How to tell if my Western wallflower has root rot?

It is less common for this plant to get root rot, but it usually happens when the soil stays wet for too long. Check the smell and color of the roots first.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Gently lift the plant to inspect the roots.
  3. Verify that the pot has drainage holes.

Likely causes

  1. Poor drainage

    Possible

    How to tell: The soil stays soggy and the plant looks stunted or yellow. The roots will appear mushy and dark instead of firm and white.

    What to do: Repot the plant into fresh, well-draining soil. Trim away any black or slimy roots before replanting.

  2. Overwatering

    Possible

    How to tell: The plant stops growing and the base of the stem feels soft. The soil remains damp even 14 days after watering.

    What to do: Allow the soil to dry out completely between waterings. Ensure you only water when the top few inches of soil are dry.

When to worry

Worry if the roots are black and mushy, as this is often fatal. It is normal for roots to be slightly brown if they are older, but they should still feel firm.

Stopping it coming back

Use a gritty, well-draining soil mix and never let the plant sit in standing water.
