Lamb's ear · Stachys byzantina

Why is my Lamb's ear rotting at the base?

Lamb's ear hates having wet feet and often suffers from crown rot when moisture stays trapped around the base. Check your soil drainage and watering habits first to see if the plant is sitting in a puddle.

Check these first

  1. Check if the soil feels soggy or swampy.
  2. Inspect the crown for soft or mushy tissue.
  3. Verify that the plant is not buried too deeply in the soil.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The base of the plant turns mushy and brown, and the leaves start to collapse.

    What to do: Stop watering immediately and let the soil dry out completely. If the soil is heavy, amend it with grit or sand to improve drainage.

  2. Poor Drainage

    Possible

    How to tell: Water pools around the crown after rain or irrigation.

    What to do: Lift the plant and replant it on a slight mound or in a raised bed. This helps water drain away from the sensitive crown.

When to worry

If the entire center of the plant is mushy and smells bad, it is likely too late to save that section. Remove the rotted parts to prevent spread.

Stopping it coming back

Always plant in well draining soil and avoid watering directly onto the crown of the plant.

Questions people ask

Can I save a plant with root rot?
If you catch it early, you can trim away the rotted parts and improve drainage. If the rot has reached the main roots, the plant is usually lost.
How often should I water?
Only water when the soil is completely dry, which is usually every 7 to 14 days. Never let the plant sit in standing water.
