The Causes of Leaves Turning Yellow on a Peace Lily Plant

Peace lily plants are one of the most popular and easy-to-care-for houseplants you can have in your home. But just like all other plants, a peace lily may have its moments of stress or sickness, causing its usually luscious green leaves to turn a pale yellow and fade.

Knowing what causes this phenomenon to happen is the first step in understanding how to prevent it from happening in the future.

Is Yellow Leaf Discoloration On My Peace Lily Normal?

The short answer is, yes. It’s natural for some of the older leaves on peace lily plants to discolor and yellow over time.

But if there’s a disproportionate amount of yellow leaves with green ones, this usually implies that there’s something wrong with the health of the peace lily plant.

What Causes Yellow Leaves on Peace Lily Plants?

There are several factors that could cause yellow leaves on peace lilies, ranging in severity, from too much water, to too little, from improper potting, to the age of the plant. We’ve outlined some of the most common causes below:

Light Overload

Peace lilies love the sun, and exposure to bright, natural light is essential for them to grow and flower abundantly. But if your peace lily is exposed to too much light for too long, it can cause the leaves to yellow.

This can happen quite quickly if your peace lily is kept in a spot with direct sunlight exposure for hours at a time. Move it to an area that gets more shaded and the yellow leaves should eventually go away.

Inadequate Watering

Peace lilies like a lot of water, but only in the growing season. Insufficient watering can cause the leaves to shrivel and turn yellow due to lack of hydration.

Also, keep in mind that when you water your peace lily, make sure to water it all the way to the base of the plant. Allowing water to accumulate at the base of the plant can also lead to yellow leaves.

Fertilizer Problems

Fertilizing peace lilies is also necessary for the health of the plant. But be sure to use a fertilizer that is specifically made for houseplants. Mix it according to directions, and apply monthly during the growing season.

Too much fertilizer, or an incorrect type of fertilizer can cause the leaves to yellow and burn quickly.

Age of the Peace Lily Plant

Peace lilies are known to produce a new set of leaves every couple of months, and with time, peace lilies can become quite large. As new leaves pop up, the oldest of the leaf still remain, and will eventually start to yellow with age.

When this yellowing become disproportionate, however, make sure to inspect the other causes of yellow leaves on peace lilies.
