When to Plant:
Direct sow seeds as soon as the soil can be worked in the spring. Onion seeds can be started indoors 3-4 weeks before soil can be worked.
Bulbing onions are dependent on day length for bulb production; short-day onions produce bulbs when they receive 11-12 hours of daylight are best for Southern states, long-day onions need 14-16 hours are best for Northernstates.
Use a 10-5-5 fertilizer or something similar. Onions like a lot of Nitrogen.
