Is my sensitive plant suffering from root rot?

Root rot is less common for this plant if you follow a strict watering schedule, but it happens when the soil stays soggy for too long. Check the smell of the soil first to see if it has a sour or swampy odor.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Check if the pot has drainage holes.
  3. Inspect the roots for mushy or dark sections.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves turn yellow and wilt even though the soil is wet. If you pull the plant out, the roots will look mushy and dark brown instead of firm and white.

    What to do: Stop watering immediately and let the soil dry out slightly. If the damage is severe, repot the plant into fresh, well draining soil after trimming away the dead roots.

  2. Poor drainage

    Possible

    How to tell: Water sits in the bottom of the pot or the saucer for days. This creates a suffocating environment where roots cannot breathe.

    What to do: Ensure your pot has drainage holes at the bottom. Use a potting mix amended with perlite to improve airflow around the roots.

When to worry

This is a serious issue that can kill the plant quickly if left unaddressed. If the stem base feels soft or mushy, the rot may have already spread too far.

Stopping it coming back

Always empty the saucer after watering and never let the plant sit in standing water.
