When to Plant Corn in Matagorda County, TX
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.
Matagorda County, Texas is in USDA Zone 9a. The average last spring frost is February 19 and the first fall frost is December 6, giving you a growing season of approximately 290 days.
At an elevation of 161 feet, Matagorda County receives approximately 57.1 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95°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.
