How to Care for Peace Lilies (Spathiphyllum)

Rate this Article:

Peace lilies are one of the most common houseplants because they are so easy to grow. Here’s everything you need to know about caring for a peace lily in your home!

About Peace Lilies

Peace lilies are tropical, evergreen plants that thrive on the forest floor, where they receive dappled sunlight and consistent moisture. Replicating these conditions in the home is the key to getting your peace lily to be happy and healthy.

With enough light, peace lilies may produce white to off-white flowers in the early summer and continue to bloom throughout the year.

Most household varieties of peace lily grow up to 16 inches tall, but larger cultivars can reach 6 feet in height. Peace lilies are not cold-hardy plants, so they may only be grown outdoors in warm, humid climates.

Is the Peace Lily Plant Poisonous?

Yes. All parts of the peace lily plant contain calcium oxalate—a substance that may cause stomach and respiratory irritation if ingested in large amounts. Keep peace lilies out of reach of small children and pets. Other common plants that contain calcium oxalate include daffodils, true lilies, and hyacinths.

Planting

How to Plant, Transplant, and Divide Peace Lilies

Use a well-draining, all-purpose potting soil.
Repotting annually in the spring is good for the peace lily, as the plant will appreciate the refreshed soil.
Eventually, the peace lily may grow too large for its pot, at which point it can be divided. Remove the plant from its pot and split it into smaller plants, being sure to leave several leaves per clump. The peace lily grows from rhizomes, so it can tolerate a bit of tough treatment during dividing.

Can Peace Lilies be Grown in Water?

Yes, peace lilies can be grown in water—they are often sold in vases without any soil. Ideally, the base of the plant should be suspended above the water line, either by a specially-made insert or a layer of small stones. This allows the roots to grow into the water, but keeps the base of the plant and its leaves from being too wet.

Care

How to Care for a Peace Lily

Keep the soil moist, but do not overwater. Peace lilies can tolerate short periods of dry soil, but their leaves will start to brown if neglected for too long.
Peace lilies are sensitive to chemicals commonly found in tap water, such as flouride, which may cause brown leaf tips. Use filtered, room temperature water, if possible.
Peace lilies enjoy high humidity. Misting their leaves or placing their pot atop a moistened tray of gravel can help to increase humidity.
Peace lilies are not heavy feeders, so fertilize only occasionally. To encourage spring and summer growth, fertilize every 6 weeks or so with a balanced houseplant fertilizer starting in late winter.
Peace lilies are a tropical plant, so keep them in temperatures above 60°F (16°C) and away from cold, drafty windows. They do best in temperatures upwards of 70°F (21°C).
Keep these plants out of direct afternoon sunlight, but in a well-lit area. An east- or west-facing window is ideal.

How to Get Peace Lilies to Flower

Most often, if no flowers are appearing, the plant is not getting enough light. Peace lilies are very tolerant of low light, but low light does not mean no light! To encourage flowering, move the plant to a brighter location, where it will receive bright, indirect light.
Green flowers, weak-looking flowers, or a general lack of flowers can be caused by improper fertilizing. In the case of green flowers, cut back on fertilizing. In the case of weak-looking flowers or a lack of flowers, try switching to a fertilizer made for flowering plants. This type of fertilizer will have a higher amount of phosphorous, which plants need for blooming.

Pests/Diseases

Brown leaf tips are commonly caused by excessive light, over-fertilization, or lack of water and/or low humidity. Keeping the plant on a tray of moistened gravel or misting the leaves can help to increase humidity.
Yellow leaves may be caused by overwatering, underwatering, or old age (of the leaf).
Scale and mealybugs will happily take up residence on the plant, if given the opportunity. A thorough wipe-down of leaves with soapy water or insecticidal soap can be effective at stopping them.

Recommended Varieties

Spathiphyllum wallisii is a smaller peace lily, reaching only 12 inches tall. ‘Petite’ is smaller still, at approximately 8–10 inches.
‘Sensation’ is the largest variety available, often growing up to 4–6 feet in height and width.
‘Domino’, which has attractively variegated leaves, and ‘Mojo Lime’, which produces lime-green foliage, are two medium-size cultivars.

Wit & Wisdom

In NASA studies, it was discovered that peace lilies can help improve air quality, removing formaldehyde, benzene, and carbon monoxide from the surrounding air. Read more about air-purifying houseplants!
The peace lily is said to have gotten its common name from its white flowers, which rise timidly above its green foliage and resemble small, white flags of peace.
Despite the peace lily’s common name, it is not related to true lilies at all.
The plant’s interesting blooms are also the source of its Latin name, Spathiphyllum, meaning “spathe-leaf.” The flowers consist of the spathe (the white, sheath-like leaf) and the spadix (the spike of small flowers located within the spathe).

peace lily plant

peace lily flower

I recently received a peace lily as a gift. So far it seems to be doing OK. There are many white droppings on a leaf under one particular flower and only that one. Is this normal or should I be concerned?

peace lilies and bugs

It’s possible this is a small bug. Clean your peace lily with a forceful water spray. Washing the plant’s leaves with soapy water and rinse off. Use a cotton swap to wipe off any droppings.

Thank you.

Peach lily flower

I got my Peach Lily plant about a year or two. They recently bloomed, but the flower are really small compare to when I first got the plant. Can you please help me?

Small peace plant flowers

Plants that are grown and prepared for commercial sale (just about any store) are pampered with TLC to put on (often) their best-ever show. It can be difficult to keep up those appearances in a home environment. The temperature, the humidity, the light, the water, the love…are not the same. Your plant may never produce at home like it did in the nursery. But read below: at least it is flowering; many do not. Keep doing what you’re doing. (Speaking from experience. I have a peace lily on my desk and it is a shadow of it’s former self. But it’s still upright.) Good luck!

Peace Lily

My peace lilies bloomed about twice since I got them several years ago. They are in an area where they seem to receive sufficient filtered light and I keep them watered. However, they DO NOT bloom!! Both have healthy, dark green leaves and look good, but NO blooms. Disappointing.

Give peace a chance

Peace lilies are challenging plants. Your plant may seem to get sufficient light… but it might not be the right amount or the right light. See the care tips above.

And how’s the room temp? They like it warm. See above.

Finally, consider this advice from another visitor to this page: While peace lily’s don’t need a large amount of light they still need some especially if you want them to bloom. Depending on where you live dry air might also be a contributor. Misting your Peace Lily every few days and keeping it away from any vents would probably be a good idea as the air flow from the vent will dry the air and plant out faster and misting will put more moisture into the air.

helpful information

I just wanted to say thanks. The information was very helpful in assisting me with how to care for my houseplants.

The roots are coming up from the dirt at the top of my plant

I love my peace lily plant and I would like it to live a lot longer concerned if my pot is too small it's a pretty large Plant please help

planting peace lily

Can I plant my small peace lily into a large or very large container?

Repotting Peace Lily

Generally, it is not recommended to repot plants in pots that are too large, as the large amount of soil can hinder the roots’ ability to suck up enough water.

repotting peace lily

How do you know what size is to large? I have mine is a pot about 10 ins round about 12 ins deep. It needs a bigger pot. I have a pot that is about 12 ins on bottom but top of pot is about 20 ins around. Please help. Thank you

Repotting Peace Lily

With a peace lily, never make a big jump in pot sizes. Don’t jump more than two inches larger in diameter than the previous pot. Peace lilies like being a little root-bound.

No flowers on my peace Lilly. Help!

I have had this for a few years and it does not re-flower. I have it placed in a window where it receives filtered sunlight daily. I water it every Saturday and the green foliage looks wonderful. But it has never rebooted. What Can I do?
Thank you for your suggestions.

No blooms

I had the same problem until I started using my used tea bags as fertilizer. Now I have 5 blooms on the plant that had not bloomed again after the initial blooms died.

Stressed peace lilly

I bought a fairly large peace lilly a couple of months ago, I knew it was too large for the pot it was in so I transplanted it to a much larger pot, after doing so, as plants do, it stressed out. I trimmed all the dead leaves but after about 6 weeks none of the other leaves are standing up, they are all bent over but alive. Would tieing them to a stake help them recover? I can see the bend in each stem and the leaves are way to large and heavy for the stem to stand back up on its own. As I said its alive and kicking but not attractive at all because NONE of the leaves are standing up they are all dropping over the sides of the pot. I have wooden kaboob skewers and I used a garbage bag twist tie to on one of the biggest stems just the other day, do you think that will help?

Stressed peace Lilly

Too much water in the pot or too little can do that. I had the same thing happen when my Lillie’s were left outside in the summer (not in direct sunlight). I brought them home and watered them, sprayed the leaves with water and in 2 days they came back to life! Hope that helps.

Peace lily soil

Can you mix cow manure and topsoil to an organic potting soil mix for the peace lily.

Soil for Peace Lily

Hi Andre,

For an indoor potting mix, topsoil is not a good mix. It can lack many nutrients that the plant requires. For cow manure, it should be well aged for at least 6 months before being used. Mixing the manure with the organic potting soil mix will work just fine.

Watering

How do you know how much water is to much for the Peace Lily plant in terms of amount. in other words if you should water according to the size of the pot,amount of dirt, etc.? Can over watering occur even if there is no excessive water drainage?

Flower

I bought two and got both of them to flower. Will the flower die after awhile or will it stay ? If it does die will the same plant produce another flower ?

Spath Flowers

The flower will die after a few weeks or so but the plant will produce more.

Wilting Peacelilly

I have a small peace lilly which i bought 3-4 months back. I keep it in my room which is moderately warm but without any sunlight, I often turn on AC through out night. For the past 1 month the plant has lost all its flowers, and the tips are turning brown. I give water thrice a week but its getting lighter and there is absolutely no growth. Unable to add picture in comment otherwise would have showed the current condition. Advice please! p.s. the plant was a present and i really dont want to lose it :(

Wilting Peace Lily

While peace lily's don't need a large amount of light they still need some especially if you want them to bloom. Depending on where you live dry air might also be a contributor. Misting your Peace Lily every few days and keeping it away from any vents would probably be a good idea as the air flow from the vent will dry the air and plant out faster and misting will put more moisture into the air.

How much water for my peace lily?

Hi there. I just got my first peace lily plant. I was told to water it every 3-4 days. About how much water should I be giving it? It's a medium sized floor plant. I read some of the comments and noticed it looks like the leaves are slightly wilting and the soil is dry, so wondering if I haven't given it enough water. Thanks for your help!

Leaves

I was given a peace lily by my late mother-in-law so I want to keep it. She always kept it indoor as it is extremely large. I have put it on my front porch, hidden from direct sun but some of the leaves seem to be losing their green color. The new growth(not all) is slightly a lighter green. Does it need more sun? I have another Peace lily that gets more sun and no problem.

Light Green Leaves

New growth is often a lighter shade of green than old growth, so that itself is not concerning. However, you also state that some of the old leaves are losing color, too. Are they turning yellow or white? This could be caused by a few factors: primarily temperature, nutrients, humidity, and light. Temperatures below 60° F or above 90° F can cause problems, so take the plant inside if you expect extremes. Nutrient deficiencies can also cause leaf discoloration, so you may try feeding the plant with a bit of houseplant fertilizer. Low humidity can also cause yellowing. Finally, discoloration can occur when the plant is exposed to too much light. Peace lilies prefer bright, filtered light, so if your plant isn’t getting that now, try moving it to a better location.

Peace Lily plant

I have 4 long 2 to 4 ft. trailing stems on my peace plant and wonder if I should allow them to grow or cut them off?
