How should I properly prune a peace lily to ensure its healthy growth and longevity?

To properly prune a peace lily for healthy growth and longevity, use clean, sharp scissors to trim any yellow or brown leaves at the base of the plant. Remove any dead flowers or stems to encourage new growth. Avoid cutting healthy green leaves, as they are essential for photosynthesis. Pruning should be done as needed throughout the year to maintain the plant's health and appearance.
