Likely causes
Insufficient light
Most likelyHow to tell: The stems stretch out, become thin, and lean toward the nearest light source.
What to do: Move your plant to a spot that receives direct sunlight or very bright indirect light. If you are growing it indoors, a south facing window is usually best.
Crowding
PossibleHow to tell: The plant looks thin and weak because it is competing with other plants for light and space.
What to do: Give your rush more room by moving it away from other plants. If the pot is very crowded, consider dividing the plant into smaller clumps.

When to worry
If the stems are so weak they cannot stand upright, the plant is struggling significantly. It is normal for the plant to grow tall and slender if it is healthy and well lit.
Stopping it coming back
Place the plant in a location with full sun to partial shade to encourage strong, upright growth.

Questions people ask
- Will leggy stems recover?

- Does this plant flower?
- This plant does produce small, inconspicuous flowers in the summer. It needs plenty of direct sun to bloom successfully.
