When to Plant Lentils in Culberson County, TX

Lentils are an ancient pulse crop producing small, lens-shaped seeds packed with protein and iron. They grow on short, bushy plants and are surprisingly easy to cultivate.

Culberson County, Texas is in USDA Zone 7b. The average last spring frost is March 29 and the first fall frost is November 11, giving you a growing season of approximately 227 days.

At an elevation of 2,716 feet, Culberson County receives approximately 50.5 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96ยฐF, so Lentils may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Lentils will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Lentils root diseases.
