Check these first

  1. Check if the soil is bone dry or completely saturated.
  2. Look for signs of pests on the undersides of the yellowing leaves.
  3. Examine if the yellowing is happening on older leaves or new growth.

Likely causes

  1. Watering Issues

    Most likely

    How to tell: Leaves turn yellow and may drop off if the soil is consistently too wet or too dry. The plant looks wilted or stressed.

    What to do: Adjust your watering schedule to keep the soil consistently moist but not soggy. Use your finger to check the soil depth before adding more water.

  2. Nutrient Deficiency

    Possible

    How to tell: Older leaves turn yellow while the veins remain green. This often 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. If the plant is very root bound, consider repotting it into fresh soil.

When to worry

A few yellow leaves at the base of the plant are normal as it ages. Be concerned if the yellowing spreads rapidly across the entire plant.

Stopping it coming back

Maintain a consistent watering routine and feed the plant lightly during the spring and summer. This keeps the foliage healthy and green.
