Pocket BotanistCheck these first
- Check if the soil is dry deeper than an inch.
- Measure the humidity level in the room.
- Inspect the leaf tips for signs of crispiness.
Likely causes
Low Humidity
Most likelyHow to tell: The very tips of the leaves become dry, crispy, and brown while the rest of the leaf remains green.
What to do: Mist the leaves daily with a spray bottle or place a humidifier nearby. Grouping plants together can also help create a more humid microclimate.
Underwatering
PossibleHow to tell: The brown tips are accompanied by leaves that feel brittle and the soil pulls away from the edges of the pot.
What to do: Water the tree thoroughly until water runs out of the drainage holes. Keep the soil consistently moist by checking it every 3 to 7 days.
When to worry
Minor browning is common in indoor environments with air conditioning or heating. Worry if the brown patches start spreading toward the leaf stem.
Stopping it coming back
Keep the soil moist and increase the ambient humidity around the plant.
