  1. Check if the soil is bone dry several inches down.
  2. Examine the soil surface for white mineral deposits.
  3. Observe if the browning is happening during a heatwave.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The tips turn brown and crispy while the rest of the leaf looks dull. This often happens during prolonged hot, dry weather.

    What to do: Give the plant a deep soak to ensure water reaches the root zone. Aim to water every 7 to 10 days during the peak of summer.

  2. Salt buildup

    Possible

    How to tell: Brown tips appear even when the soil seems adequately moist. You might see a white crust on the soil surface.

    What to do: Flush the soil with a large volume of water to wash away accumulated salts. Avoid using chemical fertilizers near the base of the plant.
