Short-Day Onions

Lower latitudes experience less variation in day length than higher latitudes, and onions bred to perform under these conditions are known as short-day onions. These onions are generally sown in the fall and harvested the next spring, and receive their cue to start bulbing when day length reaches 10–12 hours. Growing short-day onion varieties at higher latitudes than their suggested region will generally result in smaller bulbs.

See our Full-Size Onion Comparison Chart to review characteristics and determine which short-day onions to grow.
