Check these first

  1. Stick your finger two inches into the soil to check for dampness.
  2. Ensure the pot has drainage holes at the bottom.
  3. Check the base of the stems for any signs of mushiness.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy. The soil stays damp for a long time after watering.

    What to do: Allow the soil to dry out significantly between waterings, usually every 7 to 14 days. Ensure your pot has drainage holes and never let the plant sit in a saucer of water.

  2. Crown Rot

    Possible

    How to tell: This is less common for this plant, usually caused by water pooling around the base of the stems. You will see yellowing leaves near the soil line and the base of the plant may look brown or mushy.

    What to do: Stop watering immediately and improve air circulation around the base. If the rot is advanced, you may need to repot the plant into fresh, well draining soil and cut away any damaged roots.

When to worry

Worry if the yellowing spreads rapidly across the whole plant. It is normal for the very oldest, lowest leaves to yellow and drop occasionally as the plant ages.

Stopping it coming back

Always let the soil dry out thoroughly before adding more water.
