Walla-Walla Onion Seeds
About- This Walla-walla onion packs a sweet punch! These onions can be planted in the Fall to overwinter for the biggest bulbs and sweetest flavor, or in Spring for a Fall harvest of smaller bulbs. Enjoy fresh or cooked quickly!
When and Where to Plant- Start indoors 10-12 weeks before your last frost. Keep trimmed to 4-6" to prevent them laying over. Transplant into garden around last frost date, taking care not to damage roots. Prefer full sun and well draining soil.
