Care Guide

light_mode

Light

Full sun preferred; 6–8 hours of direct sunlight daily. Tolerates partial shade but produces fewer, slower-growing leaves. Some afternoon shade in hot climates reduces bolting.

water_drop

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.

compost

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.

science

Fertiliser

Moderate to heavy feeder. Apply balanced fertilizer (10-10-10) every 4 weeks, or side-dress with compost. Nitrogen supports leaf growth; avoid excessive amounts that delay maturity.

thermometer

Temperature

Grows well in 50–75°F (10–24°C). Cold-hardy; tolerates light frosts and even light snow. Heat stress is minimal with adequate water; more cold-tolerant than spinach.

humidity_percentage

Humidity

Moderate to high humidity (50–70%) preferred. Good air circulation prevents fungal diseases. Water early in the day to allow foliage to dry.
