Some African lilies are more durable than other in which case they can be left outside all year in milder areas making sure they receive a generous amount of mulch like chipped bark for protection.
African lilies in containers should be potted up using a loam-based compost and planted with their crowns approximately 5cm below the surface of the compost. Once they start actively growing water them freely but less in winter when they are dormant. These flowers will need the aid of balanced liquid fertiliser (plant food) from the beginning of spring until they start to flower.
