Check these first
- Check the humidity levels in the room.
- Feel the soil to see if it is completely dry.
- Inspect the leaves for signs of dust buildup.
Likely causes
Low humidity
Most likelyHow to tell: The tips turn crisp and brown while the rest of the leaf remains green. This happens most often during winter when heaters are running.
What to do: Place a humidifier nearby or group your plants together to create a microclimate. You can also mist the foliage occasionally, though this is less effective than a humidifier.
Underwatering
PossibleHow to tell: The soil is bone dry and pulling away from the sides of the pot. The brown tips feel brittle to the touch.
What to do: Give the plant a thorough soak until water runs out of the bottom. Maintain a consistent schedule of watering every 7 to 14 days.
