Check these first

- Check if other plants are blocking its light.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are stretching out and leaning toward the nearest light source.
What to do: Move the plant to a location with bright, indirect light. If you are growing it indoors, consider placing it in a south or west facing window.
Crowding
PossibleHow to tell: The plant is very dense and the inner stems are pale or thin.
What to do: Divide the clump into smaller sections during the spring. This gives each piece more space and light to grow properly.

Questions people ask
- Will my plant fill back out?
- If you move it to a brighter spot, new growth will be much denser. You can trim back the long, leggy stems to encourage a bushier shape.
- Does this plant flower?
- Marsh foxtail does produce small, foxtail-like flower spikes in the wild. It needs plenty of bright light and consistent moisture to bloom successfully in a home setting.
