How do I know if my Water clover has root rot?

Root rot in Water clover is tricky because the plant is meant to be submerged. It usually happens when the water becomes stagnant or contaminated.

Check these first

  1. Smell the water for a foul odor.
  2. Lift the plant to inspect the color of the roots.
  3. Check if the water has been changed recently.

Likely causes

  1. Stagnant water

    Most likely

    How to tell: The water smells foul and the roots appear slimy or dark brown.

    What to do: Change the water immediately and rinse the roots gently. Ensure you are refreshing the water at least once a week to keep it oxygenated.

  2. Bacterial infection

    Possible

    How to tell: The roots turn mushy and the plant begins to collapse.

    What to do: Remove the affected parts of the plant and discard them. Clean the container thoroughly before adding fresh, clean water.

When to worry

If the roots are black and mushy, the plant is in serious trouble. Act quickly to save the healthy portions of the rhizome.

Stopping it coming back
