Although the name implies that closet plants are plants that you can stick in a dark room and ignore, Spathiphyllums require more care (and light) than a closet will provide. Often called peace lilies, closet plants are hardy, easy-to-grow tropical foliage plants that are popular with people who want no-fuss greenery in their homes or offices. Along with having attractive, glossy green leaves and creamy white spathes, these plants also remove toxins from the air, according to information published by the University of Florida. With proper care, these tropical beauties will last a long time.
Plant or place your closet plant in a location where it will receive bright, indirect light. While the plant will grow in low-light conditions, it does best with some exposure to indirect sunlight, such as that filtered through curtains or through the canopy of a deciduous tree. Direct sunlight will scorch the leaves of the closet plant.
Plant your closet plant in potting medium that is loose and well-draining, such as one composed of a large amount of peat moss and coarse sand. Closet plants also need soil that is rich in organic materials, according to information published by Michigan State University.
Water enough so that the soil is barely moist. Empty the water catch-tray beneath potted closet plants immediately after the plant stops draining. Let the soil dry out slightly between waterings. Never over-water this plant. Too much water in the soil can cause root rot, a fungal disease that destroys the roots of the plant.
Keep the air around the closet plant warm and humid. Do not place Spathiphyllum plants near any cold or hot drafts. Rest potted plants on tray filled with pebbles and a small amount of water to provide humidity.
