Japanese peace lily (Spathiphyllum), also known as the closet plant, is valued for its ability to survive in shady nooks and dark corners. Give Japanese peace lily a little light, and the plant will produce fragrant, lily-like blooms that are pale green when they open, eventually turning to a shade of creamy white. The foliage consists of large, dark green leaves. Japanese peace lily is a sturdy, low-care plant that is lovely enough to interest seasoned pros or beginning gardeners.
Plant your Japanese peace lily in a container filled with any general-purpose, commercial potting soil. Use a sturdy container with at least one drainage hole in the bottom.
Water your Japanese peace lily when the top of the soil feels slightly dry. Don't allow the soil to become bone dry, as dry soil can cause the foliage to wilt and turn yellow. Water only until the soil is damp, and don't water so much that the soil become soggy. Mist the peace lily at least once or twice every week to increase the humidity. Always water your peace lily with lukewarm water.
Place your Japanese peace lily in low light or bright, indirect light 1 to 1.5 metres (3 to 4 feet) from a window, or filtered by a sheer curtain. Avoid placing your plant in bright, direct light, which may burn the leaves.
Feed your Japanese peace lily once every two to three months, using a regular fertiliser for indoor plants. Don't feed your plant during the winter months. Refer to the package label for specific rates of application. Don't worry if you occasionally forget to fertilise, as Japanese peace lily isn't a heavy feeder.
Keep your Japanese peace lily in a relatively warm room. Temperatures should be between 20 and 28 degrees C (68 and 84 degrees Farenheit) during the day. Nighttime temperatures shouldn't fall between 15 to 16 degrees C (60 degrees F), as Japanese peace lily is a tropical plant, susceptible to damage caused by cold temperatures.
Remove dust from the leaves of your Japanese peace lily as needed. Use a soft cloth that has been slightly dampened.
