How to Wrap a Tree with Burlap for Winter Protection | Loosely Spiral & Stake Methods

Winterizing a tree with burlap requires one of two methods—a loose spiral wrap around the trunk or a staked windbreak fence—each designed to shield sensitive bark and evergreen foliage without trapping moisture or restricting airflow.

A single hard freeze can split a young maple’s thin bark or desiccate an arborvitae so thoroughly it turns brown by January. The people who swear by burlap aren’t using it as a blanket; they are using it as a windbreak with a deliberate air gap, and the difference between protection and damage is in the execution. Here is exactly how to do both methods right, the materials that won’t hurt your tree, and the common errors that turn a winter wrap into a death sentence.

What Burlap Actually Does for a Tree in Winter (And What It Doesn’t)

Burlap’s real job is to stop winter wind from stripping moisture out of evergreen needles and to prevent sun scald on thin-barked trunks. It does not keep the tree warm—in fact, a snug wrap that eliminates the insulating air layer between fabric and bark does more harm than no wrap at all. The material breathes, which means moisture from snow and condensation can evaporate rather than pool against the bark where it would feed fungi. Plastic sheeting blocks that evaporation entirely and rots the tree from the outside in.

When to Wrap and When to Unwrap

Timing is the variable that separates an effective winter prep from a springtime surprise. Wrap after the first hard frost—typically late November for most US climates—once the tree is fully dormant and the ground has begun to freeze. Wrapping before dormancy traps warmth and tricks the tree into staying active, which makes it vulnerable when the real cold arrives. Remove the burlap in mid-to-late March or when daytime temperatures consistently reach 40°F and the last hard frost has passed. Leaving the wrap on past that point traps heat as the tree tries to exit dormancy and creates a steam-bath environment that stresses the bark and fuels fungal growth.

Materials: What to Buy and What to Skip

Natural jute burlap is the only material that should touch your tree. A standard roll covering roughly 100 square feet runs between $20 and $40 depending on width and density. For the windbreak method, 4-to-5-foot wooden stakes cost $2 to $5 each, and you will need three for a triangle arrangement or four for a square in windier sites. Natural jute twine is the correct tie; soft fabric garden ties work too. Avoid thin wire, metal tape, or any plastic-coated tie—these cut into bark as the trunk sways and create girdling wounds that can kill a branch or the whole tree over the course of one winter. Fishing line is a specific and valid exception for keeping upright evergreens from leaning under heavy snow, but use it only on the outside of the burlap, never against bare bark.

Method A: Loose Spiral Wrap for Young Trunks and Thin-Barked Species

This method is best for young trees, newly planted trees (which need at least two winters of protection), and species like maple, birch, beech, or any tree with smooth, thin bark. The spiral wrap prevents sun scald—the cracking that happens when winter sun warms the bark during the day and temperatures crash at night.

1. Prepare the tree in late fall. Water the soil thoroughly before it freezes so the roots go into winter hydrated. Prune only damaged or crossing branches—heavy pruning stimulates new growth at the wrong time. Treat any active pest issues before wrapping.
2. Start at the base just above the soil line. Wrap the burlap around the trunk snugly but not tight. The fabric should touch the bark without compressing it.
3. Spiral upward, overlapping each wrap by roughly one-third of the burlap’s width as you go. For small evergreens, continue spiraling over the lower branches to cover the base of the foliage. Do not pull the material taut as you go.
4. Secure in three places—bottom, middle, and top—with jute twine. Attach the twine snugly enough to hold the wrap in place against wind, but stop short of pulling the burlap tight against the bark.
5. Confirm the air gap. You should be able to slide a finger easily between the burlap and the trunk at any point. If you cannot, the wrap is too tight and needs to be loosened immediately. The layer of still air between fabric and bark is what does the insulating; compressing it is the exact mistake that causes winter dieback.

Method B: Staked Windbreak Fence for Harsh Sites and Evergreens

This is the better choice for evergreens like cedars, arborvitae, yews, and spruce that suffer more from wind desiccation than from cold itself. It is also the go-to method for exposed sites where wind blasts directly across open ground. The windbreak fence stops the wind but leaves the tree fully exposed to light and air exchange, which matters because evergreens continue to transpire through winter.

1. Place the stakes in a triangle or square around the tree, roughly 12 to 16 inches away from the outermost branches. One stake goes on the prevailing-wind side, one opposite it, and the third completes the shape. In very harsh sites, four stakes create a square that captures wind from more angles.
2. Stretch burlap around the stakes and staple it firmly so the fabric holds against winter gusts. Use a heavy-duty staple gun—the wind will test every staple.
3. Leave the top fully open. This is not optional. A sealed top traps moisture, blocks snowmelt evaporation, and stops the tree from shedding heat on sunny winter days. Open tops release that moisture and allow the tree to breathe.
4. Check the gap. No part of the burlap should touch any branch. If wind blows the material against the tree, widen the stake ring or tighten the burlap across the stakes. Burlap freezing to a branch is as damaging as no protection at all.

Six Mistakes That Turn Wrapping Into Damage

The same errors show up every winter in extension-office reports and nursery forums. These are the ones to watch for on the first windy day after the temperature drops.

• Wrapping too tight compresses the bark and breaks the cambium layer, which mangles the tree’s vascular system and produces a girdling wound that looks like a scar for years.
• Direct contact without an air gap lets the burlap freeze to the bark. When the wind blows, the frozen fabric tugs at the bark and tears it. That gap is not a nice-to-have—it is the entire point of the method.
• Using plastic or synthetic fabric creates a sealed moisture pocket. Fungal mycelium spreads rapidly inside that dark, wet envelope, and by March the bark is rotten or cankered.
• Wire or tape ties slice through bark on a windy day. The tree cannot heal a full-circumference girdle below the first branch, and the top dies slowly over one or two growing seasons.
• Covering the top on a staked fence blocks airflow and traps humidity. The tree suffocates in its own transpiration and develops mold on the needles or branches.
• Leaving the wrap on past mid-March overheats the bark, stimulates premature growth, and then a late freeze kills that tender new tissue. Remove burlap when daytime temperatures reliably hit 40°F and frost is no longer forecast.

Inspection and Maintenance Through the Winter

Burlap is not a set-it-and-forget-it solution. Check the wrap after the first heavy snow and after every windstorm that exceeds 30 mph. Tighten any loose staples or twine, but recut the same rule: snug is fine, compressed is not. If the burlap has blown against a branch, reposition the stake or replace the fabric. Also check soil moisture during dry stretches in January and February—burlap reduces wind-driven evaporation but does not water the tree. If the ground is not frozen and the soil is dry at a knuckle’s depth, give the tree a slow soak.

Which Trees Actually Need Burlap Protection?

How to Wrapped a Tree for Winter Protection: Final Checklist

Before the ground freezes hard, run through this sequence. Wait for the first hard frost. Select natural jute burlap and jute twine. Measure your stakes and position them 12 to 16 inches from the branches. For the spiral method, wrap from base to top with a loose layer and an air gap you can feel with a finger. For the stake method, staple the burlap to the posts and leave the top open. Secure with twine in three spots or staple firmly. Check after the first wind event. Remove in mid-to-late March when temperatures hit 40°F. The tree that gets this treatment enters spring with intact bark, green needles, and no fungal scars to heal in the growing season ahead.
