Select the Right Onion Type: Choose onion sets, seeds, or transplants based on your climate (long-day, short-day, or intermediate varieties).
Prepare the Soil: Ensure well-draining, loose soil enriched with compost, with a pH of 6.0 to 6.8.
Planting: Space onions 4-6 inches apart, with their tops slightly above soil level, in a sunny location.
Watering Needs: Keep the soil consistently moist but avoid overwatering to prevent rot.
Fertilizing: Apply nitrogen-rich fertilizer every few weeks to encourage bulb growth.
Monitor for Pests: Keep an eye out for pests like onion maggots and use organic repellents if necessary.
Harvesting: Harvest when tops yellow and fall over, then cure bulbs in a dry, airy space for storage.
