Corn
Zea mays subsp. mays
Sweet corn is an annual with yellow, white, and bi-colored ears. A long, frost-free growing season is necessary after planting. Sweet corn is wind-pollinated, so it should be planted in blocks, rather than in single rows. Early, mid, and late-season varieties extend the harvest. If you miss the optimal harvest time, corn will go downhill fast as sugars convert to starch.

Growing from Seed
Plant seeds 1 inch deep and 4 to 6 inches apart. Space rows 30 to 36 inches apart.
Planting Considerations
Corn is picky about its soil. Work in compost the fall before planting and let over winter in the soil. Starting seeds indoors is not recommended.
Feeding
You may choose to fertilize at planting time, corn is meant to grow rapidly. If you are confident that the soil is adequate, this can be skipped.
Harvesting
Harvest when tassels begin to turn brown and cobs start to swell. Kernels should be full and milky. Pull ears downward and twist to take off stalk.
Storage
Sweet corn varieties lose their sweetness soon after harvesting. Prepare for eating or preserving immediately after picking. Sweet corn freezes well, especially if removed from ears before freezing. If you do store your corn in the fridge, leave them in their husks!
