Learn how to grow yellow onions from seed, choose the right variety, and encourage healthy bulb development.
Sow yellow onion seeds in loose, fertile, well-drained soil and keep the growing medium evenly moist during germination. Provide full sun after seedlings emerge, control weeds, and thin plants according to the variety's spacing requirements. Choose a variety suited to your region's day length for proper bulb formation.
Short-day onions begin forming bulbs with roughly 10–12 hours of daylight, while long-day onions generally need about 14–16 hours. Intermediate-day varieties typically require around 12–14 hours. These ranges vary by cultivar, so select yellow onion seeds according to your growing location and the supplier's recommendations.
Yellow onions commonly need around 90–120 days from sowing to harvest, although some varieties take longer. Growing conditions, planting season, and day-length requirements affect maturity. Harvest when bulbs have developed and the tops begin to yellow and fall over naturally, then cure the bulbs in a dry, ventilated place.
