Check these first
- Observe how many hours of direct sun the plant gets daily.
- Look for nearby trees or structures that might be blocking the light.
- Check if the plant has outgrown its space.
Likely causes
Insufficient Light
Most likelyHow to tell: The grass blades are pale, thin, and stretching toward the nearest light source. The plant lacks the dense, upright habit it is known for.
What to do: Move the plant to a location that receives full, direct sun for at least 6 to 8 hours a day. If it is in a permanent spot, trim back nearby trees or shrubs that might be casting shade.
Overcrowding
PossibleHow to tell: The plant is competing with other nearby perennials for light and nutrients. The center of the clump may look sparse or dead.
What to do: Divide the plant in early spring to give it more room to grow. Remove any competing weeds or nearby plants that are crowding the base.

When to worry
Leggy growth is not usually fatal, but it makes the plant look weak and prone to flopping over. It is a sign that the plant is not thriving in its current environment.
Stopping it coming back
Plant your grass in a location with full sun and give it enough space to spread out as it matures.

Questions people ask
- Does this grass need full sun?
- Yes, it thrives in full sun. It will become leggy and weak if grown in partial shade.
- Can I prune it to make it fuller?
- Pruning won't fix legginess caused by lack of light. You must move the plant to a sunnier spot for it to grow properly.
