Sow and Plant :Wait until the soil is warm to sow sweet corn. Soak seeds in water overnight before planting them 1 inch deep and 6 inches apart. Thin to 12 inches apart when the plants are 6 inches tall.
Plant in blocks of at least 15 plants, all the same variety, to insure good wind pollination. Keep well watered in dry spells.

Spacing : Single Plants: 1′ 1″ (35cm) each way; Rows: 11″ (30cm) with 1′ 5″ (45cm) row gap

Feeding : Needs more nitrogen than other vegetables. Mix an organic fertilizer into the soil before planting, following label application rates. When tassels form, feed plants second time.

Harvesting :Sweet corn is ready when the ears feel firm and full when grasped, and a test kernel pierced with a fingernail released milky juice. Harvest in the morning, and promptly refrigerate ears to help them hold their delicate sugars.
