Aerospace Cauliflower Seed

Outdoor Sowing (Directly in the Garden)

• Timing: Sow cauliflower seeds outdoors in early spring, 4–6 weeks before the last frost date, or in late summer for a fall harvest. Cauliflower grows best in cool temperatures between 60–75°F (15–24°C).
• Location: Choose a sunny spot with fertile, well-draining soil. Cauliflower can tolerate partial shade, especially in warmer climates.
• Soil Preparation: Loosen the soil to a depth of 12 inches and incorporate compost or well-rotted manure to improve fertility and drainage. Cauliflower grows best in slightly acidic to neutral soil with a pH of 6.5–7.5.
• Planting Seeds:
  • Sow seeds 1/2 inch deep and 1–2 inches apart in rows.
  • Space rows 18–24 inches apart for proper airflow and ease of harvesting.
• Thinning: Thin seedlings to 18–24 inches apart once they are 3–4 inches tall to give plants room to grow.
• Watering: Keep the soil consistently moist but not waterlogged. Water deeply and regularly, especially during head formation.

Indoor Sowing (Starting Seeds Indoors)

• Timing: Start cauliflower seeds indoors 6–8 weeks before the last expected frost date for an earlier harvest.
• Containers: Use seed trays or small pots with good drainage, filled with a light, well-draining seed-starting mix.
• Planting:
  • Sow seeds 1/4–1/2 inch deep, placing 1–2 seeds per cell or pot.
  • Cover lightly with soil and water gently.
• Germination:
  • Maintain a temperature of 65–75°F (18–24°C) for optimal germination.
  • Expect seedlings to emerge within 7–10 days.
• Transplanting: Transplant seedlings outdoors when soil temperatures are consistently above 50°F (10°C) and plants have 4–6 true leaves. Space plants 18–24 inches apart in rows.

General Care Tips for Cauliflower

• Sunlight: Provide full sun for best growth. Cauliflower can tolerate partial shade, especially in warmer climates.
• Watering: Water consistently to keep the soil evenly moist but not soggy. Mulch around plants to retain moisture and suppress weeds.
• Fertilizing: Cauliflower is a heavy feeder. Enrich the soil with compost before planting and side-dress with a nitrogen-rich fertilizer every 3–4 weeks to encourage steady growth.
• Blanching: To maintain the white color of the cauliflower heads, tie the outer leaves over the developing head when it is about 2–3 inches in diameter. This will protect the head from sunlight and prevent yellowing.
• Weeding: Keep the area weed-free to reduce competition for nutrients and moisture. Be careful not to disturb cauliflower's shallow roots when weeding.
• Pest and Disease Control: Monitor for pests like cabbage worms, aphids, and flea beetles. Use row covers to protect young plants, and hand-pick pests or use organic pest control methods as needed. Ensure good airflow to prevent fungal diseases like powdery mildew.
• Harvesting: Harvest cauliflower when the heads are firm, compact, and about 6–8 inches in diameter. Cut the head from the base with a sharp knife, leaving some outer leaves attached to protect the head during storage.
• Storage: Store harvested cauliflower in a cool, humid place like a refrigerator or root cellar. Heads can last for up to 2–3 weeks if properly stored.
