Peace Lily Flower Turning Brown

Why are My Peace Lily Flowers Turning Brown?

Peace Lily flowers only live about 30 days, with the white bloom lasting only around 10 days.

Your Peace Lily flower turning brown could be a normal occurrence because it might be a sign that your flower has reached the end of its lifespan, causing the flower to wilt and turn brown.

Therefore, it can be quite disappointing when either the green or white flower begins turning brown signaling that your flower is in the process of dying earlier than it should.

If you find your Peace Lily flower is turning brown before the flower’s lifespan has reached its normal end you probably want to know why and look for appropriate solution.

The simple truth is that there could be a number of reasons why your Peace Lily Flower (and even the leaves) may be turning brown.

We will examine some of the problems that can make a peace lily flower turn brown and how to prevent the problem from occurring.

8 Reasons Why Your Peace Lily Flower May Be Turning Brown

Let’s discuss each of the reasons your Peace Lily flower is turning brown and possible solutions.

#1. Direct Sunlight

Peace Lilies need about 6 hours of indirect or dappled sunlight in order to thrive. If you place your plant in direct sunlight the rays from the sun may be too strong and end up stressing or burning the flower.


The solution to this problem is simple. Move your plant to an area that faces an Eastern-facing window (not directly in front) so it gets indirect morning light without being directly in the sun.

#2. The Wrong Temperature

Peace Lilies are tropical plants and therefore need to have higher temperatures in order to remain healthy.

All Peace Lilies need to be in temperatures above 70 degrees Fahrenheit and should never be in a room where the temperatures fall below 60 degrees Fahrenheit.


Place your plant in a room where you can keep the temperature constantly at above 70 degrees Fahrenheit.

#3. Lack of Humidity

The native habitat for the Peace Lily is in tropical climates in the Americas or Southeastern Asia.

The tropics are places of high humidity and the Peace Lily needs to live in a humid environment in order to thrive and for the plant to flower, as it should. Lack of humidity may be the reason why your Peace Lily’s flower is turning brown.


There are several things you can do to increase the amount of humidity for your plant.

You can keep a humidifier in the room that your plant is in. You can also set the potted plant in a tray filled with gravel and water and allow the heat from the room to create humidity, or you can mist your plant during the warmest part of the day.

#4. Fertilizing Too Much or Too Often

Some people are so gung-ho to keep their plants healthy that they tend to fertilize their plant too much or too often.

While fertilizer will help keep your Peace Lily healthy, fertilizing it too often during the blooming process can end up doing more harm than good and may be the reason why your flower is turning brown.


Once the winter has past you should only fertilize your plant once every 6 weeks, from spring through fall.

#5. Watering Your Plant with Tap Water

Many people have a habit of watering their plants with tap water. While this is convenient, it may be another reason why your Peace Lily flower is turning brown. Tap water often has fluorine and other chemicals that may be toxic to your plant.


The simplest way to avoid using tap water is to buy and use filtered water for your plant.

#6. Transplanting Your Plant Too Often

Like many plants your Peace Lily needs to have room to grow. However, if you transplant your plant too often you can cause your plant to stress and even damage the root system.

This can of course, cause your Peace Lily’s flower (and some of the leaves) to begin to wilt and die turning them brown or black.


If your plant comes in a small pot, then transplant your plant once into a pot in the size that will accommodate your plant when it is full-grown.

#7. Stress

Plants can become stressed, which may either result in your plant not flowering or shortening your flower’s lifespan.

Too much or too little sunlight, the wrong water, over fertilizing, fluctuations in temperatures, and lack of humidity can all cause stress to your plant. In addition, inconsistent times of caring for your plant can also result in stress to your plant.


Following the plants care instructions to the letter and making sure you water your plant at the same time every day can help reduce the stress to the plant and help to keep it healthy.

#8. Age

Peace Lilies do not live forever, nor do the flowers on a healthy plant. Your Peace Lily flower goes through a life cycle.

As the flower forms, the spadix is green, then it turns to white for about 10 days turning green again during pollination. As the old plant dies the flower slowly turns brown.


There really isn’t anything you can do to prevent your flower or the plant itself from aging. However, with proper care your flower should last for its entire lifespan.

How To Remove Dead Flowers from Your Peace Lily

Once your Peace Lily flower turns brown, it is best to simply prune the flower. In order to properly prune the flower, you need a clean pair of pruning shears. Prune the stem of the flower at the base of the plant. At this time, you should also prune any leaves that have turned brown.

Can You Make Peace Lily Flower Last Longer
