The Garlic Chive Seeds are an heirloom product. The are referred to as Allium tuberosum. They are tolerant to winter and they are great for greenhouse production. They have a wonderful garlic flavor and are popular with Asian chefs.
Garlic chives grow well in a variety of soil types, though they prefer moist, well drained soil. They grow well in full sun or partial shade. In short growing seasons, the seed can be started indoors in a flat. Provide bottom heat for fastest germination. To direct sow, plant the seeds after the last frost of spring 1/4″ deep in rows 18″ apart, thinning to 6-8″ apart as soon as the seedlings appear. Germination should take place within 14 days. Garlic chives also grow well as a container plant. For companion planting benefits, plant garlic chives with carrots; this improves the carrots’ flavor and production.
Keep the soil moist while the seedlings are developing. Garlic chives will spread vigorously with each year of growth, and can easily be divided for new plantings. To prevent the plant from reseeding itself, be sure to remove the developing seed heads and keep the plant trimmed. To blanch the developing leaves, cover the plant with a thick layer of straw. After several frosts, cut the plant down to the ground.
