When to Plant Eggplant in Val Verde 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.

Val Verde County, Texas is in USDA Zone 8a. The average last spring frost is February 17 and the first fall frost is December 7, giving you a growing season of approximately 293 days.

At an elevation of 3,979 feet, Val Verde County receives approximately 53.1 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98ยฐF, so Eggplant may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Eggplant root diseases.

Eggplant Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" โ€” every day above 50ยฐF deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Eggplant needs ~1,762 GDD — county provides 6,909 GDD Excellent fit
