The peace lily is one of the few houseplants that will grow and thrive in very low-light situations. It's large, deep green leaves are offset by their bright white flowers that resemble calla lilies. It readily reflowers under normal household conditions and seems to tolerate neglect quite well. If you have a dark corner that needs to be brightened, fill it up with a peace lily, which will grow and thrive there.
Grow your peace lily in a spot that receives indirect light but no direct sunlight. These houseplants can grow and thrive even if they are placed 8 to 10 feet from a window.
Provide high humidity for your peace lily. Mist several times a day or run a humidifier in the room where it grows. Another way to increase humidity is to put it on a saucer filled with pebbles and water up to just under the tops of the pebbles. As the water in the saucer evaporates it adds its humidity to the air around the plant.
Water when the soil feels dry an inch below the surface. Do not over water or the tips of the leaves will turn brown.
Fertilize every two weeks during the spring and summer active growth period. Use water-soluble houseplant food mixed at one-fourth the rate recommended by the manufacturer. Apply the fertilizer solution to the soil of your peace lily the day after you have given it a thorough watering.
Transplant every two to three years and then only if the roots are obviously crowded in the pot. Do not transplant into a much larger pot; transplant into a pot that is only 1 to 2 inches larger than the one in which it is currently growing.
Remove flowers when they begin to fade. Cut the stem of the flower as far down into the crown of the plant as you can without damaging the adjacent leaves.
