- Look for signs of salt buildup on the soil surface.
Likely causes
Inconsistent Watering
PossibleHow to tell: The tips turn brown and crispy while the rest of the leaf feels dry. The soil surface feels hard and pulls away from the edges of the pot.
What to do: Water your plant every 3 to 7 days, ensuring the soil stays moist but not soggy. If the soil is bone dry, soak the pot in a basin of water for 20 minutes to rehydrate the root ball.
Low Humidity
PossibleHow to tell: This is less common for this plant, but usually happens when the air is extremely dry, causing the leaf edges to brown. You will notice the browning happens slowly over several weeks.
What to do: Group your plants together to create a more humid microclimate. You can also place a tray of pebbles and water near the plant to increase local moisture.

When to worry
Worry if the browning spreads rapidly toward the center of the leaves. It is normal to see a tiny bit of browning on the very oldest leaves at the base of the plant.
Stopping it coming back
Maintain a steady watering rhythm and avoid letting the soil dry out completely between waterings.
