The peace plant, more commonly known as peace lily or spath flower, is a popular indoor foliage plant and one of only a few plants that produce flowers in low light. Valued for its fragrant white blooms and dark green foliage, peace plant thrives under typical indoor growing conditions with only minimal care. In most cases, peace lily reaches up to 4 feet in height with an equal spread, creating an appealing display in areas where other houseplants may not survive. Several cultivars of peace plant exist, but all have similar care requirements.
Keep peace plant in a location that receives bright, filtered sunlight throughout the day. Maintain a constant temperature of 65 to 85 degrees Fahrenheit during the day and 55 to 65 degrees Fahrenheit at night to prevent cold damage.
Water once every five days to keep the soil slightly moist at all times. Apply room-temperature water to avoid shocking the plant. Decrease the frequency of watering to once every 10 days during winter when the plant is not growing actively.
Wipe down leaves with a clean, damp cloth once every three to four days to remove dust and any potential pests, and to leach out excess fertilizer salts. Be gentle to avoid damaging the delicate foliage and use tepid water for the best results.
Feed once every two to three months using a balanced 20-20-20 NPK fertilizer. Water before and after applying to prevent root burn from the influx of nitrogen. Apply at the rate recommended by the manufacturer.
Repot peace plants once every two to three years to provide additional room for growth and fresh soil. Use a growing medium made of two parts potting soil and one part peat moss. Increase the size of the container by about 3 inches each time.
