Growing Coriander in a pot

Coriander has moderate water needs. Keep the soil consistently moist but not waterlogged, especially during germination and early growth. In dry spells from May to August, water two or three times a week; inconsistent watering or drought stress triggers premature bolting. In cooler, wetter months—April and September—natural rainfall is usually sufficient, though check seedlings regularly. Water at the base of plants in the morning to reduce the risk of fungal issues. Feeding is generally unnecessary. Coriander is a short-lived, fast-growing herb that does perfectly well in average garden soil without added fertiliser. Excessive nitrogen encourages soft, lush foliage that bolts even faster and has less flavour. If your soil is very poor or sandy, a light dressing of garden compost before sowing is enough. The database lists no specific feeding months, and none are needed. Coriander is fully hardy across temperate Europe (zone 2–11) and doesn't require winter protection. However, it's usually grown as a warm-season annual for leaves, sown afresh each year from April. Autumn-sown coriander can overwinter in mild areas and provide early spring leaves, but growth is slow in cold weather. Pests are few. Aphids occasionally cluster on young shoots; rinse them off with water or tolerate them, as coriander is fast-cropping. Slugs may nibble seedlings in damp conditions—use barriers or organic pellets if necessary. Coriander is relatively disease-free, though powdery mildew can appear on stressed plants in hot, dry summers. Good spacing, adequate watering, and air circulation help prevent this. Mulch lightly with compost to keep roots cool and moist.
