Check these first

  1. Smell the soil for a musty or rotten odor.
  2. Check if the pot has drainage holes.
  3. Gently pull the plant out to inspect the roots.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and the stems feel mushy at the base.

    What to do: Remove the plant from its pot and trim away any black or slimy roots. Repot into fresh, well draining soil and ensure the pot has drainage holes.

  2. Poor drainage

    Possible

    How to tell: The soil stays wet for more than a week and has a sour or swampy smell.

    What to do: Switch to a pot with better drainage holes. Mix perlite into your potting soil to improve airflow to the roots.

When to worry

If the roots are mostly black and mushy, the plant may be too far gone to save. It is serious if the base of the stem is soft.

Stopping it coming back

Always empty the saucer after watering so the plant never sits in water.
