Check these first
- Measure the current height of the grass.
- Observe how many hours of direct sun the area gets.
- Check if nearby trees have grown to block light.
Likely causes
Insufficient light
PossibleHow to tell: The grass blades grow long and thin as they stretch toward the sun. The lawn looks sparse and weak.
What to do: Trim back overhanging tree branches to increase direct sunlight. If the area is permanently shaded, consider overseeding with a shade tolerant grass variety. Ensure the grass gets at least 6 hours of light daily.
Mowing too high
PossibleHow to tell: The grass looks tall and floppy rather than dense and carpet like. It creates a shaggy appearance that is not typical for this species.
What to do: Lower your mower blade to the recommended height for velvet bentgrass. Mow more frequently to keep the height consistent. Never remove more than one third of the blade at once.

When to worry
Worry if the grass becomes so thin that weeds start taking over. Some seasonal variation in growth rate is normal.
Stopping it coming back
Mow regularly at the correct height and ensure the lawn is not competing with trees for light. Fertilize appropriately to encourage dense growth.

Questions people ask
- Does velvet bentgrass need full sun?
- It thrives in full sun but can handle partial shade. If it gets too little light, it will lose its dense, velvet texture.
- How often should I mow?
- Mow as needed to maintain your desired height, usually once or twice a week during the active growing season. Keep your mower blades sharp for a clean cut.
