When to start mowing your lawn in Chicago (month-by-month)
Every March, Chicagoland homeowners ask the same question: is it time yet? Cut too early and you compact soggy soil and stress half-awake turf. Wait too long and the first cut is a hayfield. Here's the month-by-month version.
March: hands off (mostly)
Soil is usually too wet and the grass isn't actively growing. This is cleanup-prep month: book your spring cleanup, rake out matted leaves once things dry, and stay off soggy turf — footprints and mower ruts now last all season.
Early–mid April: the first cut window
When grass hits about 3 inches and is clearly growing — typically early-to-mid April in the city, a touch later in the outer suburbs — it's time. The first cut should be conservative: around 3 inches, never scalped. A high, clean first cut encourages the lawn to thicken instead of panic.
Late April–May: into the rhythm
Growth accelerates fast. By May, most Chicagoland lawns need weekly mowing to respect the one-third rule (more on that in our weekly vs. bi-weekly guide). This is also when crews' schedules fill — customers who set their recurring schedule in April get the best route slots.
A note on the suburbs vs. the city
Lakefront neighborhoods often green up a week before the western suburbs, and shaded lots in Glen Ellyn or north Downers Grove lag sunny ones in south Naperville. Watch the grass, not the calendar.
