End-of-Year Lawn Checklist — 2026 Wrap for Ohio

December 31 is my favorite day to walk a property. The lawn is dormant, the trees are bare, the beds are stripped back, and you can see everything that’s actually going on without summer leaves and August grass hiding the problems. By tomorrow morning the calendar flips and I’ll be quoting 2027 contracts, so today is the day I walk my own Circleville property and most of my key client lawns one last time before the new year.

This is the end-of-year wrap checklist I run. Designed for Central Ohio cool-season lawns in Pickaway, Franklin, Fairfield, Ross, and Fayette counties. If you do nothing else with your lawn between Christmas and New Year’s, do this one walk.

What should be on my end-of-year lawn checklist for Central Ohio?

Your end-of-year lawn checklist for Central Ohio should cover six categories: turf condition, soil and bed status, tree and shrub health, hardscape and structures, equipment and storage, and documentation for 2027 planning. Plan one to two hours for a thorough walk on a quarter to half-acre residential property, with a notes app and your phone camera. The walk on December 31 catches things you cannot see in spring once growth resumes.

I’m going to walk through each category with what to look for, what to write down, and what to fix now versus in March.

Turf condition: what does the dormant lawn tell me about next year?

A dormant lawn is honest. Color variations, wear patterns, and bare spots are visible in a way they aren’t during peak green growth. Walk your lawn slowly and look for:

• Bare or thin patches that didn’t fill in by mid-October
• Snow mold rings if you’ve had snow cover (gray or pink circular patches)
• Vole or rodent tunnels visible at soil surface
• Compaction footprints that hold their shape underfoot
• Frost heave at the edges of beds or driveway joints
• Stripe patterns from last summer’s mowing direction overuse

The mowing direction one is small but matters. If you mowed in the same direction every week last summer, you’ll see a faint striping pattern in the dormant lawn that shows ruts and compression. Plan to vary your mow direction by 30 to 45 degrees each visit in 2027.

On a Pickerington property I walked last December 31, the dormant turf showed three bare patches in the front yard that I hadn’t been able to see when I aerated and overseeded in September because of leaf coverage. We re-spread seed and starter fertilizer in early April 2026 and those patches filled in by June. December walk caught what September service missed.

Soil and bed status: what’s the soil doing right now?

Dig a small test hole 4 inches deep in a representative section of lawn with a hand spade. You’re looking for:

• Soil texture: does it crumble or hold a tight clay ball?
• Soil color: dark brown is good, pale gray is low organic matter
• Root depth: where does the white root mass stop?
• Moisture level: is it wet, damp, or dry at depth?
• Worm activity: are there any visible earthworm tunnels?

If your roots stop at 1.5 to 2 inches, you have a shallow root system that will struggle in any 2027 summer dry stretch. The fix is aeration in early September and consistent mowing height above 3.5 inches all season. OSU Extension’s turfgrass root development resources document the direct relationship between mowing height and root depth in cool-season lawns, and the difference between a 2-inch cut and a 4-inch cut shows up in dormant-season root inspections.

For beds, walk every mulched area and note:

• Mulch depth (it should still be 2 to 3 inches in most beds)
• Edge crispness or encroachment
• Perennial crowns visible above soil line (these may need protection)
• Standing water or ice pooling at the lowest point of each bed
• Stake or trellis structures that should come out before March

On a Lancaster bed I walked December 30 a few years ago, three Knockout rose crowns were exposed and getting hit by single-digit overnight lows. We mulched them deeper that afternoon and lost zero plants. Two neighbors who skipped that step lost the same variety to crown damage by spring.

Tree and shrub health: what does the bare canopy reveal?

December is the best month to look at trees. The canopy is bare, the branch structure is visible, and you can see every dead limb, included bark joint, and crossing branch. Walk each significant tree and write down:

• Any dead limbs over 2 inches in diameter (these need professional removal)
• Included bark or co-dominant leader issues that may fail in a storm
• Bark damage at the base from string trimmer impact (this is often fatal)
• Frost cracks running vertically up the trunk on the south side
• Galls, cankers, or oozing wounds that suggest disease
• Crossing branches that will rub themselves to failure within 2 to 3 years

String trimmer damage at the base of young trees is the most common landscape injury I see in Central Ohio yards. It often kills trees over 3 to 5 years and the homeowner blames “the species” or “the weather.” Wrap the base of every young tree with a 4-inch tall plastic guard or maintain a 3-foot mulch ring with no grass touching the trunk.

For shrub work, write down which boxwoods, hollies, and other evergreens look stressed or browning. Winter browning in evergreens is usually wind desiccation and the fix is anti-desiccant spray in November, but if you missed it this year, plan for it in November 2027.

Hardscape and structures: what needs attention before spring?

Walk every hardscape surface and note damage. Winter exposes problems that summer hides:

• Cracks in concrete walkways or driveways
• Heaved or sunken pavers in patios or pathways
• Loose or rotted fence posts (push each one to test)
• Sagging gutters or downspout joints
• Deck board cupping or rotted hand-rail joints
• Retaining wall lean or block displacement

The fence post one is critical. December and January freeze-thaw cycles loosen marginal posts and the first March windstorm takes them down. If a post wobbles more than half an inch at the top when you push it, plan to reset or replace it before the next windy stretch.

On a Grove City property I serviced two years ago, three fence posts failed in a March windstorm that the homeowner could have caught in his December walk. The repair cost three times what a preemptive reset would have cost.

Equipment and storage: is my gear ready for storage or 2027 service?

If you DIY, December is winterization month for your mower, trimmer, and blower. Specifically:

• Drain fuel or run a stabilizer through gas equipment per manufacturer specs
• Pull spark plugs, fog the cylinder, and re-install per the operator’s manual
• Sharpen or replace mower blades before storage, not in March
• Clean undercarriage of mower deck to prevent corrosion
• Pull batteries from cordless equipment and store at 40 to 60 percent charge
• Lubricate cables and pivot points on all hand equipment

The blade sharpening is the one most people skip. A blade sharpened in December is sharpened to a clean edge with time to dry the surface and apply light oil before storage. A blade sharpened in March is rushed because you want to mow this weekend, and the edge geometry is often worse.

Documentation: what do I write down for 2027 planning?

This is the highest-leverage step of the whole walk. Open a notes app and write down, in plain English:

• What worked on this lawn in 2026 (list at least three things)
• What didn’t work (list at least two things)
• What I plan to do differently in 2027
• What single project I want to complete in 2027
• What I need from my contractor that I didn’t get in 2026

This document, three to five paragraphs total, is what you re-read in mid-February when you’re locking in your 2027 service plan. Without it, you’ll forget half of what just happened on your property this year.

What should I fix between now and January 15?

Three things that benefit from immediate action:

• Cover exposed perennial crowns with additional mulch if they’re sitting above the soil line
• Wrap or guard the base of any young tree that’s vulnerable to rodent damage
• Mark any irrigation heads or low-voltage lighting that’s at risk from plows or shovels

Everything else from this walk goes into your 2027 planning document and gets addressed in March, April, or whenever the right service window opens.

Common end-of-year lawn checklist mistakes I see

• Walking the property at noon when the sun hides ice and contrast
• Skipping the soil test hole because “it’s frozen” (it’s usually workable in the top 3 inches into mid-December)
• Forgetting to photograph problems, then forgetting they exist by April
• Letting equipment sit in the shed without winterization
• Writing down what to do but not when to do it
• Trying to fix everything in December instead of triaging into now-vs-spring
• Not setting next year’s service contract before January 15

The contract timing matters most. The contractors with capacity for spring 2027 are the ones who lock contracts in January and February. Wait until April and the calendar gets thin.

Quick end-of-year lawn checklist

• Walk the dormant lawn, photograph thin areas and patterns
• Dig a test hole, document soil texture and root depth
• Inspect every tree for dead limbs and trunk damage
• Check every fence post, gutter joint, and hardscape crack
• Winterize all mower, trimmer, and blower equipment
• Write 2026 lessons and 2027 plan in three to five paragraphs
• Cover exposed perennials and wrap vulnerable young tree trunks
• Book 2027 services by mid-February
