You should water your grass deeply about 2 to 3 times per week, rather than daily. Each watering session should provide enough water to moisten the soil about 6 inches deep, which typically requires about 1 to 1.5 inches of water per week in total
. Key points for watering your lawn:
- Aim for about 1 to 1.5 inches of water per week, including rainfall
- Water deeply to encourage deep root growth; shallow daily watering leads to weak roots
- Typically, watering 3 times a week for about 20-30 minutes per session with an automatic sprinkler achieves this
- Adjust frequency based on temperature: water more often in hot weather (up to 3-4 times per week at 90°F or higher)
- Water early in the morning when evaporation is lowest, allowing grass blades to dry during the day and reducing disease risk
- Different grass types have different needs: warm-season grasses often require less frequent watering (once or twice a week), while cool-season grasses may need watering 2-3 times per week during hot periods
In summary, watering your lawn deeply 2-3 times a week with about 1 inch of total water per week is optimal for healthy grass growth. Adjust based on weather, grass type, and soil conditions to avoid over- or under-watering
