Proper watering builds deep roots and drought-resistant grass. Here's how to water smarter.
The Core Principle
Water deeply and infrequently rather than shallow and often.
Deep watering → roots grow deep → better drought tolerance
Shallow watering → shallow roots → constant watering needed
How Much Water
1 inch per week during growing season (including rainfall)

Watering Schedule
Best Time: Early morning (4-8 AM) - low evaporation, grass dries before evening
By Season
Spring: 1 inch/week, often natural rain provides enough
Summer: 1-1.5 inches/week, one deep soaking or two ½-inch waterings
Fall: Gradually reduce to ½-¾ inch as temps cool
Winter: Minimal to none (warm-season grasses dormant)
By Grass Type
Bermuda: Moderate needs, very drought-tolerant
St. Augustine: Higher needs, less drought-tolerant
Zoysia: Low to moderate needs
Tall Fescue: Higher needs, especially in summer
Signs You're Doing It Wrong
Overwatering:
-
✓
Spongy feel

Blue-gray color
-
✓
Blades fold or curl
-
✓
Slow to spring back
System Optimization
-
✓
Adjust heads for proper coverage

Separate zones for sun/shade
-
✓
Use smart controllers (weather-based)
Water Conservation
-
✓
Raise mowing height (reduces evaporation)
-
✓
Aerate compacted soil
-
✓
Choose drought-tolerant grass
-
✓
Zone irrigation properly
