Planting & Care

Start seeds indoors 8-10 weeks before the last frost date, or sow directly in the garden in early spring. Plant seeds 1/4 inch deep in well-drained soil. Keep the soil consistently moist during germination, which typically takes 7-14 days. Once seedlings are established, thin to 4-6 inches apart to allow room for bulb development.

Onions require regular watering and benefit from a layer of mulch to conserve moisture and suppress weeds. Stop watering when the tops begin to yellow and fall over, signaling that bulbs are nearing maturity. Harvest when necks are dry and skins are papery, then cure in a warm, dry, well-ventilated area before storing.
