Growing Tips & Guides

Get Started

Allium cepa

Days to maturity are calculated from date of direct seeding.

Direct Sowing
• Thin to the strongest plant when 4-5 inches

Transplanting
• Sow up to 10-12 seeds in a 4-6 inch pot
• If tops reach over 5 inches before transplant, cut to 3 inches
• When planting out carefully separate the seedlings and place in a shallow trench
• Fill trench around seedlings and water in well

How do onions grow and how do I get bigger bulbs?
• Onions are photoperiodic plants — they regulate their stages of growth by day length
• Onions will make top growth until the critical light duration is reached, then bulbing begins
• The amount of growth and development prior to bulbing will determine the bulb size

Should I get short-day, long-day, or day-neutral onions?
• Long-day varieties do well in northern states where summertime day length is between 14-16 hours.
• Short-day varieties do well in southern states and bulb when day length is 10-12 hours; they won't get very large in northern states.
• Dividing line between short-day and long-day varieties is generally accepted as 36° latitude, roughly along the Kansas/Oklahoma border.
• Day-neutral and intermediate-day varieties start bulbing when day length is 12-14 hours; can be successfully grown anywhere.
