Planting & Care

Start Southport Red Globe Onion seeds indoors 8-10 weeks before the last expected frost date. Sow seeds about 1/4 inch deep in a seed-starting mix, keeping the soil moist and at a temperature of 65-75°F for best germination. Once seedlings are sturdy and danger of frost has passed, harden them off and transplant into the garden. Space plants 4-6 inches apart in rows 12-18 inches apart, setting them just deep enough so the roots are covered and the tops are above soil.

Onions require consistent moisture during the growing season, especially while bulbs are forming. Reduce watering as bulbs mature and tops begin to yellow. Stop watering altogether once tops fall over to allow bulbs to cure. Harvest when necks are dry and tops have toppled, then cure bulbs in a warm, dry, well-ventilated area for 2-3 weeks before storing in a cool, dry place. With proper curing, these onions can store for several months.
