Planting & Care

Start Yellow Spanish Sweet Onion seeds indoors 8-10 weeks before the last frost date for transplanting, or sow directly outdoors once the soil has warmed and is workable. Sow seeds about 1/4 inch deep and keep the soil consistently moist until germination. Thin seedlings to the recommended spacing to allow bulbs to develop properly.

Provide full sun and well-drained soil throughout the growing season. Water regularly, especially during dry spells, but avoid overwatering to prevent bulb rot. Mulch around plants to conserve moisture and suppress weeds. Stop watering when tops begin to yellow and fall over, signaling that bulbs are nearing maturity. Harvest when tops have dried and pull bulbs for curing.
