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 at the undersides of leaves for any signs of pests.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than a few days.

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

  2. Nutrient Deficiency

    Possible

    How to tell: Older leaves turn yellow while veins remain green, often indicating a lack of nitrogen. This happens if the plant has been in the same soil for a long time.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Avoid overfeeding, as this can burn the roots.

When to worry

It is normal for the very bottom leaves to yellow and drop as the plant ages. Be concerned if the yellowing spreads rapidly to the upper foliage.

Stopping it coming back

Maintain a consistent watering schedule and provide well draining soil to keep roots healthy.
