When to Plant Eggplant in Edwards County, TX

Eggplant is a heat-loving solanaceous crop that produces glossy fruits in purple, white, or striped varieties. It requires long, warm growing seasons for best production.

Edwards County, Texas is in USDA Zone 8a. The average last spring frost is April 2 and the first fall frost is November 8, giving you a growing season of approximately 220 days.

At an elevation of 4,265 feet, Edwards County receives approximately 61.8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 102ยฐF, so Eggplant may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Eggplant will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Eggplant root diseases.
