Common figwort · Scrophularia nodosa

Why is my Scrophularia nodosa suffering from root rot?

Root rot is a serious issue for figwort because it thrives in moist soil that must remain well drained. Check your soil moisture and drainage holes immediately to see if the roots are sitting in standing water.

Check these first

  1. Smell the soil for a foul odor.
  2. Check if the pot has drainage holes.
  3. Feel the soil to see if it is waterlogged.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil stays soggy for days and the base of the stems may turn mushy or dark. You might notice a sour or swampy smell coming from the pot.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, ensure it has drainage holes and remove any standing water from the saucer.

  2. Poor Drainage

    Most likely

    How to tell: Water pools on the surface of the soil for a long time after watering. The roots cannot breathe because the soil is too dense or compacted.

    What to do: Repot the plant into a container with fresh, well draining potting mix. Mix in some perlite or coarse sand to improve aeration and drainage.

When to worry

If the stems are black and mushy at the base, the rot has likely spread too far to save the plant. It is time to worry if the plant wilts even when the soil is wet.

Stopping it coming back

Only water when the top inch of soil feels dry to the touch. Use a pot with plenty of drainage holes to prevent water from pooling.
