Removing Snow Load from Evergreens Safely

Every January I get the same panicked phone call. A homeowner walks outside after a wet six-inch snow, sees their arborvitae or upright juniper splayed open like an unfolded book, and wants to know if they should grab a broom and start whacking. The answer is yes, sometimes, and no, sometimes, and the difference between the two costs people their hedges every winter across Central Ohio.

I’ve been pruning and shaping evergreens in Pickaway, Franklin, and Fairfield counties for more than ten years, and snow-load damage is one of the most preventable problems I see. Most of it comes down to acting at the right time with the right tool.

When should I knock snow off evergreens, and when should I leave it alone?

Knock the snow off while it’s still soft and wet, ideally within the first few hours after a heavy snowfall ends. Once the snow has frozen onto the branches, leave it alone and wait for a thaw. That’s the rule I work by on my own client properties and the rule that prevents most of the broken leaders and split trunks I get called to evaluate in February.

A wet, heavy snow load on a six-foot arborvitae can weigh more than the tree itself. The branches splay outward under that weight, and if temperatures drop fast and the load freezes in place, you’ve got hours, not days, to make a decision. Hit it gently with an upward sweep of a soft broom while it’s still wet, and the branches snap back to vertical with no damage. Wait until the next morning when the load has glazed over, and one wrong swing will snap a branch off at the trunk.

On a Lancaster property I serviced last winter, the homeowner waited until afternoon to address a heavy morning snow. By the time I got there at 2 p.m., the temperature had dropped from 31 to 22 and every branch was rigid. We left it alone, waited for the thaw two days later, and the arborvitae bounced back ninety percent. The one branch the homeowner had tried to free with a rake on the second morning split clean off the leader. That’s a $400 replacement once you factor in removal and a matching B&B from the wholesale yard.

What tool should I use to remove snow from evergreens?

A soft-bristle push broom or a long-handled foam paint roller is what I use, and what I tell my clients to keep by the back door from December through March. Nothing rigid. No rakes, no shovels, no snow brushes off a truck windshield. The bristles need to flex against the foliage without transferring impact to the branch wood underneath.

The motion matters too. You sweep upward from below the branch, lifting the snow off the way you’d brush a coat sleeve, not downward like you’re chopping. Downward strokes drive the load further into the canopy and can snap interior branches you can’t even see.

For taller evergreens over about seven feet, I use a telescoping pole with a soft head, the kind painters use for ceiling work. If you can’t reach a branch from the ground with a pole, leave it. Ladders on snow-covered ground are how people end up in the Pickaway Memorial ER on a Saturday morning. I won’t put one of my own crew on a ladder for snow removal, and I don’t recommend it for any homeowner.

Which evergreens are most vulnerable to snow load damage?

Upright arborvitae, columnar junipers, and the narrow ornamental cultivars take the worst of it because their natural form is exactly the form that splays under weight. Emerald Green, Degroot’s Spire, and Skyrocket junipers are the three I get the most calls about across Pickerington and Canal Winchester subdivisions.

Spruce and pine handle snow load reasonably well because their branches angle downward naturally, shedding most of what falls. White pine is the exception. Mature white pines develop horizontal branching that catches and holds wet snow, and I’ve seen white pine branches the diameter of my forearm tear off in a single heavy storm. If you’ve got a mature white pine within fall distance of your driveway or roof, that’s a tree to keep an eye on.

Boxwood and yew, technically broadleaf evergreens, hold snow well and rarely need intervention unless a branch is touching the ground or pinned under accumulated drift. The bigger risk on boxwood is the salt spray off the road, which is a different problem we’ll cover in another post.

Should I tie up my arborvitae before winter to prevent damage?

Yes, for any upright multi-stem evergreen over four feet tall in a location prone to wind-driven snow. This is one of the cheapest preventive moves you can make, and it’s the one most homeowners skip.

In late November on my client properties, we run a single wrap of soft jute twine in a spiral from base to top on multi-stem arborvitae and upright junipers. The twine pulls the stems together just enough that snow slides off rather than pries them apart. It comes off in March before bud break. Total time on a typical six-foot arborvitae is about three minutes. Total cost in materials is under a dollar.

Don’t use plastic strap or wire. Both will girdle the bark over a winter and leave permanent damage. Don’t pull the wrap tight enough to deform the shape, just snug enough to keep the stems from flexing wide. And don’t leave it on past mid-March or you’ll suppress the spring flush.

If you missed the November window and want to address it now in January, you can still wrap, but do it on a thaw day when the branches are flexible. Wrapping frozen, snow-laden branches is how people break the very trees they’re trying to save.

What do I do if a branch has already broken?

Leave the broken branch alone until late February or early March, when you can make a clean cut at the proper location. Tearing off a hanging branch in January creates a wound the tree can’t seal because it’s dormant, and that opens the door to disease entry once the sap starts moving.

The exception is a branch that’s a hazard to people, pets, or property. If a torn limb is dangling over a walkway or pulling a power line, that gets addressed immediately. Everything else waits.

When you do make the cut in March, find the branch collar, that slight swelling where the branch meets the trunk, and cut just outside it. Don’t cut flush. Don’t leave a long stub. The collar is what the tree uses to seal the wound, and a cut in the wrong place can take three years to close, if it ever does.

For larger branches over about two inches in diameter or for any cut you can’t make from the ground safely, that’s an arborist call, not a homeowner call. I do small ornamental hedge and tree work myself, but for mature canopy work I refer to certified arborists I trust in the Central Ohio area.

How does road salt and plow throw interact with evergreen damage?

If your evergreens line a street or driveway, snow load isn’t your only concern. Plow throw piles salt-saturated snow directly onto the foliage, and the salt burns the needles and scales as it melts. The damage shows up in March as bronzing on the road-facing side of the plant.

On a Grove City commercial property I maintain, the front-row arborvitae against the parking lot edge took heavy salt damage two winters ago. We rinsed them down with a garden hose during the first March thaw, leached the soil, and they recovered. The trick is acting before bud break.

For more on salt damage and how to mitigate it, see our companion post on road salt runoff and landscape damage. The two problems often show up on the same plants in the same winter.

Quick evergreen snow-load checklist for Ohio winter

• Keep a soft push broom and a long foam pole by the back door from December to March
• Address heavy wet snow within hours, before it freezes
• Sweep upward from below, never downward
• Skip ladders and rigid tools entirely
• Wrap upright multi-stem evergreens with jute twine each November
• Leave broken branches until March for proper cuts
• Rinse salt-damaged foliage during the first thaw
