How to Wrap Shrubs for Winter Protection: Burlap, Windburn & Timing

Winter damage to shrubs usually is not caused by cold alone. The real villains are drying winter wind, harsh winter sun on frozen foliage, the crushing weight of snow and ice, and road salt spray. Evergreens are especially vulnerable because they keep their leaves and keep losing moisture through them all winter, even as frozen soil makes it impossible for the roots to replace that water. The result is “windburn” or “winter burn,” the browning and desiccation you see in spring. Wrapping shrubs with burlap is the time-tested defense. Done correctly and at the right time, it shields plants from wind, sun, snow load, and salt without smothering them. Done wrong, it can do more harm than good. This guide covers when to wrap, which shrubs need it, exactly how to do it, and the mistakes to avoid.

Why Shrubs Need Winter Protection

Understanding the mechanism tells you what wrapping actually protects against. The biggest threat to evergreen shrubs is desiccation. Their leaves and needles continue to transpire, losing water vapor, throughout winter. On a bright, windy, sub-freezing day, that water loss accelerates, but the roots cannot pull replacement water from frozen soil. The foliage effectively dries out, turning brown, bronze, or scorched, usually on the windward and south or southwest sides that catch the most sun and wind. This is winter burn, and it is a moisture problem, not a freezing problem.

The other threats are mechanical and chemical. Heavy, wet snow and ice accumulate on multi-stemmed and upright shrubs like arborvitae and junipers, splaying or snapping branches under the load. Road salt, whether splashed from traffic or carried as spray, draws moisture out of foliage and damages buds and bark on shrubs near driveways and streets. Wrapping addresses all of these at once: it breaks the wind, shades the foliage from intense sun, supports branches against snow load, and forms a physical barrier against salt spray.

When to Wrap (Timing Is Critical)

The timing rule is simple and important: wrap late, unwrap late. Wrap only after the shrub has fully hardened off for winter and the ground has begun to freeze, generally late fall to early winter once you have had several hard frosts. Wrapping too early, while the plant is still in mild fall weather, traps warmth and moisture, which can encourage soft late growth, invite rot and disease, and prevent the plant from properly acclimating to cold. You want the shrub dormant and cold-adjusted before it goes under wraps.

On the other end, do not rush to unwrap in the first warm spell of late winter. The drying winds and bright sun of late winter and early spring, while the ground is still frozen, are often the most damaging conditions of all. Leave the wrap on until the threat of hard freezes and harsh wind has reliably passed and the ground has thawed, usually early to mid spring. Remove it gradually so the foliage re-acclimates to direct sun. This same late-wrap, late-unwrap logic applies to other tender plants you protect, including the approach in our guide to winterizing a fig tree.

Which Shrubs to Prioritize

Not every shrub needs wrapping, and over-wrapping a tough, fully hardy deciduous shrub is wasted effort. Focus your burlap where it counts.

• Broadleaf evergreens: boxwood, holly, rhododendron, azalea, and laurel are the most prone to winter burn because of their large, moisture-losing leaves.
• Needled evergreens in exposed spots: arborvitae, yews, and junipers, especially young ones or those on windswept or south-facing sites.
• Newly planted shrubs: anything planted in the last year or two has a small root system and far less resilience, regardless of species.
• Tender or borderline-hardy shrubs: varieties at the edge of their hardiness zone.
• Shrubs near roads, driveways, and walkways: these face salt spray and need a barrier.
• Upright multi-stemmed evergreens: columnar arborvitae and similar that splay under snow benefit from wrapping that also ties the form together.

Fully dormant, hardy deciduous shrubs generally do not need wrapping; they drop their leaves and stop transpiring, so winter burn is not a concern. A heavy mulch over the roots is usually enough for those.

How to Wrap Shrubs With Burlap, Step by Step

Burlap is the standard for good reason: it blocks wind and reduces sun while remaining breathable, so heat and moisture do not build up inside. There are two common approaches, a wrap directly around the plant or a windbreak screen, and you can combine them.

1. Water and mulch first. Before the ground freezes, give the shrub a deep, thorough watering, a well-hydrated plant resists desiccation far better, and lay 2–4 inches of mulch over the root zone to insulate the roots and conserve soil moisture.
2. For the direct wrap, build a frame for tall or vulnerable shrubs. Drive three or four wooden stakes into the ground around the shrub. The frame keeps the burlap off the foliage so it is not pressing wet fabric against the leaves.
3. Wrap the burlap around the frame (or the shrub), spiraling from the bottom up. Overlap each pass and keep it snug but not tight. Secure it with twine, jute, or staples to the stakes. Leave the very top open for air circulation unless you are specifically guarding against snow load from above.
4. For a windbreak screen, stake burlap on the windward and sunny sides only. This is often enough for shrubs that mainly need protection from prevailing wind and south or southwest sun, and it lets the plant breathe freely.
5. For salt protection, make sure the barrier faces the road or driveway and extends low enough to block splash and spray.
6. For snow load, gently tie up the branches first with soft twine in a spiral before wrapping upright shrubs, so they cannot splay, then wrap over the top.

Mistakes to Avoid

The most damaging mistake is using plastic instead of burlap. Plastic is airtight: on a sunny winter day it traps heat and bakes the plant, and it holds moisture against the foliage, causing rot and disease. Always choose a breathable material. The second mistake is wrapping too tightly or too early, which suffocates the plant, encourages disease, and prevents proper cold acclimation. Wrap snugly, not constricting, and only after the plant has hardened off. The third is pressing wet burlap directly against foliage, which is why a stake frame is preferable for sensitive evergreens. Finally, do not forget the basics, wrapping is a supplement to, not a replacement for, deep fall watering and root mulching, which are the foundation of winter survival.

Alternatives to Wrapping

Wrapping is not the only tool. Anti-desiccant sprays, waxy coatings applied to evergreen foliage in late fall, slow moisture loss and can reduce winter burn, though they need reapplying and are best for plants you would rather not wrap. Permanent burlap or snow-fence windbreaks shelter whole groups of shrubs. Choosing the right plant for the right place, putting tender evergreens in sheltered spots rather than windswept corners, prevents the problem entirely. And for many gardeners, the simplest long-term answer is to favor hardy, wind-tolerant species in exposed locations so wrapping becomes unnecessary.
