Check these first

- Observe the amount of direct sun the plant gets throughout the day.
- Inspect the base of the stems for any signs of rot or decay.
Likely causes
Overwatering
Most likelyHow to tell: The base of the plant feels mushy and the soil stays damp for more than two days after watering. You might notice a sour smell coming from the pot or ground.
What to do: Stop watering immediately and let the soil dry out completely. If the plant is in a container, ensure it has drainage holes and move it to a spot with more airflow.
Insufficient Light
PossibleHow to tell: The plant looks pale and stretched out while the lower leaves turn yellow. This happens when the grass does not get the full sun it craves.
What to do: Move your plant to a location that receives at least 6 to 8 hours of direct sunlight daily. If it is in a shaded corner, it will continue to struggle and lose color.

When to worry
Worry if the yellowing spreads rapidly across the entire clump. It is normal for a few older blades at the base to turn yellow as the plant matures.
Stopping it coming back
Only water when the soil is completely dry and ensure the plant is in a spot with full, unobstructed sun.
