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.
PLANTING
Corn is picky about its soil. Work in aged manure or compost the fall before planting and let over winter in the soil.
Starting seeds indoors is not recommended.
Plant seeds outdoors two weeks after the last spring frost date.
Make sure soil temperature is above 60 degrees for successful germination. (Up to 65 for super sweet varieties.) In colder zones, the ground can be warmed by a black plastic cover if necessary. Plant seeds through holes.
Plant seeds 1 inch deep and 4 to 6 inches apart. Rows 30 to 36 inches apart.
For sufficient pollination, plan your plot right. Don’t plant two long rows, rather, plant corn blocks of at least four rows.
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.
Water well at planting time.
