Sneezewort · Achillea ptarmica

Why is my Sneezewort showing signs of root rot?

It is less common for this plant to suffer from root rot unless the soil stays soggy for too long. Check the drainage holes in your pot or the soil density in your garden bed first.

Check these first

  1. Feel the soil to see if it is saturated or muddy.
  2. Check the bottom of the pot to ensure water is draining freely.
  3. Smell the soil for any signs of decay.

Likely causes

  1. Waterlogged Soil

    Most likely

    How to tell: The leaves turn yellow and wilt even though the soil feels wet. You might notice a sour or swampy smell coming from the base of the plant.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, ensure the drainage holes are not blocked and the saucer is emptied after every watering.

  2. Heavy Clay Soil

    Possible

    How to tell: The plant grows very slowly and the base of the stems looks mushy or discolored. The soil stays wet for days after a light rain.

    What to do: Amend the surrounding soil with organic matter like compost or perlite to improve drainage. If the plant is severely affected, dig it up and replant it in a raised bed or a better draining area.

When to worry

If the stems are black and mushy at the base, the rot has likely spread too far. It is normal for the plant to look slightly thirsty on a very hot day, but it should perk up after a drink.

Stopping it coming back

Ensure your soil is loose and well draining, and always check the moisture level before adding more water.

Questions people ask

Can I save a plant with root rot?
If the rot is caught early, you can trim away the mushy roots and repot the plant in fresh, dry soil. If the roots are mostly black and slimy, it is usually best to start over.
How often should I water to prevent this?
Check the soil every 3 to 7 days. Only water when the top inch of soil feels dry to the touch.
