Check these first

  1. Touch the soil to see if it is damp or dry.
  2. Check the water level in your container.
  3. Look for white mineral deposits on the pot or soil.

Likely causes

  1. Drying out

    Most likely

    How to tell: The soil surface feels dry to the touch and the tips of the leaves are brittle. This happens quickly if the water level drops too low.

    What to do: Increase your watering frequency to ensure the soil stays constantly moist. Never let the soil dry out completely, even for a day.

  2. Mineral buildup

    Possible

    How to tell: You see a white, crusty residue on the soil surface or the rim of the pot. This is caused by salts in tap water.

    What to do: Switch to using rainwater or distilled water for your plant. Flush the soil thoroughly with clean water to wash away excess mineral salts.

When to worry

A few brown tips are common as leaves age, but if the browning is spreading rapidly, your plant is stressed. It is normal for the oldest, lowest leaves to brown as the plant grows.

Stopping it coming back

Keep the soil consistently moist and use rainwater whenever possible to avoid mineral accumulation.
