Peace Lily Plant Care Guide

Peace Lily Plant Care Guide

Finding a beautiful houseplant to take care of can be a tricky process. Fortunately, the Peace Lily plant has been well-loved among gardeners for its easy keeping. In fact, most Spathiphyllum, or tropical flowering plants, are chosen for their fragrance and ornamental display.

Spathiphyllum is a genus of 47 different species of flowering plants in the Araceae family. Some plants that belong to the same family are Monstera Adansonii, Monstera Deliciosa and Philodendron hederaceum. The are all considered to be Aroids. A telltale of an aroid plant are that they are flowering plants and produce a spathe and spadix.

Where is the natural habitat of the Peace Lily?

The Peace Lily plant is native to the tropical rainforests of South America, mainly around Columbia and Venezuela. They are known for their iconic white “flowers”, which are actually spathes. Paired amongst the dark green leaves, these plants make for a great addition.


Peace Lily Care

Keep Peace Lily in slightly moist soil high in organic matter that is well-draining. Spathiphyllum grows best in bright indirect light but can tolerate lower light conditions. The ideal temperature range is 65 to 80 °F (18 and 26 °C). Peace Lily does not tolerate temperatures below 45 °F (7 °C). They can be grown outdoors in USDA zones 10-12. Humidity should be above 50%, 60%, and above is ideal. Fertilize every 6 weeks during spring and summer with a balanced liquid fertilizer at half strength.


Spathiphyllum individuals are relatively easy to take care of, especially indoors. 

In this article, we will look at the various needs of this plant so that you can have a thriving Spathiphyllum for guests to gaze at.



To keep a plant happy and healthy, there must be a number of requirements met. Here are the care preferences for the Peace Lily houseplant.



Spathiphyllum plants can live for a short period of time when placed in dry soil, though this isn’t the most conducive setting.

These plants are happiest in soil rich in organic matter that is always somewhat damp.

As long as it drains properly, a simple potting soil will do, as they have no particular demand for a certain type of soil.



The Peace Lily plant does not require a great deal of light to survive. For the best results, it is ideal to place your Spathiphyllum in a room with bright indirect light.

If you do not have a spot for this with such needs met, you can even grow them with inflorescent lighting.



To ensure that the roots support your Peace Lily, you’ll want to keep your plant watered.

The top inch of soil should be consistently moistened for a happier Spathiphyllum.

Without slightly moist or overly moist soggy soil, leaves can start to yellow and the spathe won’t develop as profoundly.

Peace Lilies are will get dramatic if underwater. They will droop quite a bit up to the point where you might think your indoor plant is a lost cause.

But let me tell you. More often than not I managed to resurrect my Peace Lily with a good drink. 

This is not the plant to underwater or forget watering. This Lily will clearly let you know that it is unhappy.

The best water to use for a Peace Lily is either rainwater, reverse osmosis water, or distilled water.

My Peace Lily often gets brown tips from tap water because of the salt build-ups and the chlorine.



Like most houseplants, this plant does not like a sudden change in temperature or a cold draft.

They are happiest when kept in a room that stays between  65 to 80 °F (18 and 26 °C ).

These plants do not tend to survive temperatures lower than 45 °F (7 °C).

Peace lily can be grown outdoors in USDA hardiness zones 10-12.



The Peace Lily is a tropical plant, coexisting in South American rainforests.

Based on this information, it isn’t hard to tell that these individuals prefer a good amount of humidity.

A humidity level above 60% is best but they will tolerate anything about 50% humidity without a problem.

Many Spathiphyllum owners keep them moist with the use of daily misting and humidifiers.



Although not entirely necessary, this type of plant can benefit from having the occasional plant food.

Opting for a fertilizer that is balanced and a dilute it to half strength is the best strategy.

The typical water-soluble houseplant fertilizer will work. Apply every 6 weeks during the main growing season in Spring and Summer.



To ensure that your plant grows successfully, it will need to be propagated every once in a while.

The most straightforward method of propagation for the Peace Lily is through division.



The typical home-dwelling Peace Lily will grow to a height of  16 feet  (40 centimeters), while outside cultivars reach around 6 feet (182 centimeters).

This heavily depends on the type of Peace Lily as there are dwarf variants and others that grow much bigger.



When met with the proper requirements, this species of Spathiphyllum blooms in Spring and might flower again in Autumn under ideal conditions.

The blooms last for 2 months and the white part of the flower is a modified flower and called a spathe. The spadix is the “yellow” part and consists of the actual flowers. 

Peace Lilies are aroid plants belonging to the Aracaea genus of flowering plants. All aroids produce a spathe and a spadix.



Removing your Peace Lily from its original pot once it has outgrown it is paramount for a happy plant. You will have to repot your Peace Lily frequently.

You can expect to need to do this every year, preferably in the spring as this Lily is a vigorous grower.



Knowing the difference between too little and too much water is a challenge all plant owners must face.

Understanding how to water your Peace Lily properly will save the leaves from wilting. Given their original habitat, this Spathiphyllum requires a somewhat large amount of water.

To save you and your plant from over- or underwatering, let’s look at a few key points.



This plant can survive when presented with a short drought, but that is far from ideal. Instead, you must try to consistently keep the soil moist.

Simply achieve this by watering the entire plant until the water can be seen exiting any drainage holes. These plants do not like to sit in the water where their roots can become soggy.



The first rule of thumb with watering a Peace Lily is to take note of the top inch of soil. If it is dry, give your plant a fair amount of water until it drains out the bottom.

Another indicator can be shown in the plant themselves. One of the easiest ways to identify a lack of water is to observe any flopping behavior. Watering will set them right again.

Expect to thoroughly water your Peace Lily once a week, more during the summer growing season.

A commonly discussed way to water your Spathiphyllum is by placing it in the sink. Continue to pour the water slowly into the soil.

Once you’ve noticed that the water escapes through the bottom of the pot, you’ve given it enough water. First, let your plant entirely drain before returning it back to its original location.



These individuals are particular in what type of water is used. Surprisingly, the Peace Lily is more sensitive to chemicals than other plants.

These chemicals include common tap water ingredients such as Fluoride. The best water to use is filtered water that is around room temperature.

You do not want to let your plant become too dry. And unfiltered water may cause browning of the leaf tips.

Finding that balance between the right amount of water and the correct water quality can make quite the impact. As stated above, providing your Spathiphyllum with the proper drainage is pivotal.



Not every plant owner is comfortable with the idea of propagation. This activity is necessary, however, allowing the plant to continue living in a clone.

Even if you’re new to propagation, the Peace Lily is rather straightforward. The simplest way to propagate this houseplant is through division.

Once old enough, these individuals start to develop a rhizome. These rhizomes are stems that grow horizontal to the soil’s surface. This is where you can prepare yourself for propagation.

The following steps are provided to ensure that you correctly propagate your Peace Lily in order to reap the rewards of showy white spathes.


Step 1: Though not entirely important, the easiest and the best time to propagate a Peace Lily is after it blooms. This way you avoid risking a less than ideal blossom.

Step 2: Find the rhizome underneath the soil by either gently using your hands or a piece of silverware. Once you’ve identified the desired rhizome, take the plant completely from the pot and rinse away any excess wood.

Step 3: Take the newly discovered rhizomes and cut them into sharp pieces. This can be done with the use of a knife or pruning shears. Make sure that each rhizome has an associated bud or growth point.

Step 4: Use a container to store your new rhizome divisions in a potting soil mix that is of high quality. These divisions should roughly be the same size as the original Peace Lily while in the container.

Step 5: Water your new division, until there is water leaking out from the bottom. Once completed with watering, put them in a spot with indirect lighting.

Step 6: Be sure to check whether or not there are more people on the list. The soil should be moist, not soggy.

Step 7: Check on your newly divided Peace Lily plant, transferring it to a new pot when it grows too big for the current living situation.



As far as houseplants go, the Peace Lily is pretty easy to keep happy. This does not mean, however, that there won’t be problems later down the road.

Realizing the more commonly found issues is a great preventative measure.

The following paragraphs discuss the problems you may find in a Peace Lily plant, the cause of the potential hazard, and a remedy to help make your individual healthy again.


A healthy Peace Lily leaf has a dark green colour

A healthy Peace Lily leaf has a dark green colour.



Cause: The yellow coloration that you may find in a Peace Lily can be a result of a number of different issues.

The most common reason for yellow leaves on a Peace Lily is that the individual has been overwatered.

Do keep in mind that these plants tend to yellow with age, so it might be related to seniority.

Remedy: If you notice the leaves shift from dark green to a light yellow color, the first course of action should be letting the plant breathe when it comes to watering.

Allow your Peace Lily to dry out completely and then adjust your watering schedule as needed.



Cause: The likelihood of your plant showing little to no progress in terms of producing blooms can be tied to the amount of sunlight.

These plants are somewhat picky when it comes to light requirements, meaning that you can simply move them around the house until you find the right remedy.

Remedy: Given the fact that blooms are related to light exposure, you’ll want to move your Peace Lily to an area with indirect light.

They still need bright sunlight, yet it should not be directly in a window where damage can be sustained.



Cause: Another problem that may exist is when the edges of the leaves on a Peace Lily turn brown. The cause for this is once again related to the amount of light exposure. It may also be a result of inadequate humidity.

Remedy: The browning of the leaf edges can be linked-to light or humidity requirements.

To pinpoint the problem, you’ll want to tackle one issue at a time.

First, see if your plant starts to heal when moved to an area of the house that is out of direct sunlight.

If that doesn’t work, increase the humidity. The easiest way to accomplish this is to increase daily misting.



We hope that this guide increases your confidence when it comes to raising a happy and thriving Peace Lily plant.

Being able to display a tropical houseplant with a striking white spathe is worth the effort, even if the Peace Lily isn’t all too strenuous.

To make things simple, we’ve combined a few of the most important takeaways that will keep a Peace Lily plant thriving and blooming.

1. Be careful not to overwater your plant. They do not like to be in soil that is either drenched or too dry. Add water whenever your plant becomes “saggy”, or if the top inch of soil is dried out.

2. When watering your Peace Lily, do so with filtered water that is kept at room temperature. This is due to their high sensitivity when it comes to chemicals.

3. In order to keep your plant beautiful and blooming, place it in bright indirect sunlight.

4. Take note of the temperature, making sure to not have your Peace Lily in a room that drops below 7 °C. The ideal range for these individuals is between 18 and 26 °C.

5. Identify a semi-consistent feeding schedule for your Spathiphyllum. They do not need a lot of fertilizer, averaging about every 6 weeks.

With all of these tips and tricks, surely you’ll have a happy houseplant. Even with all of this new knowledge, you may still be a little unsure about the care of a Peace Lily. Any unanswered questions hopefully can be addressed below to help you with that.


Toxicity of the Peace Lily

The Peace Lily is toxic to dogs and also toxic to cats according to the Animal Poison Control Center ASCPA.

Please do not believe the information on the internet claiming that these plants are not toxic as this could have negative consequences.

Peace Lilies contain insoluble calcium oxalates or sharp crystals that lead to oral irritation burning and also irritation to the mouth, lips, and tongue.

Furthermore, intake can lead to vomiting, difficulties in swallowing as well as drooling. 

Its juices can also irritate the skin and cause burning and swelling. Peace lilies are also toxic to humans.

Make therefore sure that neither animals nor children are getting in contact with the Peace Lily and avoid any intake. 

The Peace Lily is therefore not on our list of cat save houseplants.
