Do your peace lily yellow leaves start to make your plant look sick? Several reasons can cause yellow leaves in your plant.

Top 8 Reasons for Peace Lily Yellow Leaves

Overwatering Peace Lilies 

Overwatering peace lilies is one of the biggest reasons the leaves turn yellow. Unfortunately, it is a common problem with most indoor plants. When there is too much wetness near the roots, it deprives them of oxygen delivery and can lead to root rot.

We recommend checking the soil between watering to feel if the top inch is dry. Another concern is to check if the container has a well-draining mix with enough drainage holes. Finally, when you water your plant, make sure that the water drains freely and remove the excess water.

Lack of Fertilizer 

Your indoor peace lily can thrive without too much feeding as they need some nutrition for surviving. But when these tropical plants start showing leaf yellowing, it can be a lack of nitrogen.

Another cause can result in the lack of iron or magnesium that is easier to spot. The leaves turn yellow with the latter’s absence, but the veins remain green.

Natural Aging

A natural process is the aging of your lily, and the leaves start turning yellow or brown eventually, it dies. When you notice the lower leaves turning yellow, you can remove them using your pruning shears.

While the peace lily is not sensitive, plants to drought underwatering them can also lead to leaves wilting and turning yellow. This is because your plant needs regular watering and depriving them of water causes the leaves to fall off.

Too Much Light

Peace lilies thrive in shaded areas, and they flourish in low to medium light for producing those gorgeous blooms. Yet, when your plant stands in too much direct sunlight, the leaves turn yellow, with the veins remaining green.

Too Little Light

Peace lilies thrive in shaded areas on the forest floor in their natural habitat and can stand in a dim corner with some filtered sunlight. But when they do not get enough light, they do not produce blooms. Furthermore, it can result in the lily leaves turning yellow.

Temperature and Humidity

Peace lily leaves turning yellow can also result from a draft or extreme temperature change. Your plant flourishes in temperatures between 65°-85° Fahrenheit. When temperatures drop below this, it starts causing damage.

When temperatures drop, you can place your plant outdoors in warmer months and bring them inside. Always put your peace lily indoors in a spot free of cold drafts.


Your peace lilies do not need repotting often, but it still needs space to grow with enough nutrients in the ground to flourish. So, when the time comes to transplant, your lily transplant shock can cause yellowing leaves. Yet, if the lily has a healthy root system, it should handle transplanting well.

The best time to repot is in spring before the growing season. Then, when you detect yellow leaves, you can remove them.

Taking Care of Your Peace Lily
