Check these first

  1. Touch the soil to see if it is dry.
  2. Check the light levels at the plant's current location.
  3. Inspect the undersides of leaves for pests.

Likely causes

  1. Drying soil

    Most likely

    How to tell: The leaves turn yellow and crispy starting from the edges or tips. This happens when the soil dries out between waterings.

    What to do: Keep the soil constantly moist or keep the pot in a shallow tray of water. Ensure the soil never dries out completely, as this plant thrives in wet conditions.

  2. Insufficient light

    Possible

    How to tell: The lower leaves turn yellow and eventually fall off while the plant looks stretched. This occurs when the plant does not get enough full sun.

    What to do: Move the plant to a spot with direct, full sun. If growing indoors, place it in a south facing window or use a high intensity grow light for 10 to 12 hours daily.

When to worry

Worry if the yellowing spreads rapidly across the entire plant. It is normal for the very oldest leaves at the base to yellow and drop as the plant matures.

Stopping it coming back

Maintain a consistent water level by keeping the pot in a shallow water tray. Provide as much direct sunlight as possible.

Questions people ask

Can I let the soil dry out slightly?
No, this plant prefers to be constantly moist or even submerged in shallow water. Drying out will quickly stress the plant.
Does yellowing mean I have aphids?
Aphids usually cause distorted new growth rather than overall yellowing. Check the tips of the stems for small insects if the yellowing is accompanied by curling.
