How can I properly cut peace lily flowers to ensure their health and longevity?

To properly cut peace lily flowers for health and longevity, use clean, sharp scissors to make a clean cut at the base of the stem. Cut at a slight angle to increase water absorption. Remove any leaves that will be submerged in water to prevent rotting. Place the cut flowers in a vase with fresh water and change the water every few days to keep them healthy and vibrant.
