• Thinning – Once seedlings are 1 to 2 inches tall, thin to a spacing of 3 inches.

Heirloom Walla Walla Onion Seeds Harvesting Instructions

Walla Walla Onion bulbs are ready to harvest around 100 days from sowing.

To harvest, pull onion bulbs from the ground and cover them with foliage to keep them from getting sunburned. Allow them to dry in the garden for a week.

Next, bring them indoors to cure for 2 to 3 weeks in a warm, dry place with good air circulation. Once cured, store the bulbs in a mesh onion bag or pantyhose in a cool, dry location.
