Check these first

- Check if the plant is leaning toward a window.
- Review your recent fertilization schedule.
Likely causes
Insufficient light
Most likelyHow to tell: The stems grow long, thin, and pale as they reach toward the nearest light source. The plant loses its dense, tufted appearance.
What to do: Move your grass to a spot that receives at least 6 to 8 hours of direct sunlight daily. If you are growing it indoors, place it directly in a south facing window or use a high intensity grow light.
Excessive nitrogen
PossibleHow to tell: The grass grows very rapidly with soft, floppy blades that cannot support their own weight. This often happens if the soil is too rich or if you have over fertilized.
What to do: Stop all fertilization immediately. Switch to a lean, sandy soil mix if the current potting medium is too organic or moisture retentive.

When to worry
It is not a health emergency, but it is a sign that the plant is not getting the environment it needs to thrive. You cannot fix existing leggy growth, so you may need to trim it back once you provide better light.
Stopping it coming back
Keep your Esparto grass in the sunniest spot you have and avoid using nitrogen heavy fertilizers.

Questions people ask
- Can I prune back the leggy growth?
- Yes, you can trim the long, floppy blades back to encourage a fresh, tidy start. Just make sure you fix the lighting issue first, or it will simply grow back leggy again.
- Will my grass recover its shape?
- The existing stems will not shrink back, but new growth will be much tighter and more upright once the plant receives enough direct sun.
