Planting & Care

Start American Flag Leek seeds indoors 8-10 weeks before the last frost date. Sow seeds ¼ inch deep in seed-starting mix, keep moist, and provide bottom heat for best germination. Once seedlings are sturdy, harden them off and transplant outdoors after the danger of frost has passed. Space plants 6-8 inches apart in rows 12-18 inches apart. For a continuous harvest, sow seeds successionally every 3-4 weeks.

Leeks require consistent moisture and benefit from a layer of mulch to retain soil moisture and suppress weeds. Hill soil around the stems as they grow to blanch the lower stalks for a longer white section. Fertilize lightly with a balanced organic fertilizer every 4-6 weeks. Harvest when stalks reach desired size, typically 100-120 days from transplanting.
