HOW TO GROW ONION
Start indoors 8–10 weeks before last frost, plant out 4 weeks before frost. For fall harvest, transplant 11 weeks before first frost. Short-day onions produce bulbs in 11-12 hours of light, long-day onions in 14-16 hours. The dividing line is 36˚, about the KA/OK border. Plant long-day varieties north of this line and short-day south. Direct sow thickly as soon as soil can be worked. If tops reach 5” before transplant, cut to 1-3” to increase girth. Transplant seedlings in shallow trench 2-7” apart. Hill sides slightly after 4-5 weeks. Knock the rest of the tops over when 60 percent have fallen. After 3 days, pull and sun-cure 7–10 days in field rotating every few days before twisting off tops and storing. Soil pH 6.2-7.5. Hardiness zones 3-10. Biennial.
