How do I fix root rot on my Lady's Mantle?

It is less common for Lady's Mantle to get root rot, and this usually happens when the soil is too heavy or the plant sits in standing water. Check the roots immediately if the plant is wilting despite having moist soil.

Check these first

  1. Check the soil for a sour or rotten smell.
  2. Examine the roots for a mushy texture.
  3. Verify that the pot has adequate drainage holes.

Likely causes

  1. Poor Drainage

    Most likely

    How to tell: The plant wilts and the base of the stems turns brown or black. The roots will look dark, slimy, and smell foul.

    What to do: Gently lift the plant and trim away any mushy, black roots with sterile scissors. Repot in fresh, well draining potting mix and ensure the pot has drainage holes.

  2. Overwatering

    Possible

    How to tell: The soil stays wet for days and the foliage starts to yellow or collapse. The roots are unable to breathe due to constant saturation.

    What to do: Adjust your watering schedule to allow the soil to dry slightly between waterings. Use a moisture meter or your finger to check that the soil is dry 2 inches down before adding more water.

Stopping it coming back

Use a light, airy potting mix and never let the pot sit in a saucer of standing water.
