Plant in a sunny spot with well-drained soil, ideally in a location sheltered from strong winds. Cardoons thrive in nutrient-rich soil, so adding compost or well-rotted manure at planting time can help establish strong growth.

Water regularly during the growing season, especially in dry spells, but avoid waterlogging. In autumn, leave the faded flower heads intact as they add winter interest and provide some structural beauty in the garden.

To protect the crown, apply a dry mulch, such as straw, during the winter months, which will also help insulate the plant from frost. Prune back any dead stems in early spring to encourage fresh new growth.
