1 Onion seeds sprout usually within 7 to 10 days. 2  Minimum temperature for sprouting is 55Â°F (12.8Â°C); as the soil temperature increases from 55Â°F to 75Â°F the percentage of seeds sprouting will increase and the time to emergence decreases.3  Onions are adapted to a wide range of temperatures and they are frost tolerant. Optimal onion leaf growth occurs at 68Â° to 77Â°F (20Â° to 25Â°C). 2  Once bulbing has begun onions easily tolerate temperatures higher than 75Â°F. 3  Boltingâthe setting of seed and cessation of bulb developmentâis driven by temperatures between 40Â° to 50Â° (7.2Â° to 10Â°C).
