Care and Maintenance

Swiss Chard requires regular watering and full to partial sun. Consistent moisture is especially important during the growing season when roots are establishing.

• Watering: Regular — water deeply at the base, not overhead, to prevent leaf disease
• Mulching: Apply 2-3 inches of straw or shredded leaves to conserve moisture and suppress weeds
• Feeding: Apply balanced organic fertilizer or compost tea every 3-4 weeks during active growth
• Watch for deficiencies: Yellow leaves = nitrogen, purple stems = phosphorus, brown leaf edges = potassium

Pro Tips

Cut outer leaves first and the center will keep producing for months. Chard tolerates both heat and light frost, making it one of the most season-flexible greens.
