Only water if extended dry period

Watering by Grass Type

Cool-Season Grasses

Tall FescueKentucky BluegrassPerennial Ryegrass
Water Need:Moderate to High
Best Time:Early morning (6-10 AM)
Frequency:2-3 times per week
Root Depth:6-8 inches deep

Prefer cooler temperatures, need consistent moisture

Warm-Season Grasses

Bermuda GrassZoysiaBuffalo Grass
Water Need:Low to Moderate
Best Time:Early morning (6-9 AM)
Frequency:1-2 times per week
Root Depth:6-10 inches deep

More drought tolerant, less water needed

Common Watering Mistakes

Frequent Shallow Watering

High Impact

Problem: Creates shallow root system, increases disease risk

Solution: Water deeply but less frequently to encourage deep root growth

Evening Watering

High Impact

Problem: Grass stays wet overnight, promotes fungal diseases

Solution: Always water in early morning (6-10 AM) for best results

Overwatering During Cool Weather

Medium Impact

Problem: Wastes water, can cause root rot and fungal issues

Solution: Reduce watering frequency when temperatures drop below 60°F

Ignoring Rainfall

Medium Impact

Problem: Leads to overwatering and water waste

Solution: Use rain gauge and adjust schedule based on natural precipitation

Watering During Peak Sun

Medium Impact

Problem: High evaporation rate, potential leaf burn from water droplets

Solution: Water early morning when evaporation is minimal

Troubleshooting Water Issues

Brown Patches Appearing

Possible Causes:

  • Apply balanced fertilizer
  • Test soil pH and adjust if needed
  • Aerate compacted areas

Water Running Off

Possible Causes:

  • Compacted soil
  • Steep slope
  • Clay soil
  • Thatch buildup

Solutions:

  • Aerate lawn to improve water penetration
  • Water in shorter cycles with breaks
  • Remove excess thatch
  • Add organic matter to improve soil structure

Uneven Growth Patterns

Possible Causes:

  • Inconsistent watering
  • Sprinkler coverage gaps
  • Soil variations

Solutions:

  • Check sprinkler coverage and adjust heads
  • Perform sprinkler audit with catch cups
  • Hand water dry spots as needed
  • Test soil in different areas

Water Conservation Tips

Install rain sensors on automatic irrigation systems
Use drought-tolerant grass varieties for your area
Mulch around trees and garden beds to retain moisture
Fix leaks in irrigation systems promptly
