Chives

Allium schoenoprasum

Herb

Chives are a clump-forming perennial allium with mild, onion-flavoured leaves and edible purple flowers. They are among the easiest herbs to grow, tolerating most conditions and dying back in winter before re-emerging each spring. Dividing the clumps every few years keeps them vigorous and productive.

  • -Perennial - dies back in winter and re-emerges reliably in spring
  • -Remove flower heads promptly to redirect energy to leaves
  • -Cut back after flowering to encourage fresh growth

Issues & threats

Image placeholder

Wilting

Environmental

Plants are drooping or losing vigour. Most commonly caused by water stress but can also indicate root damage, vascular disease, or heat scorch. Identifying the cause quickly is important as some causes are serious.

Image placeholder

Poor germination

Environmental

Seeds are emerging unevenly or not at all. Usually caused by soil temperature being too low, seeds sown too deep, poor seed-to-soil contact, or old seed stock.

Damping off

Fungal disease

Pythium spp. / Phytophthora spp.

Young seedlings collapse at or just below soil level, caused by fungal pathogens that thrive in overwatered, poorly ventilated growing conditions. Can spread rapidly through a seed tray.

Yellowing leaves

Environmental

Leaves are turning yellow, which can indicate a range of problems including nutrient deficiency, overwatering, disease, or natural senescence. Identifying whether the pattern is upper or lower leaves, whole leaves or between veins, is key to diagnosis.

Stunted growth

Environmental

Plants are significantly smaller or slower to develop than expected. May be caused by poor soil, nutrient deficiency, root restriction, compaction, pest damage to roots, or disease.

Image placeholder

Chewing damage

Pest

General chewing damage from an unidentified pest, leaving holes or missing leaf sections. May be caused by caterpillars, beetles, or other insects. Inspect at dusk to identify the culprit.

Sap-sucking pests

Pest

General sap-feeding pest activity causing weakened or distorted growth. May be caused by aphids, whitefly, scale insects, or other sucking insects. Inspect leaf undersides and growing tips to identify the pest.
