Planting & Care

Start seeds indoors 8-10 weeks before the last frost date, or sow directly outdoors in early spring once the soil can be worked. Plant 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.

Onions require consistent moisture during the growing season, but reduce watering as bulbs mature to prevent rot. Mulch around plants to suppress weeds and retain moisture. Harvest when tops begin to yellow and fall over, then cure bulbs in a dry, well-ventilated area before storing.
