Believed to originate in Asia, onions have been used in everyday life for centuries.  Considered a cool season biennial, onions prefer to grow at cooler temperatures.  Higher temperatures promote bulbing and curing.  Plant onions early after the last hard frosts so that they can grow during the spring and early summer, producing bulbs as the temperature increases. 

(Tip) Onions: For most onions, start indoors in late February to mid- March.  Soil – Fertile, well drained non-crusting soil.  Onions will adapt well to many soils.  PH 6 – 6.8.  Fertility – Onions use high amounts of nitrogen and potassium.  Even moisture is required throughout its growth period.  Germination – 7 – 10 days at 70F.  Sow directly into final container 6mm / ¼ “ deep.  Trip tops to 10cm / 4” every week until transplanting.  Space transplants 6-8” apart in rows 16” apart.  When onion tops start to fall over and bulbs have begun to form skins, pull up and allow to sun cure for at least one week.  Do not leave out if there’s a chance of frost.  When onions are dry, clip off the tops and place them in shallow boxes or onion bags.  Place in a cool (a few degrees above freezing) somewhat humid place 65-75% humidity.  For bunching onions sow every second week starting in April until September.  This will provide fresh greens until fall.  Sow seeds in well tilled soil.  Space seeds 6mm / ¼ “ apart and 6mm / ¼ - ½ “ deep.  Keep moisture consistent to produce fresh bunching onions.
