Does curling mean my grass is dead?

Not necessarily, as curling is a survival tactic. If the grass stays brown and brittle after watering, it may have gone dormant or died.

Should I fertilize when the grass is curling?

Avoid fertilizing during periods of drought or heat stress. Wait until the grass is hydrated and healthy before applying any nutrients.

Why are my tall fescue blades curling? Causes and fixes

Check these first

Check the soil moisture with a probe or finger.
Look for signs of heat stress during the afternoon.
Evaluate your current irrigation schedule.

Likely causes

Drought Stress
Most likely
How to tell: The blades fold inward along the midrib to reduce surface area. This happens when the soil moisture drops below what the plant needs to stay turgid.
What to do: Apply 1 inch of water to the lawn using a sprinkler. Ensure the water penetrates deeply into the root zone.
Heat Stress
Possible
How to tell: The grass curls during the peak heat of the day but usually unfurls by morning. This is a natural defense mechanism against high temperatures.
What to do: Avoid mowing during the hottest part of the day. Keep your mower blades sharp to ensure a clean cut that does not further stress the grass.

When to worry

If the blades stay curled even at night or early morning, the lawn is in severe distress. It is normal for grass to curl slightly on very hot, sunny days.

Stopping it coming back

Mow at a higher setting to shade the soil and retain moisture. Water deeply once a week to build a strong root system.
