They are best grown in USDA zones 2-9. Soil: Red Grano onions prefer well-drained soil with a pH of 6.0-7.0. If your soil is heavy clay, you can improve drainage by adding sand or compost. Planting: To plant Red Grano onions from seed, sow the seeds 1/4 inch deep and 2 inches apart in rows 12-18 inches apart. If you live in a short-season climate, you can start the seeds indoors 6-8 weeks before the last frost date in your area. Transplant the seedlings outdoors after the last frost date, spacing them 12-18 inches apart in rows 12-18 inches apart. Watering: Onions need about 1 inch of water per week. Water the onions deeply, so that the water reaches the roots. Fertilizing: Onions are heavy feeders, so it is important to fertilize them regularly. Fertilize the onions every few weeks wit
