Protecting Evergreen Plants from Winter Wind

When winter temperatures drop, cold alone isn’t always what causes the most damage to evergreen plants. In fact, windchill is often the bigger threat. Cold, dry winds can pull moisture from leaves at a time when frozen soil prevents roots from replenishing it, leading to winter burn and stressed tissue.

Evergreen plants keep their foliage year-round, so they continue photosynthesizing during winter, even if growth is minimal. That’s why completely covering plants with opaque materials for an extended period of time can sometimes do more harm than good, depriving them of light while trapping moisture and limiting airflow. This concern is specific to evergreen plants, since deciduous plants drop their leaves in winter and are far less vulnerable to wind-driven moisture loss.

When Winter Protection Is Most Helpful

Extra protection is most beneficial for evergreen plants that are:

• Exposed to strong winter winds, especially during freezing temperatures
• Planted in open or elevated sites
• Newly planted or not yet well established
• Broadleaf evergreen plants, which lose moisture more readily than needle-leaved evergreens

Sheltered plants, mature specimens, or those naturally adapted to harsh conditions often need little to no intervention.

Our Light-Friendly Technique for Short Freezes

One practical technique that was passed down to us by Jack Olson involves a simple solution using just water. During short periods of freezing weather, lightly running a sprinkler or hose over susceptible evergreen plants can create a thin layer of ice that acts as a temporary wind barrier. Ice is translucent, which allows light to reach the foliage, while helping stabilize tissue temperature and reducing moisture loss from harsh winds.

This approach works best during brief cold snaps, particularly for wind-exposed plants, and isn’t intended for prolonged deep freezes or already stressed plants. As with most winter care, the goal isn’t insulation — it’s protection from dehydration and wind exposure.

For Regions with Prolonged Freezing

In regions that experience prolonged periods below freezing, breathable wind barriers such as burlap or fabric enclosures are often a better long-term solution, offering consistent protection without restricting light or airflow. The best options typically use rigid framing, providing a structure that can hold up against various winter conditions. See the image below for an example.

When winter weather turns challenging, thoughtful protection can make a meaningful difference, helping evergreens emerge healthier when spring arrives. We love sharing this guidance to help ensure evergreen plants remain healthy through the winter season.
