Check these first

  1. Check if the soil is bone dry.
  2. Feel the texture of the brown tips to see if they are crispy.
  3. Observe if the browning is happening on new or old leaves.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The leaf tips turn crispy and brown while the rest of the leaf feels dry. The soil pulls away from the edges of the pot.

    What to do: Water the plant thoroughly until water runs out the bottom of the pot. Maintain a schedule of watering every 7 to 14 days.

  2. Low Humidity

    Possible

    How to tell: The tips brown slowly even when the soil is moist. The air in your home feels very dry, especially during winter.

    What to do: Group your plant with others to create a humid microclimate. You can also place a small tray of water and pebbles near the base.

When to worry

A little browning on the very tips is common if the air is dry. Worry if the brown patches start moving inward toward the center of the leaf.

Stopping it coming back

Keep the soil consistently moist but not soggy. Avoid placing the plant near heating vents or drafty windows.
