Chinese holly · Ilex cornuta

Why is my Chinese holly showing signs of root rot?

Root rot is less common for this plant, as it is quite hardy, but it usually happens when the soil stays soggy for too long. Check the soil moisture and the drainage holes in your pot first.

Check these first

  1. Feel the soil at least 2 inches deep.
  2. Check the drainage holes for blockages.
  3. Smell the soil for any signs of decay.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow or brown and feel soft, while the soil remains wet to the touch for weeks. You might also notice a sour smell coming from the pot.

    What to do: Stop watering immediately and let the top 2 to 3 inches of soil dry out completely. If the plant is in a container, ensure it has drainage holes and remove any standing water from the saucer.

  2. Poor Drainage

    Possible

    How to tell: The water sits on the surface of the soil for a long time after you water. The plant looks wilted even though the soil is saturated.

    What to do: Repot the holly into a container with better drainage holes using a well draining potting mix. Add perlite or coarse sand to the soil to improve aeration.

When to worry

If the stems feel mushy or the roots are black and slimy, the plant is likely beyond saving. It is normal for a few older leaves to drop occasionally, but widespread wilting is a major concern.

Stopping it coming back

Always wait until the top inch of soil is dry before watering again. Ensure your pot has adequate drainage to keep roots healthy.
