There is no single calendar date when every Michigan homeowner should turn the irrigation system back on. Soil conditions, landscaping needs, overnight temperatures, and the forecast all matter.
Do not rush because of one warm week
Early spring can produce warm afternoons followed by freezing nights. Established lawns often need less supplemental irrigation during cool spring weather than they do in summer.
When you do start the system, inspect it
Bring the irrigation supply on gradually and run every zone. Watch for cracked heads, damaged fittings, valve issues, weak pressure, and water surfacing where it should not.
Reset the controller for spring
Do not automatically reuse a peak-summer schedule. Check the date, time, start times, watering days, seasonal adjustment, and rain-sensor operation.
Spring startup can reveal winter damage
Even a properly winterized system can develop unrelated wear or damage between seasons. Finding problems before regular watering begins prevents wasted water and landscape damage.
