How to grow coriander
Regularly sow coriander seed 0.5cm deep then thin seedlings to 5cm apart if you're growing for leaves, or 20cm apart if you're growing for seeds.
Choose well-drained soil in a sunny site.
Young broad coriander leaves can have an unpleasant smell so avoid growing indoors. The scent can repel aphids and carrot root fly. Stake flowering stems for support.
Harvesting and using coriander
Pick young coriander leaves before flowering for use fresh. Gather aromatic coriander seeds after the seedheads ripen in summer. Ripening can be sudden so keep a close eye on them.
Coriander plants dislike being transplanted.
