How to Care for Peace Lilies Plants

Peace lilies are one of the most common houseplants because they are easy to grow and beautiful! They can be moody at times, but once you know how to care for them properly, peace lilies make a lovely addition to any houseplant collection. Here’s everything you need to know about care for peace lilies at home.

About Peace Lilies

Peace lilies are tropical evergreens that thrive on forest floors, where they receive dappled sunlight and constant moisture and humidity. Mimicking these conditions indoors is key to keeping peace lilies happy and healthy.

In full light, peace lilies produce white to off-white flowers from early summer and bloom year-round in the right conditions.

Most home varieties of peace lilies grow to 16 inches tall, but larger outdoor varieties can grow leaves that are 6 feet tall. Peace lilies are not hardy, so they should only be grown outdoors in warm, humid climates (USDA zones 10, 11).

Are Peace Lilies Plants Poisonous?

Yes, peace lilies is slightly poisonous. All parts of the peace lilies plant contain calcium oxalate—a substance that can cause gastrointestinal irritation if ingested in large amounts. Keep peace lilies out of the reach of children and pets who may be chewing on the plant. Other common plants that contain calcium oxalate are hibiscus, daffodils, true lilies, and hyacinths.

How to Plant, Transplant and Divide Peace Lilies

Use a well-drained all-purpose potting soil. The soil should be able to retain moisture and slowly dry out over time. Peace lilies don’t like to dry out completely, but they also don’t do well if kept in consistently moist soil, as this promotes root rot fungi.

Repotting in spring every few years is good for peace lilies because it likes fresh soil.

Eventually, the peace lily may outgrow its pot, at which point it can be divided. Remove the plants from the pots and divide them into smaller plants, making sure to leave multiple leaves per clump. Peace lilies grow from rhizomes, so they can receive a little harsh treatment during division.

How to Care for Peace Lilies


Ideally, place peace lilies in bright, indirect light. East-facing windows are perfect as the plants will be exposed to the bright morning sun. The north window is also a good choice for peace lily.

Keep peace lilies away from places where they get direct sunlight all day (such as a south-facing window), as this can dry them out too much.


When pouring, consistency is key. Keep the soil slightly moist, but not oversaturated. Peace lilies can tolerate short periods of dry soil, but without enough water or moisture, their leaves will start to develop brown tips.

Tip: One of the wonderful things about peace lilies is that they will tell you when you are thirsty: the leaves of the plant are starting to droop. When the plants start to look less “cheeky” than usual, test the soil with your fingers. When it feels dry, it’s time to water again.

Peace lilies are sensitive to chemicals commonly found in tap water, such as fluoride, which can cause the leaf tips to turn brown. If possible, use filtered water at room temperature.

Peace lilies like high humidity. Spraying the leaves or placing the pot on a damp gravel tray can help increase humidity around the plant.


Peace lilies are not heavy feeders, so fertilize only occasionally. To promote spring and summer growth, start in late winter with a balanced houseplant fertilizer about every 6 weeks.


Peace lilies are tropical plants, so keep them above 16°C and away from cold, drafty windows. They grow best at temperatures above 21°C.

Other care

The large leaves of peace lilies tend to collect a lot of dust indoors. Occasionally dab with a damp paper towel; a thick layer of dust can inhibit photosynthesis.

How to Get a Peace Lilies Bloom

If no flowers appear, the plant is usually not getting enough light. Peace Lilies is very tolerant of low light, but “low light” does not mean no light! To encourage blooming, move the plant to a brighter location that gets at least a few hours of bright indirect light each day.

Improper fertilization can also result in green blooms, weak looking blooms, or a general lack of blooms. For green flowers, reduce fertilization, as plants may be getting too much nitrogen. For weak-looking or lacking shoots, try switching to a fertilizer made for flowering plants. This fertilizer is high in phosphorus, which plants need to bloom.

Yellow leaves can be caused by overwatering, water or (the leaf’s) age. If the oldest leaves are yellowing and the plant hasn’t been replanted in a while, it may just need more room to expand its roots.
