rowing Conditions

• Zones: Hardy in USDA zones 2–11
• Climate: Prefers cool temperatures; heat inhibits leaf coloration
• Best Season in Warm Zones: Grow during winter for an early spring crop

☀️ Sunlight & Soil

• Sunlight: Full sun for best color development
• Soil: Well-draining, fertile soil with a pH of 6.0–7.5
• Spacing: Space plants 12–18 inches apart to allow full head formation

🌿 Planting & Support

• Planting Time: Sow seeds in late summer or early fall; transplant seedlings after 4–6 weeks
• Support for Cutting Types:

  • These varieties grow tall and top-heavy, requiring netting support

  • Use sturdy wooden or metal stakes to secure the netting
  • Apply one layer of netting, and raise it gradually as plants grow
  • Netting helps maintain straight stems and prevents lodging

✂️ Leaf Stripping Technique

• Timing: Begin when plants reach ~1 foot in height
• Method: Grip the stem just below the head and slide your hand downward to remove lower leaves
• Frequency: Strip leaves multiple times during the season rather than all at harvest
• Benefits: Promotes healing, reduces disease risk, and improves final appearance

💧 Watering & Maintenance

• Watering: Keep soil consistently moist but avoid waterlogging
• Fertilization: Apply a balanced fertilizer during early growth; reduce nitrogen later to enhance color
• Pest Management: Watch for aphids, cabbage worms, and fungal issues; use organic controls as needed
