Peace lilies are popular among houseplant enthusiasts for their lush green leaves and gorgeous white flowers.
These tropical plants are relatively easy to maintain, but they can face occasional issues.
One such issue many peace lily owners face is the appearance of brown tips on their leaves.
Understanding the possible causes and what can be done to prevent this can help keep your peace lily vibrant and healthy.
Common Reasons Why Peace Lily Leaf Tips Turn Brown
- Inadequate Watering
- Low Humidity
- Fluoride or Chlorine in Water
- Exposure to Direct Sunlight
1. Inadequate Watering
One of the most common reasons for brown tips on peace lilies is improper watering.
This is because peace lilies prefer moist but not soggy soil.
Giving your peace lily plant too much water can cause root rot and brown leaf tips.
While underwatering can lead to dry and wilted leaves with brown tips.
How to properly water peace lilies?
Peace lilies should be watered once a week, but this may change based on the plant’s environment and size. Watering needs will vary depending on whether your peace lily is outdoors or indoors.
The key is to allow the top 2 cm of the soil to dry out between watering.
Another important tip is to avoid overhead watering.
Make sure the surrounding soil of the peace lily is soaked and that its pot has drainage holes.
2. Low Humidity
Peace lilies are tropical plants, which means they thrive in environments with high humidity.
If the air around them is too dry, it can lead to leaf tip browning.
What is the ideal humidity level for peace lilies?
Increase humidity and maintain a consistent temperature around your peace lily.
This can be achieved by using a humidifier, placing the plant on a tray of pebbles filled with water, or frequently misting the peace lily leaves with water.
While peace lily flowers benefit from regular fertilisation, too much can lead to salt buildup in the soil.
And a sudden change in soil moisture and quality can cause peace lily leaf tips to turn brown.
Do peace lilies need fertilising?
Fertilisation can be beneficial for a peace lily to flower.
But you should do so sparingly — about once every six weeks during the growing season (spring and summer) and once every three months during the off-season (fall and winter).
Ensure to use a balanced, water-soluble houseplant fertiliser and always follow the instructions on the packaging.
4. Fluoride or Chlorine in Water
Peace lilies are sensitive to fluoride and chlorine, commonly found in tap water.
These chemicals can accumulate in the soil, leading to browning leaf tips.
Is water quality important to peace lily plants?
Consider using filtered or distilled water for watering your peace lily.
If this isn’t possible, fill a container with tap water and leave it out overnight. This allows the chlorine to evaporate before you water the plant.
5. Exposure to Direct Sunlight
Peace lilies prefer bright, indirect light.
Exposure to direct sunlight can scorch the leaves, causing them to turn brown at the tips.
How much light do peace lily plants need?
Keep your peace lily in a spot with bright but indirect sunlight. If your peace lily is exposed to direct sunlight, consider using a curtain or shade to filter the light.
Remember, every peace lily is unique and may require slightly different care depending on its specific environment and condition.
If your peace lily continues to have brown tips despite following these tips, consider seeking advice from a local garden centre or plant expert.
