Onions are celebrated for their nutrition and usefulness in the kitchen. These delicious vegetables provide a rich source of vitamins, minerals, and antioxidants. Cultivated for thousands of years, onions originally come from Central Asia. Because of their versatile use, onions have spread across the world, and can be grown outdoors in USDA hardiness zones 3 to 9. Planting times vary based on the variety and local climate.


Knowing when to start onion seeds is key to their successful cultivation. Find an area that receives full sunlight with fertile, well-drained soil. Sow onion seeds directly in the garden in early spring. Alternatively, start indoors 6 to 8 weeks before the last frost date. Plant the seeds about a quarter-inch deep. Spacing should be done according to the desired bulb size and instructions on your packet. Keep the soil consistently moist to encourage germination, which usually happens within 10 to 14 days.


Once onion seedlings have been established, they require minimal maintenance. Thin them out to prevent overcrowding. Regular watering is essential, especially during bulb formation, but be cautious of overwatering to prevent rot. Harvesting can start when tops begin to yellow and fall over. Curing onions in a warm, dry place enhances their flavor and storage life.
