Why is my Azure bluet suffering from root rot?

Root rot is a common issue for Azure bluets when they sit in soggy soil for too long. Check the soil moisture levels and drainage immediately to see if the roots are suffocating.

Check these first

  1. Feel the soil two inches deep to check for excess moisture.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Gently lift the plant to see if the roots look firm and white or mushy and brown.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly muddy and the base of the plant looks mushy or dark. You might notice a sour smell coming from the pot.

    What to do: Stop watering immediately and let the top inch of soil dry out. If the plant is in a pot, ensure it has drainage holes and repot into fresh, well draining soil if the roots are black.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface of the soil for a long time after watering. The plant stays wet even when you have not watered for several days.

    What to do: Mix perlite or coarse sand into your potting mix to improve aeration. Always use a pot with adequate drainage holes to allow excess water to escape.

When to worry

If the entire base of the plant is black and mushy, it is likely too late to save. Some minor root browning is normal if you have been slightly overwatering, but act fast.

Stopping it coming back

Only water when the top inch of soil feels slightly dry to the touch and ensure your potting mix is light and airy.
