Brown Peace Lily Tips – Reasons For Peace Lilies Getting Brown

Why Is My Peace Lily Turning Brown?

Peace lily flowers are not only beautiful but they have medicinal benefits too. They contain substances called thymol and salicylic acid which have been used in traditional Chinese medicine (TCM) for centuries. These compounds have proven beneficial to treat various conditions such as cough, fever, bronchitis, asthma, arthritis and many others.

The reason behind the brown tips on your peace lily’s leaves is due to oxidation. Oxidation occurs when certain molecules within the plant cells react with oxygen or other chemicals present in air.

When these reactions occur, they cause the outer layer of the leaf to turn brown. It is believed that there are two main reasons why peace lily leaves turn brown: (1) sunlight and (2) exposure to high temperatures.

Sunlight is one of the major factors responsible for causing browning. Light from the sun causes oxidation in the leaves of plants.

If left unchecked, this oxidation will eventually lead to death. Plants need light to grow and photosynthesis requires energy. Without enough energy, the plant cannot survive and dies. Therefore it makes sense that if you want your peace lily to live longer, you should keep away from direct sunlight during summer months.

There are two other factors to consider when it comes to light: (1) intensity and (2) duration. Intensity refers to the brightness of the light and duration is how long the leaf stays in that brightness.

For example, you can have low intensity light for a longer period of time or higher intensity light for a shorter amount of time. It is best if you can move your peace lily away from bright sunlight, especially in the middle of summer. If this is not possible, you can try to give your plant as much shade as you can.

The second reason why leaves turn brown is due to high temperatures. When the temperature is hot, the enzymes which cause oxidation occur at a faster rate.

This can lead to death if the plant cannot get enough water to keep itself alive. It may seem counterintuitive to move your plant away from sunlight in order to prevent it from dying due to overheating. However, the sunlight is still a major factor. If your plant receives light through a window during the day and no direct sunlight, then it should be okay.

In addition to moving your plant away from sunlight and high temperatures, make sure you are providing proper water. Water helps to keep plants cool during hot weather due to the process of evaporation.

Just like for humans, staying hydrated prevents the body from overheating which can lead to death. Water your plant as often as necessary so that the soil is kept evenly moist.

As the days start to cool and the nights get a little bit cooler, you can move your peace lily back outside or to a warmer location. Just be careful since you don’t want to expose it to freezing temperatures or leave it out during the middle of the day.

Once you know how to care for your peace lily, it should reward you with many years of colorful flowers and antioxidants.
