December Lawn Checklist for Central Ohio

December in Central Ohio is the month most homeowners assume the lawn season is over and stop thinking about the yard until April. I get it. The grass stopped growing three weeks ago, the leaves are mostly down, and the only outdoor chore on most peoples’ minds is hauling the Christmas tree in. But the truth I’ve learned from more than ten years of running mowers and plows across Pickaway, Franklin, and Fairfield counties is that the choices you make in December decide what your spring looks like.

This is the checklist I run on my own equipment and on every client property in December 2026. It’s also the list I wish more homeowners would tackle, because the calls I get in March about “why is my lawn so torn up” almost always trace back to something that should have been handled now.

What should I do for my Central Ohio lawn in December?

Wrap up leaf removal, give the turf one last short mow at 2.5 to 3 inches, drain your mower, stock deicer rated for the surface you have, and walk the property to flag anything that could be damaged by plows or salt. Those five items cover roughly 90 percent of what matters for a Central Ohio property between Thanksgiving and the first plowable snow event.

OSU Extension’s winter lawn guidance is clear that cool-season grasses like tall fescue and Kentucky bluegrass keep working underground long after they stop growing on top, and what damages them in winter is rarely the cold itself. It’s matted leaves smothering the crown, voles tunneling under a thick thatch layer, salt scorch along the curb, and plow blades catching the edge of beds because nobody marked them.

Final cleanup: what still needs to come off the lawn?

On a Circleville route last Tuesday I pulled 14 bags of oak leaves off a half-acre lot the homeowner swore she had “cleaned up” the weekend before. Oak leaves drop late and they drop heavy. If you cleaned up before Thanksgiving, you almost certainly have a second pass of work waiting for you.

The test I use: walk the lawn in good light and look for any spot where you cannot see green grass blades through the leaf layer. If the turf is hidden, those leaves need to come up or get mulched in with a final mow. Matted leaves trap moisture against the crown of the plant, and that’s where snow mold sets up over winter. I see pink and gray snow mold every spring on lawns that went into December buried under a leaf layer.

Sticks, dog toys, garden hoses, holiday extension cords, and decorative stakes also need to come off the lawn before the first snowfall. I once hit a forgotten ground stake at a Grove City property with a plow and watched it carve a 10-foot scar across the front yard. The homeowner felt terrible. I felt worse, because I had walked that property and missed it.

One last mow, and then drain the mower

Cool-season grass in Central Ohio usually stops adding meaningful blade height around the third week of November, but the lawn often still needs one cleanup pass in early December. I drop my decks to 2.5 to 3 inches for that final cut. That height is short enough to keep the canopy from matting under snow but tall enough to leave photosynthesis surface for the plant to keep building roots on the warmer December days when soil temps are still above 40 degrees.

After the final cut, the mower itself needs attention. Here’s the routine on my Toros and the homeowner Hondas I see in customer garages:

• Run the fuel tank dry, or add stabilizer and run it through the carburetor for two minutes
• Pull the spark plug, drop a teaspoon of oil into the cylinder, and turn the engine over by hand twice
• Sharpen or replace the blade now, not in April when every shop in Pickaway County has a two-week backlog
• Wipe the deck and spray the underside with a light coat of WD-40 to slow rust
• Pop the battery on a maintenance charger if it’s a rider or zero-turn

A mower stored wet, full of stale fuel, with a dull blade in December is a mower that costs you $180 at the shop in March. Five minutes of work now saves that.

Deicer and salt: buy now, store dry

Salt prices in Central Ohio jumped 12 to 18 percent over the last two winters depending on who you bought from. By mid-January 2025, three of my suppliers were on allocation and I had to drive to Marysville to fill a pallet. The lesson: stock now, while shelves are full and roads are dry.

For most residential walks and driveways, I recommend calcium chloride for fast melt on cold mornings and rock salt (sodium chloride) for general use above 15 degrees. Magnesium chloride is gentler on concrete but pricier per pound. If you have new concrete less than one year cured, do not put any chloride deicer on it. Use sand for traction and accept that you’ll be sweeping it up in April.

I’ll dig into the difference between salting concrete and asphalt in a separate post on the blog this week, but the short version is that asphalt forgives almost any deicer and concrete punishes the wrong choice for years.

Walk the property and flag the hazards

Every December I walk every commercial property and every residential plow client with a handful of orange driveway markers and a roll of reflective tape. The point is to find the things that disappear under six inches of snow and either kill my plow blade or get killed by it.

The hit list:

• Edges of beds and mulch rings (mark with stakes)
• Sprinkler heads (flag the head, not the box)
• Septic risers, well caps, French drain pop-ups
• Low-voltage landscape lighting (these snap off cheap)
• Curb stops, water shutoffs, gas meters
• Stone or paver edging that sits above grade
• Newly planted trees and shrubs that need a snow fence

On a Lancaster commercial property last December I caught three sprinkler heads I had installed in September that the seasonal blow-out crew had left flush with the turf. Marked them with 4-foot orange stakes. Saved the property manager probably $600 in spring repairs.

Bed and tree care that still pays in December

If the ground isn’t frozen yet, December is fine for cutting back ornamental grasses to about 6 inches, removing dead annuals from beds, and topping up mulch on any rings that got thin during fall cleanups. I don’t recommend pruning most ornamental trees in December because cut wounds heal slow in cold weather. Hold pruning until late February for most species, and call an arborist for anything bigger than what you can reach with a pole pruner.

Young trees planted within the last two seasons benefit from a tree wrap on the south and southwest sides of the trunk to prevent sunscald. I see this damage every February on Bradford pears and red maples in Pickerington and Canal Winchester neighborhoods that were built and planted within the last five years. White or light-colored wrap, applied bottom-up, removed in April.

Voles are the other December issue most people don’t think about until they see the damage. A vole-friendly winter setup is tall, ungroomed grass against a foundation or tree trunk, with mulch piled deep right up to the bark. The fix is to keep the turf short into December, pull mulch back 3 to 4 inches from trunks, and consider hardware cloth cages on any tree planted in the last three years.

Common December mistakes I see

• Stacking pumpkins and corn shocks on the lawn into December (they rot in place and kill the grass underneath)
• Leaving the garden hose connected to the spigot (one hard freeze and you have a burst pipe inside the wall)
• Storing the mower with fuel and a dirty deck (rust and gum the carburetor)
• Buying generic ice melt without reading the surface rating
• Forgetting to mark beds and sprinklers (plow damage you pay for in April)
• Letting fall leaf cover sit on the lawn into January (snow mold, vole runs, dead patches)

The pumpkin one is more common than you’d think. I pulled two soft, collapsed jack-o-lanterns off a Bexley lawn last December. The grass under them was yellow for 6 weeks the following spring.

What about feeding and overseeding?

December is too late for both in Central Ohio. The fall winterizer feed should have gone down between late October and mid-November, and any overseed work needed to be in by late September. If you missed both, write yourself a note for next year and focus on cleanup and equipment prep now.

If you want a head start on next season, get on the schedule for early-September aeration and overseed. Those slots fill fast and I’m already taking 2027 deposits from clients in Circleville and Pickerington who don’t want to chance it. For more on that work, see our guide on fall aeration and overseed timing.
