How to Grow Garlic Chives from Seed

Know the Difference Between Garlic Chives and Common Chives

Garlic chives are Allium tuberosum. Common garden chives are Allium schoenoprasum. They are related, but they are different species.

Illinois Extension describes garlic chives as having flat leaves rather than the round, hollow leaves of common chives. Garlic chives also produce white flowers and have a distinct garlic flavor.

University of Minnesota Extension likewise identifies garlic chives as Allium tuberosum and notes their flat leaves and fragrant white flowers.

Start Garlic Chives from Seed

Chives can be grown from seed sown in spring. Illinois Extension notes that chive seed can be slow to germinate and that seedlings may require several weeks before they are large enough for transplanting.

Start seed in a clean growing medium that holds adequate moisture while still draining freely. Keep the seedbed from drying completely during germination, and provide strong light after seedlings emerge.

Garlic chives can also be propagated later by dividing established clumps, which makes an existing planting a renewable source of additional plants.

Choose a Sunny Growing Location

North Carolina Extension identifies full sun as the preferred light condition for garlic chives. Illinois Extension also recommends full sun for chives and states that garlic chives can be grown using the same general culture.

A sunny position supports strong leaf growth and flowering. When growing garlic chives near larger vegetables or herbs, make sure neighboring plants do not eventually shade the clumps more heavily than expected.

Garlic chives can also be grown in containers, making it easier to position them where adequate sunlight is available.

Use Soil That Drains Well

Chives tolerate a range of soils, but Illinois Extension reports that they perform best in soil with good organic matter. For garlic chives, drainage also matters because excessively wet conditions can lead to bulb or root problems.

North Carolina Extension specifically notes that bulb rot can occur when garlic chives remain in overly wet soil.

Improve compacted soil before planting, or use a raised bed or container when the existing garden site routinely stays saturated.

Leave Space for the Clumps to Expand

Garlic chives do not remain as individual narrow seedlings indefinitely. They develop into perennial clumps and can gradually occupy more garden space.

University of Minnesota Extension recommends spacing established chive plants approximately 6 to 12 inches apart. Because garlic chives can spread readily, the final layout should also account for access to the plants for harvesting, division, and flower removal.

Avoid crowding plants tightly against permanent structures or slower-growing neighboring herbs if you want to maintain a clearly defined planting.

Water Deeply When Rainfall Is Insufficient

University of Minnesota Extension recommends deep watering when rainfall is infrequent so that the soil does not dry around the chive root zone.

Newly established seedlings and divisions deserve particular attention because their root systems have not yet occupied a large volume of soil.

At the same time, avoid turning routine watering into constant saturation. Check soil conditions before adding more water and make sure containers have functional drainage holes.

Harvest Leaves Without Damaging the Crown

Garlic chive leaves can be harvested similarly to common chives. Illinois Extension recommends cutting chive leaves near the base, approximately one inch above the soil.

University of Minnesota Extension likewise recommends harvesting chives by cutting leaves from the base of the plant.

Regular harvesting supplies fresh foliage and allows new leaves to replace the material that has been cut. Use clean cutting tools and avoid pulling aggressively enough to disturb the crown or roots.

Decide How You Want to Manage the White Flowers

Garlic chives produce white flowers later in the growing season. University of Minnesota Extension notes that the fragrant flowers typically appear later than those of common chives.

North Carolina Extension identifies garlic chives as a pollinator plant and notes that the flowers attract pollinators.

Gardeners can therefore allow selected plants to bloom when flowers and pollinator activity are desired. The tradeoff is that mature flowers can produce abundant seed.

Prevent Unwanted Self-Seeding

Garlic chives can spread aggressively when flowers are allowed to mature and release seed. North Carolina Extension recommends deadheading to prevent unwanted self-seeding.

Illinois Extension has also documented garlic chives spreading rapidly by seed in garden settings and recommends removing flower heads before seed dispersal when expansion is not wanted.

Containers provide another way to keep a planting physically defined, although flower heads can still distribute seed beyond the pot if they are allowed to mature.

Divide Established Clumps as They Become Crowded

Chive clumps enlarge over time. University of Minnesota Extension recommends dividing established chives every three or four years, with spring identified as a good time for division.

Illinois Extension similarly recommends periodic division to keep chive plantings vigorous and prevent overcrowding.

Lift an established clump, separate it into viable sections, and replant those divisions into prepared soil. Division provides a practical way to renew an older planting while creating additional plants.

If the objective is containment rather than expansion, keep only the number of divisions needed and avoid distributing unwanted plants into unmanaged areas.
