Growing Swiss Chard in Zone 7A

Swiss chard is one of the most productive and ornamental vegetables you can grow. Its colorful stems — red, yellow, orange, white — add beauty to the garden while delivering harvests for months.

Zone 7A enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Direct sow 4 weeks before last frost or start indoors 4 weeks ahead
• Harvest outer leaves when 8-12 inches tall, leaving the center to keep producing
• Tolerates light frost — fall sowings often outlast the first few freezes
• Cut-and-come-again harvesting extends production all season
• Bolt-resistant in summer heat compared to spinach; a great warm-weather substitute

Companion Planting

Good companions: beans, onions, brassicas, tomatoes

Avoid planting near: beets (same family — shares pests and diseases)

Harvest Timeline

50-60 days from seed; harvest outer leaves continuously
