Feed with a balanced liquid fertiliser every two weeks until the flowers have faded. Mulch annually in fall with well rotted garden compost or manure. Remove the flower stems after the blooms have faded. Zantedeschia makes excellent cut flowers and have one of the longest vase life among cut flowers (up to 2 weeks).
Zantedeschia grows to around 31.5 inches tall and has fleshy, turnip-like roots (rhizomes). The calla lily can reach stately heights with age and is therefore particularly suitable for large containers. Caution: As with all plants from the Araceae family, the plant parts of the Zantedeschia contain a poisonous liquid.
