Description

Yellow Rock Onion is a dependable heirloom onion variety valued for its firm bulbs, rich flavor, and excellent storage quality. The round, golden-skinned onions develop crisp white flesh with a balanced taste that becomes sweet and savory when cooked, making them a versatile staple in the kitchen.

This hardy variety performs well in a wide range of growing conditions and produces uniform bulbs with strong keeping ability. Yellow Rock Onions are ideal for fresh use, roasting, soups, sautés, and long-term winter storage, offering reliable harvests for home gardeners and market growers alike.

Onion sets are small dormant onion bulbs that offer a faster and easier alternative to starting onions from seed. Sets establish quickly, require less maintenance during early growth, and are especially helpful in regions with shorter growing seasons. They provide more reliable bulb formation, mature earlier, and are less sensitive to uneven germination or spring weather fluctuations, making them an excellent choice for beginner and experienced gardeners alike.

• Type: Biennial grown as an annual (Allium cepa)
• Plant sets: Early spring as soon as soil can be worked
• Sun: Full sun
• Spacing: 4–6 inches
• Days to maturity: 80–100 days from sets

Onions grow best in fertile, loose, well-drained soil with steady moisture throughout the growing season. Keep beds weed-free to reduce competition and encourage strong bulb development. Harvest once tops begin to yellow and fall over, then cure bulbs in a warm, airy location before storing in a cool, dry place for long-lasting use.
