Onion, Walla Walla

Walla Walla is the famous sweet onion from Washington State—so mild and sweet you can bite into them like apples. These jumbo onions are perfect for fresh eating but don't store long, so enjoy them in summer.

Onion: Transform tiny transplants into generous, pungent bulbs right in your garden! These kitchen workhorses swell through photoperiod-dependent bulbing, so selecting the correct variety for your latitude is critical: long-day types for northern growers (bulbing at 14-16 hours), short-day types for the south (bulbing at 10-12 hours), and intermediate types in between. Choose storage varieties for months of keeping, or sweet varieties like Walla Walla to enjoy fresh.

• Growing Tips: Transplant 4-6 weeks before last frost, spacing 4-6 inches apart; ensure latitude-appropriate variety selection (long-day for north, short-day for south).

• Sun Requirements: Full sun (6 hours minimum).

• Preferred Soil: Loose, well-drained, fertile soil; maintain consistent moisture until bulbing begins.

• Harvest Details: Harvest when tops fall over naturally (typically 90-120 days); cure bulbs in a warm, dry location for 2-3 weeks before storage; properly cured storage varieties keep for months.
