Broadleaf evergreens can lose moisture through their leaves while frozen soil limits what their roots can replace. In an exposed spot, a burlap screen can reduce the force of winter wind and the intensity of sun. Think of it as a seasonal barrier around the shrub, not a tight coat tied directly to the foliage.

1. Decide whether the site needs a screen

Start with the south, southwest, and windward sides, where winter exposure is often strongest. Newly established boxwood, rhododendron, holly, and similar evergreens may benefit most. Water appropriately through fall until the ground freezes, because fabric cannot correct an already dry root zone.

2. Set supports beyond the branches

Drive sturdy stakes outside the shrub's drip line while the soil is workable. Leave room between the supports and foliage so snow-laden material will not rub leaves or bend twigs. A three-sided screen may be enough for one exposed direction; surround the plant only when the whole site is open.

3. Fasten the burlap without sealing the plant

Attach a breathable garden burlap roll to the stakes with weather-suitable ties or staples. Keep the top open for light and air, and hold the bottom securely without packing leaves inside. The goal is to interrupt wind, not create a damp enclosure.

4. Check it after rough weather

After strong wind or heavy snow, retighten loose fasteners and lift sagging sections away from the shrub. Watch for pooled moisture, animal activity, or ties pressing into stems. Remove the barrier promptly when persistent hard-freeze conditions ease in spring, following local guidance.

Before the first frost

• Water based on soil conditions before freeze-up.
• Place stakes clear of branches and roots where possible.
• Leave the top open and keep burlap off the foliage.
• Plan a spring removal reminder now.
