Days to Maturity

100 Days to Maturity. Certified Organic.

Beautiful red onion that stores exceptionally well throughout the winter. Subtle sweetness and pungent flavor make it delicious to cook with. Bulbs reach 4" across.

Transplant. Start indoors 8 weeks before last frost and plant out after they reach 5-6" tall, around 4 weeks before last frost. Keep onions evenly watered throughout growing season. Harvest when foliage begins to flop, then allow to dry and cure in a dry area out of direct sunlight. Can easily store until March in cool, dry, and dark conditions.
