it requires a specific strategy: instead of one long row, you should plant it in "blocks" of at least four short rows. This ensuring that the pollen from the tassels at the top can easily fall onto the silks below. As a true heat-lover, corn should be direct-sown only after the soil has reached at least 60°F ( 15°C )—or even 70°F ( 21°C ) for super-sweet varieties. Sow the seeds about an inch deep and 8 to 12 inches apart in rich, fertile soil. Corn is "hungry" for nitrogen, so it’s a great idea to mix in plenty of compost or aged manure before you begin. Maintaining your corn patch is all about water and nutrition. Corn has a relatively shallow root system, so it can be sensitive to drought, particularly when the ears are developing. Keeping the soil consistently moist is key to ensuring the kernels fill out completely. Since corn is such a heavy feeder, "side-dressing" the plants with a nitrogen-rich fertilizer when they are about knee-high will give them the boost they need to reach their full height. Keep the area around the base of the stalks clear of weeds, but hoe carefully to avoid damaging those shallow roots. The moment of harvest is a brief but exciting window. You’ll know your corn is ready when the silks have turned brown and dry, and the ears feel firm and plump. A classic trick is the "milk test": puncture a kernel with your fingernail; if a milky liquid pops out, it’s at its peak sweetness. To harvest, simply grab the ear, snap it downward, and twist. Aside from being a fun crop to grow, corn provides a healthy dose of fiber for digestion, along with B vitamins and essential minerals like magnesium. It also contains lutein and zeaxanthin, which are fantastic for maintaining healthy vision.
