Peace lilies (Spathiphyllum), also known as closet plants, are a popular choice for offices and homes. When it comes to indoor plants, peace lily plants are some of the easiest to care for. But, while peace lily plant care is easy, proper growing conditions are still important. Like many popular indoor plants, peace lilies enjoy medium to low light. Which kind of light you need to provide will depend more on what you want your peace lily plant to look like. Peace lilies that are placed in more light tend to produce the lovely white spathes and flowers more, while peace lilies in low light will bloom less and will look more like a traditional foliage.
One of the most common mistakes in the care of peace lilies is overwatering. Peace lilies are far more tolerant of underwatering than overwatering, which is one of the most common reasons for a peace lily to die. Because of this, you should never water peace lily plants on a schedule. Rather, you should check them once a week to see if they need to be watered.
