🥬 Swiss Chard 'Rainbow' Mix – Seeding Guide

📅 When to Sow

Outdoors (direct sow – recommended):

• Early spring, as soon as soil can be worked (2–4 weeks before last frost)

• Again in late summer for fall harvest
  (Tolerates light frost; can overwinter in mild climates)

Indoors:

• Start 3–4 weeks before last frost, then transplant after hardening off

🌱 How to Sow

Seed Prep (Optional but helpful):

• Soak seeds in warm water for 4–8 hours to speed germination

Sowing Depth:

• ½ inch (1.25 cm) deep

Spacing:

• Direct sow: 2–4 inches apart

• Rows: 12–18 inches apart

• Thin to 8–12 inches apart once seedlings are a few inches tall
  (Each “seed” is actually a cluster and may produce 2–3 seedlings)

🌡️ Germination

• Temperature: 50–85°F (10–29°C)

• Time: 7–14 days

🌞 Growing Conditions

• Sun: Full sun to part shade

• Soil: Loose, fertile, well-drained; pH 6.0–7.0

• Water: Keep evenly moist but not soggy

🌿 Harvest

• Begin harvesting baby leaves at 4–6 inches tall (25–30 days)

• Full maturity in 50–60 days

• Cut outer leaves 1–2 inches above the base; new leaves will regrow

🌈 Tips

• Great in raised beds, garden rows, or containers

• Heat- and cold-tolerant

• Keep picking to prevent bolting in hot weather

• Mulch to retain moisture and keep roots cool
