Likely causes
Poor drainage
Most likelyHow to tell: The soil feels swampy and smells sour or like rotten eggs. You might see the base of the plant turning mushy or dark brown.
What to do: Repot the sedge into a container with multiple drainage holes using a well draining potting mix. Trim away any black or slimy roots with clean scissors before replanting. Water only when the top inch of soil feels slightly less damp.
Overwatering
PossibleHow to tell: The leaves start to yellow and wilt even though the soil is consistently wet. The plant stops growing and looks generally unhappy.
What to do: Adjust your watering schedule to every 5 to 7 days instead of every 3 days. Always touch the soil before adding more water to ensure it needs it. Ensure the plant is in a spot with good airflow to help the soil dry out slightly between waterings.

When to worry
If the entire base of the plant is mushy and the roots are completely black, it is likely too late to save. It is normal for a few older outer leaves to brown as the plant grows.
Stopping it coming back
Use a porous potting mix and never let the pot sit in a saucer full of standing water for more than an hour.
