How to Grow Garlic Chives Seeds (Allium tuberosum):
Garlic chives are easy perennial herbs with flat, garlicky leaves and white star flowers. Start seeds indoors 6–8 weeks before last frost, or direct sow outdoors in spring once soil is workable; in hot climates, sow during the cool season (fall–winter) for best results. Sow seeds about 0.5 cm (¼ in) deep in a loose, well-drained mix, keep the surface evenly moist, and expect germination in 7–14 days. Give full sun for strongest growth, though light shade is fine in warm areas. When seedlings are a few inches tall, thin or transplant to 15–25 cm (6–10 in) apart; they’ll expand into clumps over time.
How to Care for Garlic Chives:
Water regularly during establishment, then water when the topsoil dries—garlic chives like steady moisture but hate soggy roots. Feed lightly with compost or a balanced fertilizer in spring; a second light feed mid-season helps after heavy harvesting. Harvest by cutting leaves 2–3 cm above the base, taking no more than one-third of the clump at a time so it regrows quickly. Remove flower stalks if you want more leaves, or let them bloom for pollinators and seed saving. Every 2–3 years, divide crowded clumps in spring or fall to keep plants vigorous. They’re cold-hardy, usually die back in winter, and return strongly in spring.
