Russian sage · Salvia yangii

Why is my Russian sage dying from root rot?

Russian sage loves dry, lean soil and hates having wet feet. If your plant is wilting or turning mushy at the base, root rot is the most likely culprit. Check your soil drainage immediately.

Check these first

  1. Feel the soil two inches below the surface.
  2. Check if the planting site is in a low spot that collects water.
  3. Inspect the base of the stems for soft or discolored tissue.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly damp or muddy to the touch. You might notice a sour smell coming from the base of the plant.

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

  2. Poor Drainage

    Possible

    How to tell: Water pools around the base of the plant after rain or irrigation. The plant sits in a low spot where water collects.

    What to do: Transplant the sage to a raised bed or a mound of soil to encourage water runoff. Ensure the planting site is in full sun to help moisture evaporate quickly.

When to worry

If the stems are black and mushy at the base, the plant is likely beyond saving. Some yellowing after heavy rain is normal, but it should recover once the soil dries.

Stopping it coming back

Always plant Russian sage in well draining soil and avoid supplemental irrigation once the plant is established.

Questions people ask

Can I save a plant with root rot?
If the rot is caught early, you can stop watering and improve drainage. If the roots are already black and slimy, it is usually too late.
