Fava beans are a cool-season legume with large, meaty beans inside thick pods. They fix nitrogen in the soil and are one of the oldest cultivated crops.
Roberts County, Texas is in USDA Zone 7a. The average last spring frost is April 17 and the first fall frost is October 24, giving you a growing season of approximately 190 days.
At an elevation of 1,068 feet, Roberts County receives approximately 51 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98°F, so Fava Beans may need afternoon shade and extra watering during peak heat.

Fava Beans 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" — every day above 50°F 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.
