How to prune zantedeschia 'crystal blush'

Deadhead spent blooms immediately; cut foliage back once it yellows naturally post-bloom. Cut spent flower stems at the base once the spathe fades. Leave all green foliage intact until it yellows naturally. Then cut the entire plant back to ground level and allow the rhizome a dry dormancy period before resuming watering.
