Check these first
- Check if the soil feels soggy or smells bad.
- Inspect the drainage holes to see if they are blocked.
- Pull the plant gently from its pot to look at the root color.
Likely causes
Overwatering
Most likelyHow to tell: The base of the grass stems may feel mushy or smell sour. You might notice the foliage turning yellow or wilting even when the soil is wet.
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 potting mix and trim away any black or slimy roots with clean scissors.
Poor Drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after you water. The pot may lack sufficient holes or the soil may be too dense and heavy.
What to do: Ensure your pot has at least one large drainage hole at the bottom. Mix in perlite or coarse sand to your potting soil to improve aeration and water flow.

When to worry
You should worry if the stems are turning brown and mushy at the soil line, as this indicates the rot has spread. It is normal for a few older outer blades to brown as the plant grows.
Stopping it coming back
Always wait until the top inch of soil is dry before watering again. Use a pot with good drainage to keep the roots happy.
