Assorted-Spathiphyllum-plants-Deeper-GreenPeace lilies, also called Spathiphyllum, or Spath, for short, are known for their vibrant green foliage and white flower-like blooms whose curve is as graceful as it is distinct. Though elegant, peace lilies are not delicate. They are hardy, and they can be quite forgiving — both admiral traits in a houseplant. A peace lily will improve the air quality indoors by removing key pollutants, but it will drop pollen on your desk or table, and it may irritate your hands if handled. In this article, we will discuss the key components in caring for your peace lily indoors in medium and low light.


Peace lilies do well as interior plants, and it is best that they do not experience drastic changes in temperature. They thrive when kept within a temperature range of between 65 and 80 degrees Fahrenheit, and it is not recommended that you place your peace lily where there is a draft or directly under an air conditioning vent.

Soil and Potting

Your peace lily will benefit from being placed in humus-rich soil that has already been moistened. Keep in mind that as your plant grows it will need to be moved to a larger pot. If you’ve noticed a droopy appearance after watering, and if the greenery seems crowded, these are indications that a transplant is in order. A good rule of thumb is to move your plant to a container that is at least 1/2-inch larger than the previous space and generally not to exceed 10 inches across. This is a good time to create new peace lilies by using a knife to divide upward from the roots until you have two separate plants.


Annual fertilizing is usually sufficient for the growth of your indoor plants — apply fertilizer any more than this, and you’re likely to cause brown spots to appear on the foliage. Peace lilies are particular about the fertilizer you use, and it is recommended that you go with an organic plant food such as sea kelp, compost tea or regular compost. Well-balanced liquid solutions can be used and watered down if your plant does not respond well to them initially.


When placed in medium and low light as part of your interior landscape, your peace lily should grow and produce a lovely deep green frondescence. That said, you are less likely to see the quintessential white blossoms the less light your plant is exposed to. Direct sunlight, however, can damage leaves, giving them a burned-out appearance.


It is far easier to harm a peace lily through watering it too much than from watering it too sparingly. On average, you can water your plant once a week and spritz the leaves occasionally to keep them hydrated. Test the soil to see if it is dry before watering your plant, as moist soil is an indication that your plant does not need to be watered. Peace lilies need adequate drainage to prevent the roots from developing dry rot.

Other Considerations

Peace lilies contain a toxin in their foliage that can be harmful to children and pets if ingested, so it is good to place your plant somewhere out of reach. You will also want to dust off your peace lily’s leaves periodically and spritz them with insecticidal soap as needed. You can also choose to forgo the watering, fertilizing and planting by placing your peace lily in a vase with water and a single colorful Siamese Fighting Fish also known as a betta fish, making sure to change the water twice a month. The fish emulsion feeds the plant and the plant aides in keeping the water relatively fresh for a single fish.
