A peace lily plant makes an easy houseplant due to its light and soil requirements. If you place a peace lily plant in a sunny location, you may be fortunate enough to see beautiful white blooms. Placed in a location with less light, the peace plant will still thrive, but it is not likely to bloom. Provide a growing location with temperatures between 60 and 80 degrees, and a peace plant will flourish as a healthy houseplant.
Fill the growing container approximately three-quarters full of potting soil. Add the peace plant, situating it so that it is at the same depth as it was in the temporary container. Add more soil around the roots of the peace plant and firm the soil down lightly with your hands.
Place the peace plant in a location that receives bright sunlight. Direct sunlight is not necessary; filtered sunlight is suitable. If you do not have a location with bright sunlight, the peace plant will tolerate lower light conditions, but it may not thrive as abundantly.
Fertilize the peace plant once every two to three months. Mix the fertilizer with water, using half of the recommended fertilizer according to the fertilizer package. Pour the mixed fertilizer carefully around the base of the plant without splashing fertilizer onto the foliage.
Allow the soil around the peace lily plant to dry slightly between watering. Do not water so much that the soil becomes soggy and do not let the plant dry to the point of wilting. Fill a watering container with water and allow the water to sit for one day to warm to room temperature and to allow the chlorine present in the water to dissipate. Pour the water into a shallow dish and place the plant container in the dish so that the soil draws the water up into the container from the bottom. Leave the container in the water for one hour and then remove it.
Use the damp cloth to wipe the leaves every few months. This will remove dust from the leaves and may help to keep pests from accumulating underneath the peace plant leaves.
