Peace Lily Plant Care

Spathiphyllum wallisii

What is the plant

The Peace Lily Plant, also called Spathiphyllum wallisii, is a great choice for easy indoor plants, with shiny green leaves and unique white spathes. With simple care needs, the Peace Lily does well indoors.

The Peace Lily Plant has beautiful dark green leaves that spread out elegantly from the plant's base. In early summer, you can see pretty white spoon-shaped spathes on the plant, holding a cluster of tiny, true flowers. They typically grow to 1-4 feet (30-120 cm) indoors and up to 6 feet (1.8 m) outdoors in 3 years. Remember, they can be harmful to pets and humans, so be careful where you put them in your home.

How to Care for the Plant

Water
Consistently water your S. wallisii, making sure the soil doesn't get too wet, which can harm the roots. Let the top inch (2.5 cm) of soil dry out before watering, adjusting the frequency based on the pot size and drainage. Water less in winter, but don't let the soil completely dry out. If your tap water has a lot of chlorine, use filtered or distilled water or let tap water sit for a few days to let the chlorine evaporate.
Pruning
You don't need to prune unless you see dead or sick parts that could spread. Pruning can help it grow more, so do it every 6 months or more often if needed.
Fertilizer
Give the plant a bit of balanced houseplant fertilizer every month with micronutrients at half strength in spring and summer. Watch out for yellow leaf edges, which could mean it needs more magnesium and iron. During summer, consider feeding it every week or using slow-release pellets as instructed, but don't fertilize in winter.

Sunlight
Spathiphyllum plants do well in bright, indirect light, but they can also grow in low light. However, they might not bloom well in low light. To avoid problems like brown marks and curled leaves, keep the plant out of direct sunlight. Put it close to an east-facing window for enough filtered light.
Soil
Use a potting mix with peat moss that's similar to the loose soil found in its tropical home. Make sure the mix has enough organic matter and good drainage to avoid too much moisture, which can hurt the plant.
Propagation
You can make more of them by dividing the offsets in early spring when they're growing fast. Do this every 5 years or as needed. Take the plant out of the pot, separate the crowns, or cut a piece of the main root ball, making sure each piece has at least two leaves and roots. Plant them in slightly wet soil, water well, and keep them in a warm, bright place. The roots should grow back in less than a month.

Temperature
Keep the Peace Lily Plant at 65-75°F (18-24°C) all year, protecting it from cold drafts and AC vents. It can't survive for long under 55°F (13°C). To make the best conditions, spray the leaves weekly with softened or distilled water in the summer to make it more humid.
Container
These flowers like slightly crowded conditions, but when their roots outgrow the pot, it's time to replant. Use a terracotta or clay container to handle excess water. Get a pot that's a third bigger than the root ball and not more than 10 inches (25 cm) for healthy growth.
Fun fact
Besides being a symbol of sympathy and peace during hard times, the Peace Lily is also a powerful air purifier, filtering out toxins like formaldehyde, benzene, and carbon monoxide. With its elegant white blooms and air-cleaning abilities, it's a thoughtful gift and a useful addition to any indoor space.
