Planting Instructions

Seed Preparation

• No pre-soaking required, but starting indoors ensures better control over germination conditions.

Sowing Guidelines

Indoor Sowing (Recommended for Early Start):

• Start seeds indoors 6-8 weeks before the last frost.
• Sow seeds ¼ inch deep in seed-starting mix.
• Maintain soil temperature at 65-75°F (18-24°C) for best germination.
• Provide 12-14 hours of light daily using grow lights or a sunny windowsill.

Outdoor Sowing:

• Direct sow in late summer or early fall for overwintering in mild climates.
• Plant seeds ¼ inch deep, spaced 12 inches apart in rows 18-24 inches apart.

Germination

• Seeds typically sprout within 7-14 days under ideal conditions.
• Keep soil consistently moist but not waterlogged.

Transplanting

• Transplant seedlings outdoors when they are 4-6 inches tall and nighttime temperatures remain above 45°F (7°C).
• Harden off seedlings by gradually exposing them to outdoor conditions for 7-10 days.

Spacing & Growing Conditions

• Within Rows: 12-18 inches apart
• Between Rows: 18-24 inches apart
• Depth: Plant at the same depth as they were in containers.

Care & Maintenance

• Watering: Keep soil evenly moist, providing 1-1.5 inches of water per week. Avoid overhead watering to prevent disease.
• Fertilization: Apply a balanced fertilizer at planting and side-dress with compost or organic fertilizer mid-season.
• Mulching: Use mulch to retain moisture, regulate soil temperature, and suppress weeds.
• Support: Not required, but row covers can protect from pests and cold snaps.

Harvesting

• Harvest white sprouting florets when they reach 4-6 inches long, before flowers open.
• Cut main shoots first to encourage side shoot production for extended harvesting.
• Store in a cool, dark place or refrigerate for extended freshness.

Pest & Disease Control

• Common Pests: Cabbage worms, aphids, flea beetles. Use row covers, neem oil, or companion planting (e.g., marigolds) to deter pests.
• Common Diseases: Clubroot, downy mildew, black rot. Rotate crops annually and ensure good air circulation.
