Check these first

  1. Check if the air in your home is very dry.
  2. Verify your watering schedule to ensure you are not letting the plant get too dry.
  3. Look for signs of salt buildup on the soil surface.

Likely causes

  1. Low humidity

    Possible

    How to tell: The tips of the leaves become dry, crispy, and brown while the rest of the leaf looks healthy. This often happens in winter when indoor heating dries out the air.

    What to do: Group your plant with others to create a humid microclimate. You can also place the pot on a tray filled with pebbles and water to boost moisture.

  2. Inconsistent watering

    Possible

    How to tell: The leaves show brown, dry edges because the plant has been allowed to dry out completely between waterings. The foliage may also lose its vibrant color.

    What to do: Establish a consistent watering routine by checking the soil every 3 days. Ensure the soil is evenly moist but not soggy.

When to worry

Worry if the brown spots start spreading toward the center of the leaves. It is normal for the very oldest leaves at the bottom of the plant to brown and drop as the plant grows.

Stopping it coming back

Keep the plant away from direct drafts from heaters or air conditioners. Maintain a steady watering rhythm based on the soil moisture.

Questions people ask

Should I trim off the brown tips?
You can trim them for aesthetic reasons using clean scissors. Cut just outside the green tissue to avoid damaging the healthy part of the leaf.
Does tap water cause brown tips?
Sometimes the minerals in tap water can build up and cause tip burn. If you suspect this, try using filtered or rainwater for a few weeks.
