Why do peace lily leaves turn yellow?

Peace lily leaves turn yellow because they are about to die, usually due to too much or insufficient water. This can also happen because the plant was potted too deep when it was replanted after purchase. If the plant is potted too deep, the roots can begin to rot.

To ensure the peace lily stays healthy, it is important to keep it in a humid environment. The air around the plant should be misted, and the soil needs to remain moist. Peace lilies should be watered once a week, or every other week if it does not get a lot of light where it is being stored.
