Causes of Brown Leaves on Peace Lilies
Several factors can cause brown leaves on peace lilies, including too much or too little light, too much or too little water, temperature stress, nutrient deficiencies, and pests.
- Too much light: Peace lilies need bright, indirect light to thrive. If they are in a spot that gets direct sunlight, the leaves will start to turn brown.
- Too little light: If peace lilies are not getting enough light, the leaves will also start to turn brown. They will also start to droop and the flowers will stop blooming.
- Too much water: Peace lilies like their soil to be moist but not soggy. If they are getting too much water, the leaves will begin to turn brown and rot. The roots will also start to rot.
- Too little water: If peace lilies are not getting enough water, the leaves will begin to turn brown and wilt. The flowers will also wilt.
- Temperature stress: Peace lilies prefer warm temperatures between 60 and 85 degrees Fahrenheit. If it is too hot or too cold outside, the leaves may start to turn brown.
- Nutrient deficiencies: Peace lilies need nutrients to grow and thrive. If they are not getting enough nutrients from their soil, the leaves may start to turn brown and wilt. Common nutrient deficiencies include nitrogen, phosphorus, and potassium.
- Pests: Pests can also cause brown leaves on peace lilies by feeding on the plant’s foliage. Common pests include aphids, mealybugs, scale insects, spider mites, and whiteflies.
Why Are My Peace Lily Leaves Turning Brown
There are several possible reasons for brown leaves on a peace lily, including:
- too much sun
- too little water
- too much fertilizer
- pests or diseases
What Causes Brown Leaves On A Peace Lily
One of the most common reasons for brown leaves on a peace lily is too much direct sunlight. Peace lilies are native to the shady rainforests of South America, so they’re not used to strong sunlight. If you notice that your peace lily’s leaves are turning brown, try moving it to a location with less direct sunlight. Other causes of brown leaves on peace lilies can include:
- Too much water: Peace lilies like to be kept moist, but they don’t like to sit in water. If the soil around your peace lily is constantly wet, it could lead to root rot, which will cause the leaves to turn brown and die.
- Too little water: If you don’t water your peace lily enough, the leaves will start to turn brown and wilt. Peace lilies need to be watered about once a week, or when the soil feels dry to the touch.
- Fertilizer burn: Peace lilies are sensitive to fertilizer, so it’s important not to over-fertilize them. If you notice that the leaves are turning brown after you fertilize your peace lily, try using a weaker fertilizer or fertilizing less often.
- Pests: Aphids, mealybugs, and spider mites can all infest peace lilies and cause the leaves to turn brown. If you see any pests on your plant, try treating them with an insecticidal soap or neem oil.
Why Are My Peace Lily’s Leaves Turning Brown
One of the most common reasons that peace lily’s leaves turn brown is due to a lack of humidity. Peace lilies are native to the tropical rainforests of South America, so they thrive in humid environments. If the air in your home is too dry, the leaves of your peace lily will start to turn brown and crispy. To increase the humidity around your peace lily, you can do a few things. First, try putting the peace lily pot on a tray of pebbles and water. The water will evaporate and help to increase the humidity around the plant. You can also run a humidifier near your peace lily. Another option is to mist the leaves of your peace lily with water every few days.
If you think that a lack of humidity is not the problem, there are a few other things that could be causing your peace lily’s leaves to turn brown. One possibility is that you are watering your plant too much. Peace lilies like to have moist soil, but they don’t like to be sitting in water. Be sure to empty any drainage tray after watering and only water your plant when the top inch or so of soil is dry. Another possibility is that you are using tap water instead of distilled or filtered water. The chemicals in tap water can build up over time and damage the Peace Lily’s roots, causing the leaves to turn brown. Use distilled or filtered water instead. If you’ve ruled out all of these other possibilities, it’s possible that your plant is just getting too much sun. Move it to a location where it will get indirect sunlight instead of direct sunlight and see if that helps.
Peace Lily Leaves Turning Brown – Causes
There are several reasons for peace lily leaves turning brown, including too much or too little water, cold damage, or a fungal disease. If your peace lily is getting too much water, the leaves will start to turn brown and wilt. The excess water will cause the roots to rot, and the plant will eventually die. Peace lilies like to be kept moist but not soggy, so be sure to check the soil before watering and only water when the top inch or so of soil is dry.
If your peace lily is not getting enough water, the leaves will also start to turn brown and wilt. The plant will need to be watered more frequently in order to prevent further damage. Cold damage is another possible cause of brown leaves on peace lilies. If the temperature drops below 60 degrees Fahrenheit, the leaves will start to turn brown and wilt. Peace lilies are tropical plants and need warm temperatures to thrive. Be sure to keep them away from drafts and protect them from cold weather if you live in an area with a cooler climate.
Lastly, a fungal disease called Colletotrichum gloeosporioides can cause brown spots on peace lily leaves. This disease thrives in warm, humid conditions and can quickly spread if not treated early. If you see brown spots on your peace lily leaves, remove any affected leaves and dispose of them immediately. You can also try treating the plant with a fungicide designed for use on houseplants.
