Why is my Motherwort showing signs of root rot?

Root rot is a serious issue for Motherwort that usually stems from soil staying too wet for too long. Check the drainage holes in your pot first to ensure water is not pooling at the bottom.

Check these first

  1. Smell the soil for a musty or rotten odor.
  2. Check if the pot has drainage holes.
  3. Inspect the roots for a slimy or black appearance.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn mushy or brown, and the soil smells sour or swampy. You might notice the plant wilting even when the soil feels damp.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, remove it to check for slimy, black roots and trim away any that are mushy. Repot into fresh, well draining soil.

  2. Poor Drainage

    Most likely

    How to tell: Water sits on the surface of the soil for a long time after you water. The pot lacks holes or is sitting in a saucer full of standing water.

    What to do: Ensure your pot has functional drainage holes at the bottom. Never let the plant sit in a saucer of water for more than 30 minutes after watering. Use a potting mix amended with perlite to improve airflow.

When to worry

If the stem base feels soft or squishy, the rot has likely spread too far to save the plant. It is time to start over with a new cutting.

Stopping it coming back

Always check the soil moisture with your finger before watering, and only water when the top inch feels dry.
