When to Plant Chard in Bradford County, FL

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.

Bradford County, Florida is in USDA Zone 9a. The average last spring frost is March 1 and the first fall frost is November 28, giving you a growing season of approximately 272 days.

At an elevation of 297 feet, Bradford County receives approximately 51.9 inches of rainfall annually with predominantly sand soil. Summer highs average 98ยฐF, so Chard may need afternoon shade and extra watering during peak heat.

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 6,392 GDD Excellent fit
