Harvesting: When onion tops have fallen over and turned yellow or brown, they are ready for harvest. Harvest in the morning, lifting onions with a garden fork. Dry them in the garden in the sun for 2 to 3 days, lightly covering the bulbs with straw, or the tops of other onions to prevent sunscald. Cure onions for 3 to 7 days in a dry area with good air circulation. Once dry, cut the roots to 1/4", and the greens to 1" to create a seal, preventing decay.

Owner Response: Hi Mark, We would love to help! Feel free to contact us with growing issues so we can help troubleshoot issues. It is important to use fresh onion seeds as they don't have a long storage life. When a seedling dies we look to the growing condition to see what when wrong since the seed performed its job. Please feel free to contact us when issues arise so we can help you have a great garden.
