Watering the lawn in a Greene County, Ohio summer: July

Cool-season grass slows down in July heat. You can keep it green with water or let it go brown and dormant.

Do this in July

  • Mowing

    Mow high, and not at all when the lawn is drought stressed.

    OSU advises against mowing a drought-stressed lawn and suggests minimizing traffic on it. [1]

  • Grubs and weeds

    Grubs are laying eggs.

    OSU says July is egg-laying time for most Ohio grubs. Watering bluegrass heavily in July can increase grub problems, and OSU's masked chafer fact sheet notes that grub eggs need moisture, so cutting back irrigation in July and early August may significantly reduce survival. [5][6]

  • Watering

    Water deeply when it wilts, or let it go dormant.

    Kentucky bluegrass can withstand four to six weeks of drought by going dormant. OSU's fact sheet suggests half an inch of water every four to six weeks to keep dormant crowns alive; OSU's 2026 summer newsletter says most years a dormant lawn needs no extra water at all. [5][7]

Nothing to do yet

  • Seeding

    Plan for late August.

    Line up seed now if you plan to fill thin areas this fall. [2]

  • Fertilizer

    Skip it, especially on a dormant lawn.

    OSU says to hold fertilizer while a lawn is drought dormant. [3][4]

  • Crabgrass and pre-emergents

    Nothing to apply.

    Preventer season is over.

  • Leaves and winter care

    Nothing to do.

    No leaf or winter work this month.
