About Swiss Chard
Swiss chard (Beta vulgaris) is a colorful leafy vegetable in the beet family, prized for its glossy leaves and vivid stems in white, red, yellow, and orange. More heat tolerant than spinach or lettuce, it grows well in NE Florida as both a cool-season and warm-season crop — plant from late summer through spring for best production. Starting at $3.50.

Care essentials
Light
Swiss chard grows best with at least 6 hours of full sun daily. In NE Florida, morning sun with some afternoon shade can help extend productivity through warm spring days.
Water
Keep soil evenly moist with consistent watering — about 1 inch per week. In Florida's sandy soil, water more frequently and mulch around plants to reduce moisture loss and keep roots cool.
Soil & Fertilizer
Grows well in NE Florida's sandy loam when amended with compost. Prefers slightly acidic to neutral soil (pH 6.0–7.0). Apply a balanced slow-release vegetable fertilizer at planting and side-dress with compost mid-season to sustain leaf production.
