Chinese Chives (Allium tuberosum)

How much light does a Chinese Chives need?

Growing Chinese chives outdoors calls for a full sun spot, meaning direct sunlight for six hours or more across the day. That full sun rating is the only light level listed for this species, with no shade tolerance recorded in the facts checked for this page. Choose a planting site that stays open to the sky for most of the daylight hours, matching that full sun requirement outdoors.

• Light: Full sun^1,2,3

Best soil for a Chinese Chives

Chinese chives grow best in soil that drains well but still holds some moisture, rather than soil that dries out completely or stays soggy for long stretches. The recommended soil pH range for this species runs from 6.0 to 8.0, covering slightly acidic through moderately alkaline conditions. Good drainage and a steady, moist feel are both part of the ideal soil described for this plant, not one or the other alone.

• Soil drainage: Well drained and moist^1,2,4
• Soil pH: pH 6–8¹

Hardiness and temperature

This species survives winter outdoors in USDA hardiness zones 3a through 9b, a broad range that spans cold northern gardens and warm southern ones alike. Zone 3a marks its coldest reliable limit outdoors, while zone 9b marks the warmest end of the hardiness range listed for it.

• Hardiness: Zones 3a–9b²

How to plant a Chinese Chives

Outdoor planting calls for a spot that gets full sun, the exposure recorded as this species' preference. This plant survives outdoors through winter across USDA hardiness zones 3a to 9b, a wide span that covers cold and mild climates alike. At maturity, it reaches only about 0.3-0.5 ft (0.1-0.15 m) tall. It spreads to roughly 1 ft (0.3 m) wide, so give each plant that much room when you set it out.

• Hardiness: Zones 3a–9b²

Winter care

Outdoors, Chinese chives survive winter cold reliably within USDA hardiness zones 3a through 9b, the hardiness range documented for this species. Zone 3a represents the coldest end of that range, while zone 9b represents the warmest end where the plant can still be left outdoors through winter. This species is described as a herbaceous perennial that is hardy across that same zone range outdoors.

• Hardiness: Zones 3a–9b²

How to propagate a Chinese Chives

Chinese chives can be propagated from seed or by division, and both methods are described as easy ways to start new plants outdoors. Seed is one option for starting this plant, and splitting an existing planting into divisions is the other, with neither ruled out as difficult. Either approach is listed as a workable way to grow this species from scratch outdoors.

Common problems

Bulb rot is one problem recorded for this plant, and it develops when the soil around the bulb stays too wet for too long. Xanthomonas leaf blight is the other disease listed for this species in plant disease records. Bulb mites are the pest noted alongside those two diseases.
