Corn

Corn is a warm-season grass grown for its sweet ears, which are best eaten soon after harvest. It is wind-pollinated and must be planted in blocks for good kernel fill.

Osceola County, Florida is in USDA Zone 10a. The average last spring frost is January 22 and the first fall frost is December 20, giving you a growing season of approximately 332 days.

At an elevation of 352 feet, Osceola County receives approximately 58.7 inches of rainfall annually with predominantly sand soil. Summer highs average 102°F, so Corn may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Corn will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Corn root diseases.
