Growing directions
Sow seeds 1/4 in deep and keep soil moist; germination is similar to common chives but the flat, grass-like leaves have a distinct mild garlic flavor. Grow in well-drained, fertile soil and divide clumps every 2–3 years to prevent overcrowding and maintain productivity. Deadhead flowers promptly, as garlic chives self-seed prolifically and can become weedy. Harvest flat leaves at any height; older leaves become slightly tough but remain useful cooked.
