Choosing the Right Variety
Onions come in many varieties. Some popular types include:

Preparing the Soil
Onions prefer well-drained, fertile soil with a pH of 6.0-7.0. Here�s how to prepare your soil:
- Loosen the Soil: Till the soil to a depth of 8-10 inches (20-25 cm). Remove any stones or debris that could impede root growth.
- Add Compost: Mix in 1-2 inches (2.5-5 cm) of compost to improve soil fertility and structure.
Planting Seeds, Sets, or Transplants
Onions can be grown from seeds, sets, or transplants. Here�s how:
- Seeds: Sow seeds 1/4 inch (0.6 cm) deep in rows spaced 12-18 inches (30-45 cm) apart. Thin seedlings to 4-6 inches (10-15 cm) apart once they have a few true leaves.
- Sets: Plant sets 1 inch (2.5 cm) deep and 4 inches (10 cm) apart in rows spaced 12-18 inches (30-45 cm) apart.
- Transplants: Transplant seedlings outdoors after hardening off, spacing them 4-6 inches (10-15 cm) apart in rows spaced 12-18 inches (30-45 cm) apart.
Watering and Care
Onions need consistent watering and care. Follow these tips:
- Water Regularly: Keep the soil consistently moist, but not waterlogged. Water in the morning to reduce evaporation.
- Mulch: Apply a 2-3 inch (5-7.5 cm) layer of mulch around the plants to retain moisture and suppress weeds.
Fertilizing
Onions benefit from regular fertilization. Use a balanced fertilizer (10-10-10) every 3-4 weeks.
Harvesting
Onions are ready to harvest when the tops start to yellow and fall over. Here�s how to harvest:

- Curing: Allow onions to cure in a warm, dry, and well-ventilated place for 2-3 weeks. Store cured onions in a cool, dry place.
- In the Fridge: Store fresh onions in a plastic bag in the refrigerator crisper drawer. Use within 1-2 weeks.
