Fan Flower · Scaevola aemula

Why is my Fan Flower wilting and showing root rot?

Fan Flowers love moisture but hate sitting in water. If your plant looks sad despite damp soil, root rot is likely the culprit.

Check these first

  1. Check the soil moisture with your finger.
  2. Inspect the drainage holes for blockages.
  3. Gently lift the plant to see if the roots are dark and slimy.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil stays soggy for days and the base of the stems feels mushy or soft.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot without drainage holes, move it to one that has them.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface for a long time after you water.

    What to do: Repot the plant into a container with plenty of drainage holes. Use a well draining potting mix amended with perlite to improve airflow.

When to worry

If the stems are turning black or mushy at the base, the rot is advanced and the plant may not recover.

Stopping it coming back

Always check the top inch of soil before watering and ensure your pot has excellent drainage.

Questions people ask

Can I save a plant with root rot?
If you catch it early, trim away the black, mushy roots and repot in fresh, dry soil. If the majority of the root system is gone, it is usually best to start over.
How often should I water my Fan Flower?
Water every 3 to 7 days depending on the heat. Always wait until the top inch of soil feels dry to the touch.
