January lawn care in Greene County, Ohio

The grass is dormant. January is for mower maintenance and for knowing what to look for when the snow melts.

Do this in January

  • Mowing

    No mowing. Get the mower ready instead.

    OSU's spring checklist says to change the oil, replace the air filter, clean the spark plugs and sharpen or replace the blades. Buckeye Turf suggests sharpening after about 25 hours of use, which works out to twice a season for most yards. [1][2]

  • Leaves and winter care

    Watch for snow mold as the snow melts.

    Pink snow mold is probably the most common snow mold in Ohio. Gray snow mold shows up when snow cover lasts more than 40 to 60 days. If you find matted, discolored patches in spring, OSU suggests raking them lightly and watching for new shoots. [8]

Nothing to do yet

  • Seeding

    Not yet.

    Dormant seeding of thin spots is usually done in late winter, February into March, on ground that isn't frozen. [3][4]

  • Fertilizer

    Nothing to apply.

    OSU puts lawn feeding in April and May and again in September and October. [5]

  • Crabgrass and pre-emergents

    Nothing yet.

    Crabgrass preventer goes down in spring, when soil 2 inches deep reaches about 50°F. [6]

  • Grubs and weeds

    Nothing to treat.

    Grub and weed work starts in spring.

  • Watering

    No watering.

    OSU's watering advice is for the growing season. [7]
