[1] Botrytis Blight (Gray Mold)
Botrytis blight, also called gray mold, is a fungal disease that affects many types of plants, including peace lilies. If you do notice any signs of the disease, be sure to remove affected leaves and flowers immediately to help prevent the spread of the fungus. The best way to prevent botrytis blight is to keep your peace lily in a well-ventilated area with plenty of air circulation. The fungus thrives in warm, humid conditions and can cause the leaves of affected plants to turn brown or black.
Control and Management
If your peace lily’s leaves are turning brown or black, it’s likely due to one of these 11 causes. But don’t worry, there’s a fix for each one!
1. Too Much Sunlight
They’re used to filtered sunlight, so too much direct sunlight can scorch their leaves. Peace lilies are native to the shady rainforests of Central and South America.
If your peace lily is getting too much sun, move it to a shadier spot. You’ll know it’s in the right spot when the leaves start to green up again.
Not Enough Sunlight 2.
Peace lilies need some sunlight to thrive, but too much sun will scorch their leaves. If your peace lily is getting too little sun, it will start to lose its color and its leaves will droop.
You’ll know it’s in the right spot when the leaves start to green up again. Move your peace lily to a spot where it will get some indirect sunlight.
3. Incorrect Watering
Overwatering will cause the leaves to turn brown and mushy, while underwatering will cause the leaves to turn brown and crispy. Peace lilies are sensitive to changes in their environment, and that includes the amount of water they’re getting.
To water your peace lily correctly, stick your finger in the soil. If it’s dry to the touch, it’s time to water. If it’s wet, it doesn’t need any more water.
4. Poor Drainage
If the soil doesn’t drain well, the roots will start to rot, which will cause the leaves to turn brown and mushy. Peace lilies need well-drained soil to thrive.
You can also add some perlite or sand to the pot to improve drainage. To fix this, replant your peace lily in a pot with well-draining soil.
5. Fertilizer Burn
This will cause the leaves to turn brown and crispy. Peace lilies are sensitive to fertilizer, and too much fertilizer will burn their roots.
If you think your peace lily has fertilizer burn, stop fertilizing and flush the soil with water to remove the excess fertilizer. To avoid fertilizer burn, use a half-strength fertilizer and apply it every other month.
6. Temperature Stress
Peace lilies are tropical plants, so they prefer warm, humid conditions. If the temperature drops too low, the leaves will turn brown and crispy.
If the temperature drops below 60 degrees Fahrenheit, move your peace lily to a warmer spot. To avoid temperature stress, keep your peace lily in a warm, humid room.
7. Pest Infestation
Peace lilies are susceptible to pests, such as aphids, mealybugs, and spider mites. These pests will suck the sap out of the leaves, causing them to turn brown and crispy.
You can also use an insecticide, but be sure to follow the instructions carefully. To get rid of pests, wash your peace lily with water and soap.
Disease 8.
Peace lilies are susceptible to diseases, such as root rot and fungal leaf spot. These diseases will cause the leaves to turn brown and mushy.
If your peace lily is already infected, you can try using a fungicide. To prevent diseases, water your peace lily from the bottom and keep the leaves dry.
Transplant Shock 9.
This will cause the leaves to turn brown and crispy. Peace lilies don’t like to be moved around, and they can go into shock when they’re transplanted.
To avoid transplant shock, acclimate your peace lily to its new environment by slowly moving it into the new spot over a period of days or weeks.
Dry Air 10.
Peace lilies prefer humid conditions, so they don’t do well in dry air. This will cause the leaves to turn brown and crispy.
To increase the humidity around your peace lily, mist
[2] Bacterial Brown Spot
Bacterial brown spot is caused by a bacteria called Pseudomonas cichorii. Bacterial brown spot is a common problem with peace lilies. The bacteria can enter the plant through wounds or via the roots. The spots are often surrounded by a yellow halo. If your peace lily does develop bacterial brown spot, you can try treating it with a copper-based fungicide. The spots are brown or black and can range in size from a small dot to a large blotch. Bacterial brown spot is difficult to control and can quickly kill a peace lily. Once the bacteria are inside the plant, they multiply and spread, causing the brown spots to form. The best way to prevent the disease is to avoid wounding the plant and to water it with clean, filtered water.
Control and Management
But what do you do when your peace lily’s flowers start to turn brown or black? If you’re a peace lily owner, you know that these beautiful flowers can brighten up any room.
There are a few possible reasons for this. First, it could be that the plant is not getting enough light. Peace lilies need bright, indirect light to thrive. If your plant is in a dark corner or isn’t getting enough natural light, its flowers may start to fade.
Over-watering can cause the peace lily’s roots to rot, which can lead to brown or black flowers. Second, the plant may be getting too much water. Be sure to check the soil before watering your plant, and only water when the top inch or so of soil is dry.
Finally, the plant may be getting too much fertilizer. If you’re using a general-purpose fertilizer, be sure to dilute it before applying it to your plant. Peace lilies are sensitive to chemicals, so it’s important to use a fertilizer that is specifically designed for them.
If your peace lily’s flowers are turning brown or black, don’t despair. With a little troubleshooting, you should be able to figure out the cause and get your plant back to its beautiful self in no time.
