How to prune zantedeschia elliottiana

Deadhead during bloom season; foliage cut-back in late summer once yellowed. Cut spent flower stems at soil level as each bloom fades. When all foliage has yellowed naturally, cut it back to the ground. Store rhizomes dry in a cool, frost-free spot over winter if not hardy in your zone.

Deadhead as blooms fade; annual dormancy cut-back. Zantedeschia elliottiana (yellow calla lily) needs deadheading to extend the flowering display and prevent energy going to seed. After all flowers fade, cut stems to the base and gradually reduce watering until foliage yellows. Cut foliage back at dormancy. Do not prune green leaves early — they fuel rhizome recovery for next year's bloom.
