Likely causes
Poor Drainage
PossibleHow to tell: The soil stays muddy for days after watering and the grass turns a sickly yellow. The roots will look dark, slimy, and smell unpleasant.
What to do: Aerate the soil to improve oxygen flow to the roots. If the drainage is very poor, you may need to amend the soil with organic matter.
Overwatering
PossibleHow to tell: The grass looks thin and weak, and the soil is consistently saturated. The roots lose their firm, white appearance and turn brown.
What to do: Reduce your watering frequency to allow the top inch of soil to dry slightly. Ensure your watering schedule does not exceed the needs of your specific soil type.

When to worry
If the grass is turning brown and pulling away from the soil easily, the root system is likely too far gone. Immediate action is needed if you see widespread yellowing.
Stopping it coming back
Ensure your soil has good structure and avoid letting water pool on the surface for long periods. Only water when the soil needs it to stay damp, not soaking.
