Check these first

  1. Check if the soil feels soggy or muddy.
  2. Dig up a small sample to inspect the roots.
  3. Test your irrigation system for leaks.

Likely causes

  1. Overwatering

    Possible

    How to tell: The grass looks wilted even when the soil is wet. You might notice a sour smell coming from the soil.

    What to do: Reduce your watering frequency to every 2 to 4 days. Ensure your soil has proper drainage by aerating the lawn. Allow the surface to dry slightly between waterings.

  2. Poor soil drainage

    Possible

    How to tell: Water pools on the surface long after rain or irrigation. The grass roots appear dark and mushy instead of white and firm.

    What to do: Core aerate the lawn to improve oxygen flow to the roots. Consider amending heavy clay soils with organic matter. Avoid walking on the lawn when it is extremely wet.

When to worry

Worry if the grass turns yellow or brown and pulls up easily from the ground. This indicates the root system has already failed.

Stopping it coming back

Water deeply but infrequently to encourage strong roots. Aerate annually to prevent soil compaction and water logging.

Questions people ask

Can I save grass with root rot?
If caught early, you can save it by correcting drainage and watering habits. If the roots are completely black and mushy, you may need to reseed.
How do I know if I am watering too much?
