Harvesting Chives

Chives are low-maintenance once established, but consistent moisture and a light feeding regime keep them lush and productive. Water moderately throughout the growing season, aiming to keep the soil evenly moist but not saturated. In dry spells—especially during May to August when you're harvesting regularly—water once or twice a week. Chives tolerate short dry periods but the leaves become tough and sparse without adequate moisture. In autumn and winter, rainfall is usually sufficient and the plant becomes dormant. Feed once in April as growth resumes. Scatter a general-purpose granular fertiliser (such as blood, fish and bone or Growmore) around the base of each clump, or apply a liquid feed if growing in containers. Avoid high-nitrogen feeds later in the season, which can promote soft growth vulnerable to winter cold, though chives are extremely hardy (zone 3a–9b) and rarely suffer frost damage. Mulch lightly with garden compost in spring to suppress weeds and retain moisture, but keep mulch away from the crown to prevent rot. Chives have few pest or disease problems. Occasionally rust (orange pustules on leaves) can appear in humid conditions—remove affected foliage promptly and improve air circulation. Aphids sometimes cluster on flower stems; a strong jet of water or an insecticidal soap usually resolves this. Chives die back completely in winter. Leave the dead foliage in place until early spring to protect the crown, then clear away the old growth as new shoots appear. Clumps become congested after a few years; lift, divide, and replant in spring to rejuvenate them.
