A little lawn sense
How much water does my lawn need?
For many established lawns in active growth, about an inch a week from rain plus irrigation is a starting point. Soil, heat, grass and local restrictions can change that.
Measure what arrives
Use a rain gauge and a few straight-sided containers to check rainfall and sprinkler coverage. Uneven sprinklers can leave a dry patch even when the rest of the lawn is soaked.
Water the roots
Water early in the day. Aim to moisten the root zone, then let the surface dry between waterings. On sloping or heavy soil, use shorter cycles with pauses to prevent runoff.
Adjust for the lawn
New seed needs frequent light moisture at first; established grass needs a different schedule. Do not keep watering saturated soil. During drought, check local restrictions and Extension advice before choosing dormancy or continued irrigation.
Questions from the yard
Does an inch mean an inch from the sprinkler?
It means total water, including rain.
Should I water every evening?
Morning watering generally limits prolonged leaf wetness and reduces evaporation compared with the heat of the day.
