Pocket BotanistCheck these first
- Check the humidity level in your room.
- Look for white mineral crust on the soil surface.
- Feel the leaf tips to see if they are brittle or soft.
Likely causes
Low Humidity
PossibleHow to tell: The leaf tips turn crisp and brown while the rest of the leaf remains green. This often happens in winter when indoor heating dries out the air.
What to do: Place the plant on a pebble tray filled with water or use a humidifier nearby. Aim for humidity levels above 50 percent.
Salt Buildup
PossibleHow to tell: Brown tips appear even when you water regularly, often accompanied by a white crust on the soil surface. This is caused by minerals in tap water.
What to do: Flush the soil thoroughly with distilled or rainwater to wash out excess salts. Switch to using filtered water for future waterings.

When to worry
Brown tips are rarely fatal but indicate the plant is unhappy with its environment. If the brown patches spread to the whole leaf, you should address the cause immediately.
Stopping it coming back
Use distilled water and keep the humidity high to prevent tip burn. Avoid over-fertilizing, which can also lead to salt accumulation.
