Onions, scientifically known as Allium cepa, are herbaceous biennials typically grown as annuals for their edible bulbs. The plant features a flattened disc-like stem at its base, with tubular leaves forming a pseudostem. These plants produce pink or white flowers and develop bulbs composed of several layers, protected by a papery coat. Our yellow variety yields bulbs approximately 3 to 4 inches in diameter. With proper care, onion plants can reach a height of up to 20 inches, providing a satisfying harvest for your culinary needs.

Achieving a successful sweet onion harvest is straightforward with the right conditions. These plants thrive in full sun exposure, which is crucial for optimal bulb development. They prefer fertile, moist but well-drained soil, such as clay or silt loams, with a pH range of 5.5–6.5. Optimal growing temperatures are between 55–75 °F, making areas with cool spring weather and drier, hotter summers ideal for cultivation. These sweet onion seeds are suitable for USDA Hardiness Zone 7 or farther south, ensuring they can flourish in a wide range of climates.

Planting and Care Instructions

Planting your sweet onion seeds is simple. You can direct seed them 4–6 weeks before the last frost date, or start them indoors even earlier for transplants. Sow seeds 1 inch deep, allowing 4-5 inches between plants and 12–18 inches between rows. After planting, water thoroughly and then once every week, applying approximately 1 inch of water each time. Germination typically occurs within 7 to 10 days, with mature bulbs ready for harvest in 3 to 5 months. Onions require a high source of nitrogen; apply fertilizer about three weeks after planting and continue every 2 to 3 weeks until the neck softens. Enjoy the satisfaction of growing your own delicious sweet onions!
