Growing Guide

Planting time varies by Australian climate zone. In temperate and cool-temperate regions, plant chives in spring (September–November) or autumn (March–May) to avoid the harshest frosts and summer heat. Mediterranean-climate gardeners in Perth and Adelaide can plant autumn through spring for the longest productive season. Subtropical growers in Queensland and northern New South Wales do best planting in autumn (March–May) when temperatures cool, as chives struggle in intense tropical heat and humidity. Start from seed sown directly into prepared beds or punnets, or transplant seedlings from a nursery. Prepare soil by digging in compost or aged manure to a depth of 20 cm, ensuring good drainage — chives dislike waterlogged roots. They thrive in a slightly acidic to neutral pH of 6.0–7.0. Water regularly but allow the top centimetre of soil to dry slightly between waterings; medium moisture is ideal. Avoid overhead watering in humid subtropical areas to reduce fungal risk. Feed every four to six weeks during active growth with a balanced liquid fertiliser to encourage lush foliage. Harvest by snipping leaves to within 2–3 cm of the base using clean scissors — this promotes fresh new growth. Begin harvesting once plants reach 15 cm tall. Remove flower heads promptly if you want to maintain strong leaf production, or allow some to bloom for pollinators and self-seeding.

🤝 Good Companions

Chives make excellent companions for carrots tomatoes and roses as their sulphur compounds help deter aphids carrot fly and black spot fungal disease. Planting chives near brassicas such as broccoli and cabbage also helps confuse and repel cabbage white butterflies with their pungent scent.

❌ Avoid Planting With

Avoid planting chives near beans and peas as alliums are known to inhibit the growth of legumes and may reduce their yield significantly. Keep chives well away from asparagus beds as well since the two plants compete poorly together over the long term.

🐛 Pests & Diseases

Chives in Australia are generally robust but can be affected by thrips and onion fly in warmer months, causing distorted or silvery-streaked foliage — treat with neem oil spray or insecticidal soap applied in the early morning. In humid subtropical conditions, downy mildew and rust can appear on foliage; improve air circulation by thinning clumps and avoid wetting leaves when watering. Slugs and snails may nibble young shoots, particularly after rain — control organically with iron-based snail pellets or crushed eggshell barriers around the base of plants.

🌱 Fertilising

Feed chives every four to six weeks during the growing season (spring and summer) with a balanced liquid fertiliser such as seaweed and fish emulsion blend to support leafy, vigorous growth. In Australian soils that are often low in trace elements, a slow-release organic granular fertiliser worked into the soil at planting time provides an excellent nutritional foundation throughout the season.

✂️ Pruning & Training

Cut chives back hard to about 2–5 cm above soil level two to three times per growing season to stimulate a flush of fresh, tender new growth and prevent the plant from becoming straggly or woody. Remove spent flower heads promptly after blooming to redirect the plant's energy into leaf production, unless you wish to allow self-seeding across your garden bed.

🔬 Propagation

Chives are most easily propagated by division — simply lift an established clump every two to three years in autumn or early spring, separate into smaller sections of around six to ten bulblets, and replant at 20–30 cm spacing to reinvigorate the plants and expand your patch. They can also be grown readily from seed sown directly into moist, well-prepared soil in spring or autumn, germinating within ten to fourteen days under warm Australian conditions.
