Plant aeoniums in containers using a loam-based compost with added sharp grit to ensure free drainage. Position in full sun and water with rainwater, if possible, during the active growing season, allowing the compost to dry out slightly between waterings.
Feed monthly with a balanced liquid fertiliser in spring and summer. During their winter dormancy, avoid watering altogether. These succulents are adapted to dry conditions, storing moisture in their fleshy leaves, so take care not to overwater.
As they are not frost hardy, move them to a dry, frost-free space for winter to protect them from cold damage.
