How Often Should You Mow Your Lawn in Connecticut?

Written By Beck Curtis

If you’re a homeowner in Watertown or nearby, you’ve likely asked: “How often should I mow my lawn in Connecticut?” It all boils down to your grass type, the season, and local weather—and here’s the conversational breakdown, plus how Blue J’s Lawn Care in Connecticut can help.

Why Mowing Frequency Matters 

Mowing regularly keeps turf healthy, reduces weeds, and boosts curb appeal. Follow the one‑third rule:
cut no more than one-third of the blade’s height each time—crucial for cool-season grasses common in CT

Cool‑Season Grass Growth in CT

In Connecticut, lawns are mainly cool-season grasses: Kentucky bluegrass, tall/fine fescue, and perennial ryegrass. These thrive in cooler temps and grow most in spring and fall. CT folks usually mow weekly, but growth surges may need mowing every 4–5 days during peak seasons 


Blue J’s Lawncare’s Reccomended Seasonal Guide to Mowing

Spring (April–May)

  • Begin mowing late April–early May after the grass reaches ~3–4″ ().

  • Start high (3–4″) and follow one‑third rule.

  • Expect 5–7-day intervals, possibly earlier during rapid growth

Summer (June–August)

  • Maintain weekly or every 5–7 days, ideally when it’s dry

  • During drought, raise mower height and stretch out frequency to conserve moisture

Fall (September–October)

  • Grass growth picks up again—weekly mowing is key

  • Lower blades slightly to prep for winter—but don’t scalp.

Winter (November–March)

  • Oftentimes, it is best to avoid mowing your grass past November to prevent damaging the plant.

  • Grass may still grow slow; if needed, mow every 3–6 weeks if it’s over ~2″ tall

  • Wait for dry, mild days and avoid mowing frozen or wet grass
