How Long Should I Run Each Sprinkler Zone in Michigan?

Homeowners often ask for one number they can enter into every sprinkler zone. Unfortunately, a fixed runtime can overwater one area while leaving another dry. The right schedule depends on how quickly each zone applies water and how well the soil absorbs it.

Different sprinkler heads apply water differently

Spray heads, rotary nozzles, and rotors can have very different precipitation rates. Zones with different head types should not automatically receive the same runtime.

Soil and slope matter

Heavy soil may absorb water slowly and benefit from shorter watering cycles with soak time between them. Sloped areas can also produce runoff before enough water reaches the root zone.

Adjust for weather and season

Spring watering needs are usually different from peak summer needs. Rainfall, temperature, wind, shade, and established plant material all affect demand.

Watch the lawn, not just the timer

Persistent dry areas may indicate poor coverage or a sprinkler problem rather than insufficient runtime. Increasing the entire zone can waste water without fixing a misaligned or clogged head.
