How to grow
Cultivation
Grow in peat-free, loam-based potting compost in full light. When in growth, water freely and apply a balanced liquid fertiliser every 2-3 weeks. Calla lilies need a period of dormancy over winter, with little or no water. Once the leaves die down after flowering, move them to a dry, frost-free, preferably dark location until spring. See Zantedeschia cultivation
