To keep a lawn healthy, it generally needs about 1 to 1.5 inches of water per week, either from rainfall or irrigation, to wet the soil to a depth of 6 to 8 inches where most roots grow

. This watering should be done deeply but less frequently to encourage deep root growth, which makes the lawn more resilient to heat and drought

. Recommended watering frequency and duration:

• Water about 2 to 3 times per week rather than daily, to avoid shallow roots and overwatering

• Typical schedules include watering twice a week for 30 minutes each session or three times a week for about 20 minutes each session, delivering roughly ⅓ to ½ inch of water per watering

• Adjust frequency based on temperature:
  • 1-2 times per week if temperatures are 60°F or lower,
  • 3 times per week between 70-80°F,
  • 3-4 times per week if 90°F or higher

Best time to water:

• Early morning, ideally between 6-10 a.m., is best to reduce evaporation and disease risk

• Evening watering before sunset (4-6 p.m.) is a second option, allowing water to soak in before night

• Avoid watering during windy conditions or immediately after mowing to prevent water loss and fungal problems

Additional considerations:

• Soil type affects watering needs; sandy soils drain quickly and may need more frequent watering, while clay retains water longer

• Use rain sensors or adjust watering based on rainfall to prevent overwatering

• Follow local water restrictions when applicable

In summary, water your lawn deeply about 2-3 times per week, providing a total of 1 to 1.5 inches of water weekly, preferably in the early morning, adjusting for weather and soil conditions to maintain a healthy, drought-resistant lawn
