Winter Tree Care: A Central Ohio Homeowner's Checklist

Why Winter Is Actually a Good Time to Think About Your Trees

Most homeowners in Columbus figure winter means the yard goes on autopilot. Leaves are down, the mower is in storage, and the trees just sit there. I get it. But winter is when I do some of my best work — and when neglected trees do some of their worst damage.

I'm Marcus Cedar, ISA Certified Arborist #OH-9912A, and I've been climbing trees and patching up storm damage in central Ohio for fifteen years. Every January I get calls from homeowners who wish they'd called in November. Walk through this checklist before the ground freezes and you'll start spring in much better shape.

Dormant-Season Pruning: Do It Now, Not Later

One of the biggest advantages of pruning in late fall and winter is that the tree's structure is completely visible. No leaves obscuring dead branches, crossing limbs, or weak attachment points. You can see exactly what needs to come out.

There's a second reason: wounds close faster on cuts made during dormancy. Disease pressure is low and insects that spread pathogens — oak wilt being the one I worry about most here in central Ohio — are not flying. Pruning oaks between November and March dramatically reduces that risk.

The Structural Issue That Causes Most Winter Damage

Central Ohio gets hit with ice storms. We all know it. What a lot of homeowners don't know is that the trees most likely to fail aren't necessarily the oldest or the biggest — they're the ones with codominant stems and overextended limbs.

A codominant stem is when a tree trunk splits into two roughly equal leaders. The junction between them is often weak, and when ice adds weight, that's where the split happens — sometimes taking down a fence, a car, or a corner of a roof. An overextended limb is one that's grown long and heavy without adequate taper or support. Same problem: ice loads it up and the limb cracks at the parent trunk.

Pre-winter structural pruning removes that leverage before the storm arrives. It's not cheap, but it's a fraction of what emergency tree removal and property repair cost. I tell every client: the best time to fix a bad branch is before it falls on something.

Handling Snow and Ice Load: What to Do (and What Not to Do)

After a heavy snowfall, it's tempting to go out and shake or knock the snow off branches. For shrubs and flexible young trees, gently brushing snow off with a broom — sweeping upward, not downward — is fine and prevents branches from bending and setting in an odd shape.

For established trees, do not knock ice off branches. This is the mistake I see most often and it causes real damage. Frozen wood is brittle. When ice has encased a limb, that limb is under stress but it's also being held in place by the ice. Whacking it or trying to knock the ice loose can snap the branch cleanly — you're doing the storm's work for it.

Let ice melt on its own. Keep people and vehicles out from under heavily loaded limbs, note which branches look at risk, and call us after the storm if you need assessments or cleanup.

If a limb does come down partially — still attached, hanging — don't try to remove it yourself. Hanging limbs under tension are unpredictable. Leave it and call a certified arborist.

Mulching the Root Zone for Winter

Mulch does two things in winter: it moderates soil temperature swings (the freeze-thaw cycles that heave roots) and it retains moisture in the root zone. A 3-inch layer of shredded wood mulch applied in a ring from about six inches away from the trunk out to the drip line is ideal.

The six-inch gap matters. Mulch piled against the bark — what arborists call a "mulch volcano" — traps moisture against the trunk, invites rot, and creates a runway for rodents. Keep it pulled back from the base.

Watering Evergreens Before the Ground Freezes

Broadleaf evergreens like rhododendrons and hollies, and needle evergreens like arborvitae and boxwood, continue to lose moisture through their foliage all winter. When the ground freezes, roots can't replace that moisture. The result is winter burn — brown, desiccated foliage by March.

The fix is simple: water your evergreens deeply in late fall, right up until the ground freezes. One deep, slow soak is worth more than three quick sprinkles. Anti-desiccant sprays (sold at garden centers) add a waxy coating that slows moisture loss and are worth applying to arborvitae and rhododendrons in exposed locations.

Protecting Young Trees from Sunscald and Frost Cracks

Young trees and thin-barked trees — maples, cherries, lindens, honeylocusts — are vulnerable to sunscald. On a sunny winter day, the south and southwest-facing bark heats up, the cells beneath it become active, and then a cloud rolls over and the temperature drops fast. The cells rupture. The result is a vertical crack or a sunken, discolored scar on the trunk, usually on the southwest side.

Tree wrap — the light-colored paper or plastic wrap you see on young trees in winter — reflects sunlight and moderates temperature swings. Wrap from the base up to the first major branch in late November. Remove it in April. Don't leave it on year-round; it creates humidity problems in summer.

The same thin-barked young trees are also targets for deer rubbing and rodent gnawing at the base. Deer rub velvet off their antlers against smooth-barked trees, girdling them. Mice and voles chew bark at ground level, especially under snow cover. Hardware cloth cylinders around the base — buried an inch or two into soil and standing at least two feet high — keep both away.

Salt Spray Damage Near Driveways and Roads

If you have trees within fifteen or twenty feet of a road or driveway that gets salted in winter, you're likely to see salt-related stress by spring. Salt spray deposits on bark and foliage. Salt runoff draws into the root zone and interferes with water uptake. The signs are marginal leaf scorch, premature drop, and die-back on the road-facing side.

A few practical moves:

• Use sand or cinders instead of salt near valuable trees when possible.
• Redirect driveway melt water so it drains away from root zones, not into them.
• Work compost into the soil in early spring to help flush salt through and restore soil structure.

Oaks, spruces, and serviceberries handle salt exposure better than maples, lindens, and dogwoods — worth knowing if you're planning new plantings near a road.

A Word on Ice Storm Emergencies

Central Ohio averages one significant ice storm every two to three winters, and when one hits, calls come in before the ice has stopped falling. Cedar & Oak runs 24/7 storm response because ice damage doesn't wait for business hours. Hanging limbs over roofs, blocked driveways, downed trees on fences — all of it needs to be assessed and cleared safely. Call (555) 234-9100 any time during a storm event.

The homeowners who come through winter with the least drama are the ones who got a structural inspection in November and addressed obvious hazards before the ice arrived.
