10 Reasons Your Calla Lilies are Dropping or Wilting
What is the lifespan of a calla lily?
Available year-round, calla lilies should stay fresh for 7 to 10 days. In terms of care, they're very different than other cut flowers.
Where do you cut calla lilies?
Use a clean, sharp tool to cut calla lily flower stems. Make cuts near the base of the plant, so the cut stem won't be sticking up. Removing flower stems does not hurt the plants. The only other pruning that calla lilies require is removal of leaves as they turn yellow and die.
