Check these first
- Feel the soil to see if it is wet or soggy.
- Check the bottom of the pot for standing water.
- Inspect the roots for a dark or mushy appearance.
Likely causes
Overwatering
Most likelyHow to tell: The base of the stems may look mushy or discolored. You might also notice a sour smell coming from the soil.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the soil remains waterlogged, repot the plant into fresh, well draining soil and trim away any black or slimy roots.
Poor Drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after you water. The pot might lack sufficient holes at the bottom.
What to do: Ensure your pot has drainage holes at the bottom to let excess water escape. If the pot is solid, move the grass to a container that allows for proper airflow and drainage.

When to worry
If the stems are turning black at the base and falling over, the plant is likely too far gone. It is normal for the plant to look slightly thirsty if you wait until the top inch of soil is dry.
Stopping it coming back
Only water when the top inch of soil feels dry to the touch. Always use a pot with drainage holes to keep the roots healthy.
