What is the maximum recommended irrigation rate for a typical turfgrass lawn?

The maximum recommended irrigation rate for a typical turfgrass lawn is 1 inch per week. This rate is based on the average water needs of most turfgrass species, ensuring proper moisture levels without overwhelming the soil's ability to absorb water.

Irrigating at 1 inch per week strikes a balance that can effectively support healthy grass growth while reducing risks such as runoff or waterlogging. Watering any more than this amount could lead to drainage issues and encourage diseases due to over-saturation, while less frequent watering might not provide sufficient moisture for the grass to thrive. Overall, this guideline helps maintain optimal turf quality and sustainable water usage.
