Overview
Growing dill beside the right neighbour
Dill (Anethum graveolens) is a herb in the Umbellifer family. Feathery-leaved herb used for cooking and beneficial insects.
Dill is a magnet for hoverflies, but keep it clear of carrots; flowering dill stunts them.
Give plants 12–18 in in full sun. Aim for well-draining, moderately fertile. In most gardens the crop sits in USDA zones 2-11 and is ready in about 45-70 days.
