Why Your Onions Only Produce Scallions

Onion bulbing is triggered by day length. Georgia requires "short-day" or "intermediate-day" varieties. Long-day onions (common in northern stores) will only produce green tops (scallions) here because our summer heat arrives before the long days needed for bulbing.

Plant adapted varieties like 'Walla Walla', 'Yellow Globe Danvers', 'Grano', 'Granex', or 'Juno' in fall or early winter for full-sized bulbs next spring.
