Watering Fescue Lawns: Best Practices for Cool-Season Turf

Optimal Watering Time

Morning, preferably before noon, so grass dries before nightfall—reduces disease. Adjust for rainfall and restrictions (georgiadrought.org).

Measuring Sprinkler Output

1. Six identical weighted containers in sprinkler pattern.
2. Run 1 hour; measure depth; average = inches/hour.
3. Calculate run time for 1 inch.

Soil-Specific Adjustments

• Clay: Slow absorption; split irrigation if runoff.
• Sandy: Fast absorption, quick drying; split weekly inch into two ½-inch applications 3 days apart.

Drought Stress Signals

Fescue needs water when leaves turn light gray-green and curl. If footprints remain visible, it's wilted.
