OVERVIEW:
Corn, like sunflowers, make a great backdrop to any garden. This popular plant has probably inspired more home gardens than any other vegetable. Corn is a worthwhile vegetable for any garden, and fresh corn on the cob is delicious!
Plant corn in the northern part of your graden (or any location that does not block the sun for other plants) after all danger of frost is past in well-fertilized soil. Corn may need additional water to make quality ears during a dry summer. Very hot weather can also have a negative effect on pollination of corn. For a continuous crop, stagger plantings a few weeks apart or choose corn varieties with different maturities.
PROPAGATION / SOWING OF CORN:
Corn is wind pollinated, so it must be planted in a block of several rows for even pollination. Sow corn seed 3-4” apart and about ½-1” deep in rows 24-32” apart. Thin the corn seedlings to 10-12” as ears will be greatly reduced in size or not form at all on crowded plants. Ornamental corn must be isolated from sweet corn. Planting corn in cool soil will set back seedlings, especially if a frost is still possible. Best to plant corn when the soil has warmed to 70-75°F. Plant several different varieties of varying maturities to ensure a longer season of harvest.
COMPANION PLANTING OF CORN:
Bush bean, beet, cabbage, cantaloupe, cucumber, parsley, pea, early potato, pumpkin, squash.
CARE & GROWING OF CORN:
Full sun is required. Corn is a heavy feeder and requires fertile, well-drained soil with a pH of 6.0-6.5. Prepare the soil by working in well-rotted manure or other organic matter. A side dressing of nitrogen, applied when corn plants are about knee high, will give corn an added boost in growth. Try bloodmeal, partially rotted manure or a liquid fertilizer. Corn needs plenty of moisture. Hill soil around the base of the plant when they are 6” high. This will help to anchor the plants and keep the roots covered and cool. Use a mulch to keep down weeds and conserve moisture.
HARVESTING OF CORN:
Corn is ready when the ears are completely filled and a pierced kernel shows a milky white liquid. A good sign of corn cob readiness is when the silk turns brown and crisp.
