Peace Lily Care

Peace lilies are often cultivated as potted houseplants in the United States, since most climates do not allow for outdoor growth. If you have potted peace lilies, you can take them outside during the summer, but as the temps drop, bring them back inside.

Peace lilies need relatively moist soil, filtered sunlight, and consistently mild weather. Most diseases and pests do not affect these plants, but they are susceptible to scale and mealy bugs. For these pests, spot treatment with horticultural oil is a good strategy.


Peace lilies are shade-loving plants in their natural habitats, but they require a bit more filtered light, but not direct sunlight, when grown indoors. In either case, the plant should be moved to a more shaded area.

Keep peace lilies in a place that receives strong, indirect light. Since the plant will be exposed to the bright morning sun, an east-facing window is ideal. A peace lily would also grow in a north-facing window.


Peace lilies prefer rich, loose potting soil with plenty of organic matter. These plants are native to tropical canopy conditions where the soil is packed tightly with rotting plant waste, soil that reflects this will yield best results.

The plant is sensitive to wet soil conditions, so pick a well-draining mixture and pot the plant in a terracotta or clay vessel that can wick away excess moisture. Use an all-purpose potting soil that drains well. The peace lily will appreciate the refreshed soil if the plants are repotted every few years in the spring.


Peace lilies love to be submerged rather than overwatered, so water them only when they’re dry at least an inch below the surface. Mist peace lilies during the summer they grow in more humidity like found in a rainforest. Reduce watering in the winter, but never let the soil totally dry up. If tap water is severely chlorinated, it is best to use filtered water.


Frequent feedings result in the strongest plant and seasonal blooming for peace lilies. Feed plant weekly over the summer, or use slow-release pellets at the start of the season. During the winter, do not need to fertilize the plant.

Apart from water and indirect sunshine, plant will require no care. It should not be necessary to use fertilizers to grow a healthy, robust peace lily. Green blossoms indicate over-fertilization. If plant displays this symptom, cease fertilizing and reduce fertilizer dose by half the next growing season.

Pests and Diseases

Coreopsis plants grow without incident for the most part. However, during wet seasons, they may become prey to snails and slugs, as well as fungal infections. Try to enhance your plant’s habitat before using pesticides and fungicides.

Make sure it has lots of air circulation to keep pests and fungi at bay. Also, take note of whether it receives adequate sunlight. Overgrown clumps that aren’t receiving enough air or light should be divided.


Peace lily blossoms are grown on stalks that shoot up from the plant’s base. Once a stalk has produced one bloom, it will not produce any more; once the blossom fades, the stalk will turn brown and die.

Pruning a peace lily extends beyond the blossom stems. Sometimes the leaves turn yellow and begin to shrivel. Peace lily pruning should be done near the plant’s base. Cut the stalk near the bottom. This will allow new stalks to grow.

If any of the leaves start to turn yellow or dry out, just snip them off at the base. To avoid the spread of disease, always clean shears between cuts.


The peace lily is propagated by dividing clumps during repotting activities, which can be done at any time of year. Inspect the plant for little branch crowns near the main mother plant; this indicates that the plant is ready to split. Here’s how it’s done:

  • Remove the entire plant from its container, then pull or cut the adjacent crowns apart. Any portion with two or more leaves and linked roots has a good chance of growing.
  • Fill a 6-inch pot halfway with damp but not soggy potting soil.
  • Plant the clumps in the container right away and properly water them.
  • Keep the plant in a warm, well-lit area. The roots should regrow in less than a month.
