Onion Sets Dutch - Red Baron (Pack of 75)

Red Baron onion sets are a robust and flavorful choice for gardeners seeking vibrant red onions with excellent storage potential. This long-day variety thrives in northern and central climates, where extended daylight encourages uniform bulb development and rich, crimson skin.

These premium Dutch-grown sets produce medium-sized onions with firm white flesh tinged with pink or purple highlights and a fine, strong flavor. Perfect for fresh use in salads, salsas, and garnishes, they also hold up beautifully in roasted and sautéed dishes. Their reliable growth habit makes them well-suited for organic and sustainable gardening practices.

Plant the sets 1 inch deep and about 4 inches apart in fertile, well-draining soil. Red Baron onions perform best in full sun with consistent moisture and are hardy in USDA Zones 3–9. Their early maturity delivers a uniform harvest that cures and stores exceptionally well, providing a steady supply for months.

Harvest and curing

Long-day onions depend on northern summer day length as well as planting date, so confirm regional fit before planting. Reduce irrigation as tops soften, lift bulbs without bruising, and cure them under cover with steady airflow. Trim only after necks and outer skins are thoroughly dry. Store sound bulbs in a cool, dry place and inspect them periodically. Compare more onion sets by color, day-length response, and pack size.
