How do you force open a cut calla lily?

To force open a cut calla lily, place the stems in warm water and allow them to hydrate for several hours. Afterward, gently expose the buds to a warmer environment, such as near a sunny window, to encourage blooming. You can also lightly wrap the buds in a damp paper towel to maintain moisture while they open. Be patient, as it may take some time for the flowers to fully unfurl.
