Allium cepa "Yellow Sweet Spanish"

Yellow Sweet Spanish onions are a type of onion that is known for their mild, sweet flavor and large size. They are typically yellow in color and have a flat or slightly rounded shape, with a diameter that can range from 3-5 inches (7.5-12.5 cm) or more.

These onions are commonly used in cooking and are especially popular for use in dishes where their mild flavor can complement and enhance other ingredients. They are often used in salads, soups, stews, and other savory dishes. They can also be grilled or roasted, which brings out their natural sweetness even more.

Yellow Sweet Spanish onions are grown in many parts of the world, but are particularly associated with the southern United States, where they are a popular crop. They are typically harvested in the summer and fall months, and can be stored for several weeks or even months if kept in a cool, dry place.

Overall, yellow sweet Spanish onions are a versatile and flavorful ingredient that can add a lot of depth and complexity to a wide variety of dishes.

🌱 Planting Instructions 

Approx seeds per order 750

Plant onions in early spring to be harvested in the fall. They have long growing seasons and usually can withstand a light frost.

Start seeds indoors since they need a soil temperature around 50F to germinate. Once it gets warmer outside and the ground can be worked, transplant seedlings outdoors. Space transplants 4-6" apart in rows 12-18" apart. The plants will need about 1" of water per week. Onions are ready to harvest when the tops turn yellow and start to fall over.

Long Day vs. Short Day Onions:

This designation refers to the amount of daylight the onions need during the summer to form bulbs. Onions are sensitive to amounts of daylight and since different parts of the country receive different amounts of daylight during the summer, onions have been bred to accommodate that. An imaginary line was drawn across the United States, stretching from between the border of North and South Carolina to San Francisco. If you live south of that line, plant short day onions. And, if you live north of the line, plant long-day varieties. There are Day-Neutral or Intermediate varieties, as well, which can grow in any location.
