When to Plant Lentils in Matagorda 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.

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 95ยฐF, 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.

Lentils 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.

Lentils needs ~2,019 GDD — county provides 6,183 GDD Excellent fit
