My Peace Lily Flowers Are Turning Brown

Peace lilies may turn brown if grown in poor conditions.

Also known as white flag, the peace lily (Spathiphyllum spp.) is an exceptionally popular plant often grown indoors. One of the most common peace lily problems is wilt and browning leaves.

Causes

Browning may be caused by a wide variety of cultural factors. Peace lilies prefer indirect, filtered sunlight to full sunlight, which may dry out leaves. Excessive fertilizing and water-logged soils may also cause the plant to brown.

Treatment

Remove dry, brown leaves from the plant and wipe down remaining leaves to remove dust. Mist foliage with warm water, and water deeply if the soil is dry to the touch. Move the plant if necessary to a less sunny location.

Prevention

Help prevent peace lily problems by maintaining a stable environment once the plant is established. A temperature between 60 to 85 degrees is ideal for this plant. Fertilize every two to three months with a balanced house plant fertilizer, watering the soil first to prevent the roots from burning.
