Q.What Should I Do With My White Calla Lily?
Hi, I’m Yan from Malaysia. I grew this calla indoors since about a month ago. For now, the tips of flowers and leaves are turning to crispy brown (As picture shown). Soils is dry and they stop growing about appx 2 weeks back. Are they in dormant phase or they lack or watering/nutrients?

You can cut off the spent blooms. When the foliage dies back, you can cease watering and move the container to a dark place for its dormant period. Here is more about the care of calla lilies:
