Check these first
- Measure how many hours of direct sun the plant gets.
- Check if nearby plants are shading your grass.
- Look at the base of the plant to see if it is crowded.
Likely causes
Insufficient Light
Most likelyHow to tell: The grass blades are long, thin, and leaning heavily toward the nearest light source.
What to do: Move the plant to a spot that receives full, direct sun for most of the day. If it is in a container, rotate it weekly for even growth.
Excessive Fertilizer
PossibleHow to tell: The grass grows very fast but the stems are weak and floppy.
What to do: Stop fertilizing for the season. Golden oat grass prefers leaner soil and does not need much feeding.

When to worry
Legginess is not fatal but it makes the plant prone to flopping over. It is a sign the plant is not in its ideal environment.
Stopping it coming back
Plant in a location with at least 6 to 8 hours of direct sun daily. Avoid overfeeding the soil.

Questions people ask
- Can I prune it back to make it bushier?
- Yes, you can cut the grass back in early spring to encourage fresh, dense growth. Do not cut it too short, just remove the old growth.
- Will it recover if I move it to more sun?
- It will not fix the existing long blades, but new growth will be much stronger and more compact.
