Long-Day Onions in Georgia: Why They Won't Bulb and What to Plant Instead

'Sweet Spanish Yellow Utah Jumbo' is a long-day onion variety that requires summer day lengths found in northern latitudes to form bulbs. In Georgia's heat, these onions succumb to disease and heat stress long before bulbing. Planted in winter, they'll only produce green onions (scallions).

For successful Georgia onions, choose short-day or intermediate-day varieties: 'Walla Walla', 'Yellow Globe Danvers', 'Grano', 'Granex', or 'Juno'. Your Utah-suited seeds were likely stocked by a retailer unfamiliar with regional adaptation—caveat emptor!
