Check these first

  1. Touch the top inch of soil to check for dampness.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Look for signs of pests on the undersides of the leaves.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for a long time.

    What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so extra water can escape.

  2. Nutrient deficiency

    Possible

    How to tell: Older leaves turn yellow while the veins remain green. This happens when the plant has been in the same soil for a long time.

    What to do: Apply a balanced liquid fertilizer diluted to half strength every 4 to 6 weeks during the growing season. If the plant is root bound, consider repotting it into fresh soil.

When to worry

It is normal for a few older leaves at the base to yellow and drop as the plant grows. Worry if the yellowing spreads rapidly across the entire plant.

Stopping it coming back

Maintain a consistent watering schedule and feed your plant regularly during the spring and summer months.
