How to prune zantedeschia pentlandii

Deadhead during flowering; full cut-back when foliage yellows after bloom, typically mid to late summer. Remove spent flower stems at the base. After die-back, cut all foliage to soil level with clean, sharp pruners. Allow the soil to dry considerably during dormancy — Z. pentlandii is more drought-tolerant than hybrid callas.

Deadhead as blooms fade; annual full cut-back. Zantedeschia pentlandii, a yellow-spathed South African species, is deciduous and dies back after flowering. Deadhead spent spathes at the stem base during the bloom period. Once foliage yellows and naturally senesces, cut all growth back to ground level. The rhizome needs a dry rest period — avoid overwatering stumps.
