Does curling mean my grass is dying?

Not necessarily, but it is a sign of stress. If you address the water needs quickly, the blades will usually uncurl within a few hours.

How often should I water to prevent curling?

Check your soil every 2 to 5 days. If the top inch feels dry, it is time to water.

Likely causes

Drought Stress
Most likely
How to tell: The grass blades roll inward to conserve water, often turning a dull, grayish green color.
What to do: Increase your watering frequency to ensure the soil stays damp to the touch. Apply water early in the morning to minimize evaporation.
Root Damage
Possible
How to tell: The grass curls even when the soil feels damp, suggesting the roots cannot absorb the available water.
What to do: Inspect the soil for signs of grubs or soil compaction. Aerate the lawn to improve oxygen flow to the roots and treat for pests if necessary.

When to worry

Worry if the curling persists after a deep watering, as this indicates a deeper root issue. It is normal for grass to curl slightly during the hottest part of a dry afternoon.

Stopping it coming back

Keep the soil consistently damp and apply a light layer of mulch or topdressing to help retain moisture.
