Causes and Solutions for Peace Lily Leaves Turning Yellow

Peace lilies typically don’t require much attention and seldom have problems if they are watered once or twice a week. Although the leaves on your peace lily may turn yellow, this is not usually an indication of something wrong with the plant itself. The leaves on your peace lily are typically more prone to turn yellow and dry out when the weather is hot.

The peace lily is a hardy perennial herbaceous plant with leaves and stems usually covered in the fulcrum, the minute leaves, and stems of the herbaceous. The leaves are usually 2-4 inches long and sharply pointed at the apex. In addition, the foliage of your peace lily plant is oval and yellow, with a striking pattern on the leaf that is reminiscent of an eagle’s head.

This article will explain why and how your peace lily’s leaves may be turning yellow, as well as give you some tips and advice on how to handle this problem without harming your peace lily.

1. Aging Leaves:

Sometimes, the leaves of a plant will begin to yellow, even though they are not wilted. The leaves of your peace lily will begin to yellow at about the same time as its flowering period begins, usually in early September. The situation is perfectly normal and does not mean the plant is sick.

If you notice that your peace lily’s leaves are turning yellow more than usual, you might want to cut them off and start them in a new potting soil mixture made from equal parts of sphagnum peat moss perlite and vermiculite. You should water the new pots well and ensure no dirt particles remain in the bottom. Place the pots in a bright, sunny location.

2. Too Much Water:

Peace lilies are excellent plants for indoor decor and can even be placed in outdoor gardens during summer. Although peace lilies can also go for about three weeks without water, they need to be watered more frequently if you want your plant to be healthy and flowering. Over-watering is a common problem if you live in an area with heat, humidity, and poor air circulation. The leaves of an over-watered peace lily will begin to yellow, eventually turning brown and dying altogether. Trapped water beneath the leaves causes rot, as well as bacteria growth.

If your peace lily has green leaves that are turning yellow on the edges only, it may just need more sunlight or humid conditions. In this case, you may want to relocate your peace lily to a more sunny location temporarily.

3. Under watering:

A less common reason for yellowing leaves is actually because of under watering. While peace lilies need water, they can also tolerate a long period without it. under watering causes stress on the leaves, causing them to flop over and become discolored. The plant will eventually die if you continue to under-water your plant.

If you notice that your peace lily has brown leaves beginning to droop or turn yellow, it may be time to water the plant. However, be sure not to overwater plants with yellowing leaves; if the roots sit in water for too long, they begin to rot and cause all of the plants’ problems.

4. Disease:

If none of the above causes are correct, the plant itself may be a problem. Peace lilies often occur together in the same neighborhood and are often found in gardens with other poisonous plants such as poinsettia, multiflora rose, and geranium. These plants can cause similar problems to your peace lily, including yellowing leaves or wilting. Symptoms of these diseases include brown spots on leaves, wilting, and stems that begin to dry out.

The best way to avoid replacing your peace lily each year is to choose a healthy plant from a reputable nursery, which will mean more peace lilies for you.

5. Too Much or Too Little Light:

The peace lily is a plant that prefers medium light and should be placed in an area with plenty of sunlight or shade. However, if you have too much light, the foliage of your peace lily will begin to turn yellow due to photosynthesis. If it is too dark, you may notice that the foliage will begin to turn brown and die.

If your peace lily has been in the same location for a while, move it to a new place with more sunlight. Be sure to keep it in an area with good air circulation and ventilation by opening windows or bringing in fans or other sources of fresh air to prevent fungus from developing on your soil or leaves.

6. Insect Infestation:

The major pests of peace lilies are aphids and thrips. Both pests are difficult to detect because they are small and hidden among the plant’s foliage. Aphids are small, pear-shaped insects that suck the juice out of your peace lily and spread the fungus. Thrips are tiny, black, or brown-colored bugs that cause the same damage as aphids.

The best way to get rid of aphids or thrips is to take a paper towel and dab them off your plant’s leaves. You may also spray your plant with insecticidal soap, a safe product for houseplants. However, if you notice any sap on the leaves, you’ll want to wash your plant thoroughly with water before using any insecticides.

7. Water Quality Issues:

Not all water is healthy for peace lilies. Tap water can harm the plant by leaving behind a mineral deposit on the leaves and stems that can eventually cause them to turn brown and die. If your peace lily is healthy, it can survive for a few weeks without watering but will begin to die if not watered regularly. In most cases, peace lilies thrive on rainwater.

If you have hard water or not enough rain, you may consider a water filter or bottled distilled water that doesn’t contain limestone or rust particles that might damage the leaves of your plant.

8. Nutrient Deficiency:

Nutrients are necessary for the health of your peace lily. Nutrients include minerals and vitamins, such as boron, iron, zinc, and manganese. A lack of any one or a combination of these nutrients may cause leaves to begin turning yellow. The leaves will also turn brown and begin to die.

To correct this deficiency, you should report your plant into a new soil mixture of equal parts sphagnum peat moss and perlite or vermiculite. Water, the pot well until water drains out the bottom. Place the pot in a bright area with good ventilation and keep it watered regularly by ensuring that water drains out at the bottom after watering and that there is no standing water remaining on top of the soil mix.

9. Temperature:

Another problem you might notice when growing Peace lilies is that they are not growing as fast as they should. Although these plants enjoy warm temperatures, they require a cool period for normal growth.

If temperatures remain between about 70-75 degrees Fahrenheit for about two weeks or longer, your peace lily will begin to grow more slowly than usual because it’s in a resting period. After resting, the plant should be fine and resume its normal growth. If your peace lily has been exposed to high temperatures for an extended period, it may begin to show signs of stress. Leaves may turn yellow or brown and begin to fall off altogether. The leaves sometimes begin curling up or falling off while their stems remain green.

Potted plants should be kept away from hot sunny windows and instead moved to a light location that gives the plant sufficient sunlight while preventing it from getting too warm.

If possible, you should move the pot outside on cool nights so the plant can absorb cooler temperatures during its rest period. If your pot is in danger of freezing for any time during this period, water it so that the soil stays slightly moist.

10. Transplant Shock:

When moving your peace lily, it’s best to move it gradually. If you’re moving it from one location to another, start by moving it several feet away from its original location. Water well and leave it in the new location for up to a week before moving it again.

If you’re transplanting your peace lily, dig a hole about twice as wide as the pot is and about twice as deep. Move the plant into this hole and fill it in around the plant with soil from the hole. Water well so that water runs out of the bottom of the hole after watering, or else water will pool in shallow areas or on top of the soil instead of soaking into roots.

During the transplanting process, be careful not to disturb roots close to the surface of the soil. If the roots are disturbed, they will break off or fall out, and the plant may die or become sickly.

How to grow the plant:

The peace lily is a very easy plant to grow and propagates readily in spring. Maintain them in bright, indirect light and keep the soil moist but not soaked. Cut off the foliage after it has spent its blooming life-usually after two or three years. Peace lilies will survive a single-digit winter in a cold frame if planted in early fall. In many parts of the country, it is best to plant the peace lily in the fall where it can survive winters outdoors. If you live in an area with hot summers, you may have to move your peace lily to a cooler location for a few months during the summer if you don’t have air conditioning. Water your peace lily only when the leaves start to wither.


Propagating your peace lily is simple when your know how. You can divide the plant’s rooted crown or grow new stems from its rhizomes (underground stems). The rhizomes grow at a wide variety of depths and must be located and pulled up after a few weeks.


You should report your peace lily to keep it growing vigorously. Re-pot using fresh soil and repot every 2-3 years.


Mealybugs and aphids are common pests. You can identify mealybugs because they have a cottony, mealy substance on their bodies and stems. Aphids are small insects that are often green, white, or black. They suck the juices out of the plant, causing the leaves to turn yellow and fall off. Cut off any affected parts of your peace lily, including leaves and stems, to eliminate the pests.


Aphids, which can enter through the leaves, also spread the fungus. Look for cottony white material on the plant. Remove any affected parts of the plant, and spray your peace lily with water at least once a day to keep it moist.

Light Requirements:

The peace lily does best in medium light (indirect sunlight). Ensure the surrounding environment is well-ventilated, with good air circulation around the plant.


The peace lily prefers temperatures between 60- and 70 degrees F. it can tolerate temperatures as low as 50 degrees but not below 40 degrees.

Plant Problems:

The peace lily has few major problems and is quite durable in the home environment. Peace lily leaves turning yellow generally indicates a problem with the plant itself, while yellowing along with spots on leaves is more likely a symptom of a problem, such as an insect damage or disease.


Peace lilies are beautiful flowers that require very little attention during their life cycle. Maintaining healthy plants requires only a few basic steps. Try to keep your peace lily in a warm place with plenty of light, and add fertilizer as needed. Be sure to water your plant well, so the soil stays moist throughout the summer and keep it away from direct sunlight during its rest period. It’s also good practice to water your plants regularly during the season but never allow them to become dry by letting them sit in dry soil for too long.

Small shrubs or trees can be easily grown in pots or large flowerbeds with little effort or maintenance for those who care for their peace lily. Peace lilies can be planted in small containers and kept indoors without too much trouble. Peace lilies are easy to care for because they survive on only a little bit of light and water. They do best in a warm environment but can still grow in cooler weather.

It’s important to remember that although these plants are tolerant of indirect sunlight, they need some sunlight to thrive properly. If your plant is getting insufficient light, you may notice its leaves begin to turn yellow or otherwise develop brown spots on them. Make sure you’re moving your plant around, so it receives the right amount of sunlight at all times during the day.
