Red Onion

100 Seeds

Red Onion is a cool-season crop that produces flavorful, purple-red bulbs. It grows best during the mild months in the Gulf region and should be planted from early autumn through winter.

🌱 Best Growing Season in the Gulf

• Sow seeds: September–November
• Best outdoor growing period: October–March
• Ideal growing temperatures are 13–24°C.
• Avoid planting during the hot summer months, as high temperatures reduce bulb development.

🌿 Seed Starting

1. Prepare fertile, loose, well-draining soil enriched with compost.
2. Sow seeds 6–12 mm (¼–½ inch) deep.
3. Space seeds 2–3 cm apart in rows.
4. Water gently and keep the soil consistently moist until germination.

⏱ Germination

• Seeds typically germinate in 7–14 days.
• Ideal soil temperature for germination is 18–24°C.

🌱 Thinning & Transplanting

• Thin or transplant seedlings when they are 10–15 cm tall.
• Final spacing:
  • 10–15 cm between plants.
  • 25–30 cm between rows.
• Avoid damaging the roots when transplanting.

☀️ Growing Conditions

• Sunlight: Full sun (6–8 hours daily).
• Soil: Well-draining, fertile soil with a pH of 6.0–7.0.
• Watering: Water regularly to keep the soil evenly moist, especially while bulbs are forming.
• Fertilizing: Apply a balanced vegetable fertilizer every 3–4 weeks until bulbs begin to mature.

🧅 Harvest

• Harvest when 50–80% of the leaves naturally fall over and begin to dry.
• Lift bulbs carefully and cure them in a shaded, airy location for 7–14 days before storage.
• Store fully cured bulbs in a cool, dry, and well-ventilated place.

🌡 Gulf Climate Tips

• Grow only during the cooler months.
• Apply mulch to conserve soil moisture and reduce weed growth.
• Avoid excessive nitrogen fertilizer late in the season, as it encourages leaf growth instead of bulb formation.
• Reduce watering during the final week before harvest to improve bulb quality and storage life.
