Why Do the Ends of Peace Lily Leaves Turn Brown?

The peace lily (Spathiphyllum spp.) is a tropical plant commonly grown as a flowering house plant. Though largely resistant to pests, peace lilies commonly produce brown leaves due to poor cultural conditions.

Keep plant in bright sunlight.

Peace lilies are extremely sensitive to their environment and often drop leaves when moved to a new location. Grow peace lilies in bright, indirect sunlight to keep leaves from getting scorched.

Water plants indoors.

Peace lilies may produce brown leaves when given too much or too little water. Water the plant deeply and evenly whenever the soil is dry to the touch, and mist a little warm water on the leaves.

Prevention

Use house fertilizer.

Prevent peace lily problems by following proper care requirements. Regularly wipe down the plants leaves to remove dust and grime that may inhibit the plant's ability to take in sunlight, and use a balanced houseplant fertilizer every two to three months.
