    March
    1. Buy

    Buy corn seed when available via mail-order or at the nursery.
    2. Sow Seeds

    Sow seeds indoors in a well-draining seed-starting mix. When the seedlings come up, place them in a bright window.
    April
    1. Buy

    Buy corn seeds when available via mail-order or at the nursery. Plants are occasionally available at the nursery.
    2. Plant

    If you find plants, place them 2 to 3 feet apart in blocks of four side-by-side rows, as corn requires adequate cross-pollination to produce full-sized cobs.
    3. Sow Seeds

    In a full-sun, well-draining location with rich soil, sow seed 2 to 3 feet apart in blocks of four side-by-side rows. Corn requires cross-pollination to produce full-sized cobs. For a continuous harvest, sow seed every 2 to 3 weeks.
    4. Fertilize

    Feed with a high-nitrogen fertilizer when the stalks reach 12- to 15-feet-tall; repeat when stalks reach 2- to 2 1/2-feet tall.
    5. Water

    Keep plants moist but not soggy. Droughted plants will stop producing.
    6. Mulch

    Apply a 2- to 3-inch layer of shredded bark to help maintain consistently moist soil.
    7. Special requirements

    Avoid planting popcorn near sweet corn, as they will cross-pollinate.

    3. Sow Seeds

    In a full-sun, well-draining location with rich soil, sow seed 2 to 3 feet apart in blocks of four side-by-side rows. Corn requires cross-pollination to produce full-sized cobs. For a continuous harvest, sow seed every 2 to 3 weeks.

    5. Water

    Keep plants moist but not soggy. Droughted plants will stop producing.
    6. Mulch

    Maintain a 2- to 3-inch layer of shredded bark to help maintain consistently moist soil.
    7. Pest/Disease Inspection

    Check for signs of corn earworms, which come from moths. The larvae (caterpillars) feed on the corn silks and eventually make their way into the tip of the corn where they continue feeding.
    8. Treat for Pest/Disease

    Prevent corn earworm infestations by putting two drops of mineral oil inside the tips of the ears 3 to 7 days after silks appear. Also kill off the worms (caterpillars) by applying the biological control Bacillus thuringiensis to the plant.
    9. Harvest

    Harvest when the ears are plump and the silks have withered and started to brown. Test for harvest readiness by pulling back the silks to expose the tip of the corn and pricking a kernel with your fingernail. The liquid that releases should be milky in color. Watery liquid means the corn is still immature, and very little or thick liquid means that the corn is past its prime. For the sweetest flavor, eat soon after harvest.
    10. Special requirements

    Avoid planting popcorn near sweet corn, as they will cross-pollinate.
