Check these first

- Inspect the base of the stems for softness or decay.
- Examine the soil drainage in the immediate area.
Likely causes
Poor Soil Drainage
Most likelyHow to tell: The plant stops growing, the leaves wilt despite moist soil, and the base of the stems may turn dark or slimy. The roots will look brown and mushy rather than firm and white.
What to do: Improve drainage by amending the surrounding soil with grit or sand. If the plant is in a container, ensure it has drainage holes and is not sitting in a saucer of water.
Excessive Watering
PossibleHow to tell: This is less common for this plant, as it is drought tolerant. Constant watering keeps the root zone in a state of perpetual saturation.
What to do: Reduce your watering frequency to every 10 to 14 days. Only water if the soil feels dry to the touch several inches down.

When to worry
If the plant is wilting and the base feels soft to the touch, it is a serious issue. It is rarely normal for this plant to show signs of root decay.
Stopping it coming back
Plant in well draining soil and avoid overwatering once the grass has established its root system.

Questions people ask
- Can I save a plant with root rot?
- If the rot is caught early, you can dig up the plant, trim away the mushy roots, and replant it in fresh, well draining soil. If the majority of the roots are black and slimy, the plant may not recover.
- Does Switchgrass need a lot of water?
- It needs consistent moisture while establishing, but once it is settled, it is very drought tolerant and prefers to dry out between waterings.
