It is a short-day onion that can produce mini or pearl onions in long-day areas. The plant is bolt resistant and can be grown in short-day areas to produce medium-sized thick flat white bulbs. When growing Eclipse onions, they should be sown outdoors after the last frost or indoors weeks before the last frost. The recommended planting height is 9 to 15 inches, with a spacing of 9 to 12 inches between plants. The harvest period is typically around 80 to 180 days after planting.
