Direct-sow Corn when the soil is reliably warm, above 60°F, well after the last spring frost date. Prepare a well-draining area with rich soil in full sunlight. Amend the soil as necessary with organic fertilizer, compost and/or well-rotted manure. Corn is pollinated by the wind, so grow a minimum of 4 rows, even if they are short rows, to ensure good pollination. If the weather gets wet and cold, you might want to re-seed just to be safe since Corn has a long maturation cycle. After thinning to 10" to 12" between the plants, water regularly and mulch with hay or straw to deter weeds and retain ground moisture. Corn is particularly hungry for nitrogen: feed regularly as needed.Harvest when the silk begins to turn brown and a kernel, pinched with your fingernail, releases its sweet,milky liquid.Harvest shortly before cooking by holding the stalk and twisting the ears off at their bases.
Note: Try growing Corn in the ancient “Three Sisters”method: in hills spaced 5' apart, sow 3 seeds in the center of each hill. Sow 6 Pole Bean seeds adjacent to the Corn seeds and then sow Pumpkin or Winter Squash seed in the valleys between the hills. The Beans will scramble up the Corn and the Squash will ramble on the ground, creating a living mulch.
Winning the Corn Olympics
Corn is easily grown by sowing it directly into the ground. This is the simplest, most logical way to grow Corn. But if you're in a race to be the first in your neighborhood with Sweet Corn, try this trick. Since Corn needs a much warmer temperature to germinate than it does to grow, start the seeds indoors and then transplant them into the garden the minute you see the Sprouts emerge. This must be done immediately, since the little seedlings grow quickly and can easily become potbound.
In July or August, after the Corn crop is well on its way toward harvest time, set out some Broccoli transplants in between the rows. The shade cast by the cornstalks will help keep the Broccoli from going to seed in hot weather. After the Corn has been picked, cut the stalks down and turn the space over to the Broccoli, which will bear a nice fall crop. A Bean crop would work also, but choose a bush variety. Vining Beans will climb all over the Corn plants and fell them like timber.
Cooking Tip: Uncanny Creamed Corn
Why do most people think creamed Corn always comes in a can? You’ll never touch that sweet, gummy stuff again after you’ve tried creaming fresh Corn. Just cut the kernels off the cob and simmer them in cream until the kernels are cooked and the cream has reduced and thickened. No sugar needed!
