Find out Why Your Peace Lily Leaves are Turning Yellow by knowing the common causes and easy fixes to keep your plant green and healthy again.
Peace lilies are easy to care for, which makes them a popular choice for indoor plants. They grow well in low light and can produce beautiful white flowers in spring, even for beginners. A healthy plant has large, shiny green leaves. But if care is not right, the leaves can turn yellow or brown. One or two yellow leaves are normal, but if many leaves change color, it may mean there is a problem. The good news is that most of these problems are easy to fix.
Why Your Peace Lily Leaves are Turning Yellow
Root Bound Plant
If your peace lily is root-bound, it can also get root rot. This stops the plant from taking in nutrients from the soil. As a result, the leaves may turn yellow.
To fix this, remove the damaged roots and repot the plant in a pot that is a few inches bigger than the root ball.
Insufficient Watering
Peace lilies like soil that stays slightly moist, so do not let it dry out completely between watering. If you notice wilting, yellow, or brown leaves, the plant may not be getting enough water. Next time, water your peace lily when the top layer of soil feels dry to the touch.
Excessive Watering
If you see yellow leaves, your peace lily may be getting too much water. Overwatering can cause root rot, which damages the roots. If the soil stays wet for many days after watering, it is a clear sign of overwatering.
Let the soil dry out fully before watering again. Then follow a regular watering routine. If there is slight root rot, cut off the soft, damaged roots and repot the plant in fresh soil.
Lack of Humidity
Peace lilies need humidity to grow well, just like other tropical plants. If the air is too dry, the leaves can wilt and turn yellow. Keep your plant in a humid place like a bathroom, or use a humidifier once a day to give it enough moisture.
Aging
Older peace lilies may get yellow leaves more often than young plants. When you see new leaves growing, you can remove the yellow ones. This helps the plant look neat and stay healthy. Even though the plant will not live forever, you can still help it grow well for a long time.
Poor Water Quality
Tap water often contains minerals like chlorine and fluoride. These can build up in the plant and cause the leaves to turn yellow.
Peace lilies are not very fussy, but it can help to use clean or filtered water. Try using purified water and see if the leaf color improves.
Improper Nutrient Levels
Peace lilies are easy to care for and usually do not need much fertilizer. But if the plant does not get enough nutrients like nitrogen, iron, or magnesium, the leaves can turn yellow or lose their color.
An easy way to fix this is to repot the plant in fresh soil, because old soil loses nutrients over time. You can also try using a small amount of liquid fertilizer to see if it improves the leaf color.
Extreme Temperatures
Peace lilies are tropical plants and like warm temperatures. They do not do well below 65°F (18°C), though they can handle a short time around 50°F (10°C). Keep them in a warm place in your home, but away from strong direct sunlight. They grow best between 65°F and 85°F (18°C to 29°C). If the plant gets too cold, the leaves can turn yellow.
Do not keep your peace lily in a drafty room or outside where temperatures change a lot or become too cold.
Overexposure to Light
Peace lilies are tropical plants that grow under taller trees in the rainforest. This means they like soft, indirect light, not strong direct sunlight. Too much sun can burn the leaves and make them turn brown or yellow.
Move your peace lily to a place with indirect light to keep it healthy and happy.
Pests
Peace lilies usually do not get pests, but sometimes insects like mealybugs, aphids, or spider mites can attack the plant. These pests can stress the plant and cause the leaves to change color.
You can use neem oil on your peace lily to help keep pests away and protect the plant.
How to Fix Leaf Yellowing In Peace Lilies
- Water your peace lily with filtered or distilled water instead of tap water.
- Check the pot from time to time to make sure the plant is not root-bound.
- Remove yellow or damaged leaves so new ones can grow.
- Add a little compost to the top of the soil to give extra nutrients.
- Wipe the leaves to remove dust and gently mist them with water.
- Feed the plant at the start of the growing season and then every two months.
- Check the soil often to make sure you are not giving too much or too little water.
