water
Keep soil consistently moist, providing 1–1.5 inches of water per week. Water deeply at the base to encourage strong root development. Reduce frequency slightly in cool seasons but never allow soil to dry completely.
soil
Rich, well-draining soil with pH 6.0–7.5. Incorporate 2–3 inches of compost or aged manure before planting. Swiss chard appreciates fertile soil but adapts to moderate fertility.
