Planting & Care

Sow onion seeds indoors 6-8 weeks before the last frost date, or directly in the garden after the danger of frost has passed. Plant seeds about 1/4 inch deep and keep the soil consistently moist until germination. Once seedlings are established, thin them to the recommended spacing to allow proper bulb development.

Onions require full sun and well-drained soil. Water regularly, especially during dry spells, but avoid overwatering to prevent bulb rot. Mulch around plants to conserve moisture and suppress weeds. Harvest when the tops begin to yellow and fall over, then cure the bulbs in a dry, well-ventilated area before storing.
