Planting & Care

Sow Sweet Spanish Onion seeds indoors 8-10 weeks before the last frost date for transplanting, or direct sow outdoors once the soil is workable in spring. Plant seeds about 1/4 inch deep and keep the soil consistently moist until germination. Thin seedlings to stand 4-6 inches apart to allow room for bulb development.

Onions require regular watering, especially during dry spells, but avoid overwatering to prevent rot. Mulch around plants to conserve moisture and suppress weeds. Stop watering when tops begin to yellow and fall over, then harvest and cure bulbs in a dry, well-ventilated area before storage.
