Peace Lily Care & Watering

Peace lilies are most likely to flower when they receive sufficient light.

The peace lily, or Spathiphyllum, is a houseplant that requires relatively little care. Peace lilies are among the few houseplants that will produce flowers even when placed in a low-light location, such as a north-facing window.

Exposure

These houseplants grow best in locations with bright, filtered light. Although they will survive in very low-light conditions, they are more likely to produce blooms if given more light. Direct sunlight should be avoided, however, as it can cause the leaves to burn.

Watering and Fertilizing

Peace lilies appreciate a potting soil with good drainage. They do best with soil that is kept moist but never soggy, as too much water can cause the plant's roots to rot. If the plant is allowed to dry out, the leaves may wilt and turn yellow at the edges. Clemson Cooperative Extension recommends using only room temperature water on the plant. Peace lilies require little fertilization, and should receive liquid plant food in spring and summer only.

Problems

The peace lily is sensitive to cold temperatures and should be kept where the temperature is no lower than 60 degrees Fahrenheit. Brown leaf edges may indicate too much fertilizer or too little water. Peace lilies are rarely bothered by pests, but mealybugs may present a problem. They may be eliminated by dabbing each bug with a cotton swab dipped in rubbing alcohol.

Repotting

Repotting is necessary for a peace lily only when the plant begins to crowd its container.
