American germander · Teucrium canadense

Why does my American germander have root rot?

Root rot happens when the soil stays wet for too long, preventing the roots from getting oxygen. Check the roots for a mushy texture or a foul smell.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Gently pull the plant from its pot to inspect the root color.
  3. Check if the drainage holes are blocked.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil remains soggy and the base of the stems may turn black or soft.

    What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, repot the plant into fresh, well draining soil after trimming away the black, mushy roots.

  2. Poor Drainage

    Most likely

    How to tell: Water pools at the bottom of the pot or the soil stays saturated for more than a week.

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

When to worry

If the roots are slimy and falling apart, the plant is in critical condition. It is normal for a few roots to be brown if the plant is very old, but they should still feel firm.

Stopping it coming back

Only water when the top inch of soil is dry and never let the plant sit in a saucer of standing water.
