Arugula is a fast-growing cool-season green with a peppery, nutty flavor. It is excellent in salads and can be harvested as baby greens or mature leaves.

Ward County, Texas is in USDA Zone 8a. The average last spring frost is March 25 and the first fall frost is November 10, giving you a growing season of approximately 230 days.

At an elevation of 2,652 feet, Ward County receives approximately 53.3 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98°F, so Arugula may need afternoon shade and extra watering during peak heat.

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

Arugula 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.

Arugula needs ~940 GDD — county provides 5,405 GDD Excellent fit
