5 Causes of Brown Leaf Tips on Peace Lilies

Now, let’s get to the main topic of this article – why peace lily leaf tips turn brown. There are several reasons why this might happen, and we will discuss each one of them below.

1. Overwatering

One of the most common causes of brown leaf tips in peace lilies is overwatering. Peace lilies prefer moist soil but can’t tolerate standing water. When you water your peace lily too frequently or give it too much water at once, the roots become waterlogged, and the plant can’t absorb oxygen. This can lead to root rot, which manifests as brown leaf tips, yellowing leaves, and a droopy appearance.

To avoid overwatering your peace lily, make sure to let the soil dry out slightly before watering again. You can check the moisture level by sticking your finger about an inch into the soil. If it feels dry, it’s time to water your plant. Also, make sure that your pot has drainage holes to allow excess water to escape.

2. Underwatering

On the other hand, underwatering can also cause brown leaf tips in peace lilies. When you don’t water your plant enough, the soil dries out, and the roots can’t absorb enough water to keep the plant healthy. This can lead to stress, which manifests as brown leaf tips and wilting leaves.

To prevent underwatering, make sure to water your peace lily regularly. However, don’t water it too frequently, as this can lead to overwatering.

3. Low Humidity

Peace lilies prefer high humidity levels, just like their natural habitat in the rainforest. When the air is too dry, the plant can’t absorb enough moisture, which can lead to brown leaf tips, especially on the edges.

To increase the humidity around your peace lily, you can mist its leaves with water or place a tray of water near the plant. You can also invest in a humidifier to maintain a consistent level of humidity in the air.

4. Direct Sunlight

Peace lilies prefer bright, indirect light, but can’t tolerate direct sunlight. When you expose your peace lily to direct sunlight, the leaves can get scorched, which can lead to brown leaf tips and yellowing leaves.

To prevent this, make sure to place your peace lily in a bright spot that receives indirect sunlight, such as near a window with a sheer curtain. You can also use a shade cloth to filter the sunlight if necessary.

5. Fertilizer Burn

Using too much fertilizer can also cause brown leaf tips in peace lilies. When you fertilize your plant too frequently or use too much fertilizer at once, it can burn the roots and the leaves, which can lead to brown leaf tips and yellowing leaves.

To prevent fertilizer burn, make sure to follow the instructions on the fertilizer package and don’t exceed the recommended dose. Also, don’t fertilize your peace lily during the winter months when it’s not actively growing.

Now that you know some of the causes of peace lily leaf tip browning, let’s explore some solutions to help you address the issue:

1. Adjust Watering Habits

To address overwatering, allow the soil to dry out completely before watering again. For underwatering, make sure to water the plant when the top inch of soil is dry to the touch. Also, make sure the plant is in a pot with proper drainage.

2. Increase Humidity

To increase humidity levels, you can mist your plant with water, place a tray of water near the plant, or use a humidifier.

3. Provide Indirect Sunlight

Move your peace lily to a spot with bright, indirect light to avoid direct sunlight.

4. Avoid Over-fertilizing

Follow the manufacturer’s instructions when fertilizing your peace lily and avoid using too much.


Can I cut off the brown leaf tips?

Yes, you can use a pair of sharp scissors to trim off the brown leaf tips. However, make sure to disinfect the scissors with rubbing alcohol before and after use to prevent the spread of diseases.

Can brown leaf tips indicate a disease?

Yes, brown leaf tips can be a sign of a disease such as bacterial or fungal infections. If you suspect that your peace lily is diseased, isolate it from other plants and consult a plant expert for advice.

In summary, brown leaf tips in peace lilies can be caused by various factors such as overwatering, underwatering, low humidity, direct sunlight, and fertilizer burn. To prevent brown leaf tips, make sure to water your plant properly, maintain high humidity levels, provide indirect sunlight, and fertilize it in moderation. If you notice brown leaf tips, you can trim them off, but make sure to address the underlying cause to prevent them from recurring.

With proper care, your peace lily can thrive and bring beauty to your home for years to come. By understanding the reasons why peace lily leaf tips turn brown, you can become a better plant parent and enjoy the many benefits of this lovely plant.
