How to Care for a Peace Plant


The peace lily, an attractive plant with dark green foliage and showy white flowers, is one of the few plants that will flower in low light. Not only does a peace lily plant add beauty to your home, it improves air quality. In a clean air study, Spathiphyllums were found to be among the top 10 plants for removing pollutants from the air, the University of North Dakota Extension notes. Care for a peace lily plant by providing the proper temperature and moisture.

Step 1

Place the peace lily plant where the temperature ranges from 68 and 85 degrees F during the day and about ten degrees cooler at night.

Step 2

Keep the peace lily away from direct sunlight. Though it is known for its ability to thrive in dimly lit settings, it does best in bright, filtered light.

Step 3

Fill a tray with pebbles and a small amount of water and place the plant nearby to provide it with added humidity. Or, consider keeping the peace lily in the bathroom to achieve a similar effect.

Step 4

Water the peace lily regularly to keep the soil moist at all times. Select a pot for the peace lily that contains holes in the bottom to allow excess water to drain out. Dump out any water that drains into the saucer after watering to avoid root rot. Use bottled drinking water or rainwater to avoid salt build up in the soil.

Step 5

Fertilize the peace llily during active growth. Feed the plant approximately once a month with a standard fertilizer mix, using about a quarter of the recommended amount. Peace lily leaves can burn with excess fertilization, cautions the University of North Dakota Extension.

Step 6

Wipe leaves clean regularly with a damp cloth to remove any dust and keep them shiny, or give them a shower every other week.

Step 7

If mealy bugs appear on a peace lily, treat the plant with an insecticidal soap following manufacturer's directions.

Step 8

Re-pot a peace lily every year or two with a mixture of equal parts peat moss, loam, and sand.
