Why is my peace lily flower turning yellow? As a part of their life cycle peace lily flowers start fading in the last stage and become yellow. It’s a natural, normal process. But there are some other causes for the yellowing of your peace lily flowers. 

Why Is My Peace Lily Flower Turning Yellow

If you don’t solve these causes, then it would be detrimental to the overall health of your peace lily plant. 

Let’s see the reasons and their solution: 

Improper watering: 

Peace lilies prefer to have moist soil but not soggy or dry soil. Overwatering and underwatering both are harmful to peace lilies. 

For example, overwater creates a waterlogged condition in the pot. Roots lead to rot and are affected by other fungal diseases. In this condition, your peace lily can’t absorb oxygen and other important nutrients. As a result your peace lily is drooping, and their flowers turn yellowing. Not only that even your peace lily may turn light green.

On the contrary, allowing the soil to dry out excessively between waterings can stress your plant and result in yellow flowers.


Peace lilies are dramatic, but they are not too thirsty plants. But the right amount of water is necessary for their growth, health, and appearance.  

To avoid overwatering, you should check soil moisture levels before watering. If the top inch of soil feels dry, it means time to water your plants.

While the underwatering issue is also harmful, a good rule of watering is once a week.

Inadequate Sunlight

Peace lilies are adapted to the understory of tropical rainforests with indirect sunlight. They also prefer bright indirect light indoors. If your peace lily receives insufficient light, its flowers often turn yellow color. If you expose your peace lily to direct sunlight, it can scorch and turn yellowing flowers. 


Place your peace lily where it can get enough sunlight to mimic its native habitat.  Ensure your plants are getting bright indirect sunlight. 

Keep away from direct sunlight, as exposure can lead to scorching their leaves and yellowing their flowers. You can consider placing them near a north or east-facing window with sheer curtains. 

Lake of nutrients

A lack of essential nutrients, especially nitrogen, can lead to the yellowing of flowers. Nitrogen can contribute to chlorophyll production, the pigment responsible for the green color in leaves and flowers. When your plants can’t get this vital nutrient, their flowers and leaves start yellowing. 

Additionally, some vital nutrients like phosphorus, potassium, iron, and magnesium are crucial for photosynthesis. Deficiencies of these nutrients weakening your plants and also their floral tissue. 


To solve these problems, it’s crucial to provide your plant with the necessary elements for healthy growth. 

You can fertilize your plant with a balanced, water-soluble fertilizer. Providing organic compost can be a good decision to address their nutrient deficiencies. You also can put the organic waste of your home at the base of the peace lily. 

For example, eggshells can provide calcium, which can play a crucial role in cell wall structure, stability, and the overall health and appearance of your peace lily. 

Lack of temperature and humidity

Your peace lilies need a temperature between 65-80°F (18-27°C) and high humidity to maintain their health and the appearance of leaves and flowers. If your room temperature is unstable, then it can harm your peace lily plants. 

For example, Cold stress and heat stress can cause yellow leaves and flowers. This is because low temperatures damage the plant cells and reduce the water uptake by the roots. 

On the contrary, high temperatures increase the water loss by the leaves. Therefore, your plants become droopy, and their flowers become yellow. 

Moreover, if the air surrounding your peace lilies is too dry with extreme temperatures, then the flowers can turn yellow. 


Try to maintain room temperature between 65-80°F (18-27°C). You can use a thermostat and properly insulate your room so that it can prevent heat loss in colder months and minimize heat gain during warmer months.

To increase humidity levels, you can consider misting the leaves or placing a tray filled with pebbles and water near the plants or using a humidifier. You should avoid placing your plants near close to air vets to avoid cold drafts. 

Diseases or pests

Diseases and pests are also responsible for your yellow flowers on peace lily. Fungal or bacterial infections, such as root rot or leaf spot diseases, can affect the overall health, leading to discoloration of leaves and flowers.

On the other hand, pests like spider mites, that are tiny arachnids, feed on plant sap by piercing the plant cells with their mouthparts. This feeding activity can cause discoloration, stippling, and yellowing of leaves and flowers.


At first you should isolate your affected plant to prevent the problem from spreading to others.

Thoroughly inspect your plants regularly for specific diseases and pests. If found any, deal with insecticidal soap or neem oil to prevent them. 

You can also cut off the yellow flowers so that they can’t spread out. Remember to protect your hand when cutting down the flowers. Because Peace lilies are toxic.
