Check these first

  1. Move the plant to a brighter location.
  2. Check the soil moisture to ensure it is not waterlogged.
  3. Look for any signs of pests on the underside of the leaves.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The lower leaves turn yellow and drop off while the plant looks stretched out. The foliage loses its deep green luster.

    What to do: Move the plant to a spot with bright indirect light. If you have a sunny window, ensure it is protected from harsh afternoon sun.

  2. Overwatering

    Most likely

    How to tell: The yellowing starts on the older leaves and the soil feels constantly soggy. The leaves may feel soft or limp.

    What to do: Reduce your watering frequency immediately. Ensure the soil dries out slightly between waterings and check that your pot has proper drainage.

When to worry

A single yellow leaf at the bottom of the plant is normal as it sheds old growth. If multiple leaves turn yellow at once, it is a sign of stress.

Stopping it coming back

Provide consistent bright indirect light and follow a strict watering schedule based on soil dryness.

Questions people ask

Will yellow leaves turn green again?
No, once a leaf has turned yellow, it will not return to green. It is best to let the plant shed it naturally or remove it if it is completely dead.
Does the Queensland kauri need fertilizer?
A balanced fertilizer during the growing season can help prevent nutrient deficiencies that cause yellowing. Use a diluted liquid fertilizer once a month in spring and summer.
