How to Take Care of a Spathiphyllum Plant
Spathiphyllum (Spathiphyllum floribundum), or peace lily, is a popular indoor plant. It grows outdoors in shaded areas of the tropical regions of the U.S., where freezes are not a problem. Native to the tropical Americas, it grows freely on the floor in rain forests, making it adaptive to low-light conditions and a perfect houseplant. Spathiphyllum is relatively easy to grow and, with proper care, will continue to produce large, white spathe flowers and be green and healthy for years to come.
Repot the spathiphyllum into new soil, if the plant has been residing in the same soil for several years. Use a well-draining potting mix that is high in organic matter. Carefully remove the plant from its container and set it on newspaper. Remove the old soil and wash the container. Place the spathiphyllum back into its container and fill with new soil. Pat the soil down firmly around the plant. Use a container that has drain holes.
Situate your spathiphyllum under the canopy of other plants or trees where it will live in deep shade, if growing it outdoors in warmer regions of the country. It will not survive if planted in an area that receives sunlight, as it will burn up. Grow the plant in a rich, well draining soil amended with compost.
Place an indoor grown spathiphyllum in an area that receives bright, filtered light, for best results. They prefer a warm environment of 65 to 85 degrees Fahrenheit during the day. Do not place the plant by a sunny window where it will burn. Spathiphyllum will tolerate living in lower light conditions, though.
Water the plant with room temperature water that has set out overnight. Allow the soil to slightly dry out and then give it water. Keep the soil moist, but not soggy or flooded, as this can cause yellowing of the leaves. Bottom water the plant.
Fertilize the spathiphyllum with half-strength, water-soluble 20-20-20 fertilizer every other month. Use caution not to fertilize too much, or the leaves and roots can become burned.
Wipe off any dust from the leaves with a damp cloth. This will make the plant look better, help it breathe and will remove any pests that may be present.
Spathiphyllum will bloom more if placed in correct lighting. Plants grown in less light will bloom but not as frequently.
