Swiss chard is a colorful, heat-tolerant green with large crinkled leaves and vibrant stalks in red, yellow, and white. Both the leaves and stems are edible and nutritious.

Midland County, Texas is in USDA Zone 7b. The average last spring frost is March 20 and the first fall frost is November 14, giving you a growing season of approximately 239 days.

At an elevation of 1,546 feet, Midland County receives approximately 52.8 inches of rainfall annually with predominantly sandy loam soil.

Chard 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.

Chard needs ~1,292 GDD — county provides 5,616 GDD Excellent fit
