What Is Burlap Tree Protection and How Does It Work? | The Winter Essential

Burlap tree protection uses a breathable fabric wrap to shield trunks and evergreens from winter threats like sunscald, frost cracks, and deer damage without trapping heat or moisture.

A deep freeze cracks your prized maple’s trunk come February. A sudden late-winter sun scorches the south side of a young poplar until the bark splits open. These aren’t bad luck — they are predictable winter injuries, and a roll of untreated burlap is the cheapest, most effective weapon against them. The fabric blocks direct sunlight and harsh wind while letting air and water pass through, so the tree stays protected without sweating under a plastic seal. The method takes about ten minutes per tree, costs around forty dollars per roll, and can save you from replacing a damaged ornamental come spring. If you are already shopping for supplies, our tested roundup of the best burlap tree protection options lays out the top rolls, stakes, and kits side by side.

Burlap Tree Protection Defined: One Fabric, Four Jobs

Untreated burlap wrap protects trees against four distinct winter enemies: sunscald, desiccation, frost cracking, and animal damage. Sunscald happens when winter sun warms the bark on a sunny day, then temperatures plunge at night — the freeze-thaw cycle kills cambium tissue and leaves vertical cracks. Burlap shades the trunk so it stays at a stable temperature. Winterburn (desiccation) hits evergreens when frozen ground prevents roots from replacing water lost to wind and sun. A loose burlap screen cuts wind speed around the foliage without sealing moisture in. Frost cracking works like sunscald but from the inside out — rapid temperature swings cause the trunk’s outer wood to contract faster than the inner wood. Burlap insulation moderates that swing. And for deer, rabbits, and voles that gnaw bark in lean winter months, burlap is a physical barrier that doesn’t become a chew toy like plastic wraps can.

Which Trees Actually Need Burlap Wrapping?

Not every tree needs it. Established, thick-barked species like oaks and hickories shrug off winter. The trees that benefit are young, thin-barked, or newly planted: species where the cambium is still vulnerable and the root system is too shallow to fight winter alone. The table below shows the candidates.

Burlap-Worthy Trees At A Glance

Two Methods That Work: Direct Wrap vs. Stake Screen

Which method you choose depends on the tree and the threat. Direct wrapping works for evergreen foliage that needs wind and sun protection. A stake-and-burlap fence is better for Japanese Maples and any tree where you want air circulation around the trunk.

Method 1: Direct Wrap For Evergreens (Arborvitae, Cedar)

This method takes one person and about five minutes per tree. Start at the lowest branches and work upward, wrapping loosely enough that the fabric doesn’t snap twigs. Stop slightly above the highest peak. Pin the burlap with staples or nails temporarily, cut the roll, and remove the pins. Then tie garden twine at the top, middle, and bottom — start at the top and work downward so you don’t push branches inward.

Method 2: Stake Screen For Japanese Maples And Exposed Specimens

Drive three wooden stakes into the ground around the tree in a triangle — one on the wind-exposed side, one in front, and one on the opposite side. Keep stakes about 1.5 to 2 feet from the trunk so air moves freely. Stretch burlap across the stakes and secure it with stainless steel staples (regular staples rust in winter and snap). Overlap the layers so there are no gaps at top or bottom, then add twine at the corners for extra hold. This creates a windbreak without pressing fabric against the bark, which is critical for Japanese Maples that rot under direct contact.

When To Wrap And When To Unwrap

Temperature swings kill trees. So does leaving the wrap on too long. The timing matters as much as the fabric.

Wrap In Late Fall

Apply burlap just before the first hard frost — typically around Thanksgiving for the Northeast and Midwest US, or whenever the ground starts to freeze. If you wrap too early in October when the soil is still warm, you can trap heat around the trunk and confuse the tree’s dormancy cycle.

Remove By Early Spring

Take the wrap off when the ground thaws and temperatures stay above freezing — Easter weekend is the traditional benchmark. Leaving burlap on through summer invites insects, mold, and rodents that nest between the fabric and the bark. The tree needs that airflow during the growing season.

Common Mistakes That Turn Protection Into Damage

The most expensive mistakes come from good intentions applied wrong. Wrapping too tight is the worst — it breaks branches when the wind rocks the tree, and it can girdle the trunk as the tree grows. Using plastic sheeting instead of burlap is another: plastic traps solar heat during the day, then lets cold air hit the bark at night, which makes sunscald worse. Skipping spring removal is the third: by June, a wrapped trunk is a dark, humid incubator for borers and fungal disease. And on Japanese Maples, wrapping the branches directly instead of building a stake screen cuts air circulation and leads to rot in the crotches where branches meet the trunk.

The Right Product For The Job

Not all burlap is the same. The roll you want is labeled untreated and made from 100% natural jute or hemp. Treated burlap may contain chemicals that leach into the bark or fumigate beneficial soil organisms. A standard roll is 4 inches wide and 300 feet long — that is enough to wrap about a dozen young trees or build three stake screens. The cost runs between $35 and $45 per roll, which usually beats buying individual tree wraps for each specimen.

Winter Prep Checklist: What To Do Beyond The Wrap

Burlap is not magic. It works best when you pair it with two other fall chores. First, water deeply before the ground freezes — evergreens go into winter starved for water, and a good soak in November reduces winterburn more than any wrap does. Second, apply a 2-to-3-inch layer of mulch around the root zone (not against the trunk) to insulate the roots and delay soil freezing so the tree can pull up moisture longer. Third, if deer are your main problem, wrap burlap higher than the browse line — deer stand on hind legs and can reach 6 feet up. Fourth, for salt spray from roads or de-icing runoff, a burlap screen on the roadside is more effective than wrapping the whole tree.
