Protecting your boxwoods from winter damage and stress is crucial for their survival. Boxwoods are sensitive to extreme temperatures, and prolonged exposure to cold can cause significant damage.
Boxwoods can tolerate temperatures as low as 10°F (-12°C), but prolonged exposure to temperatures below 0°F (-18°C) can cause significant damage.
To prevent damage, it's essential to mulch around the base of your boxwoods. Mulch helps retain moisture and regulate soil temperature.
Mulching also helps prevent soil heaving, which can occur when water freezes and expands in the soil.

In fact, potted boxwoods in a covered unheated greenhouse or shed need to be watered once a month or so while dormant. This helps mimic ideal outdoor conditions.
Mulching
Mulching is a simple yet effective way to protect your plants during winter. Mulching retains soil moisture and acts as a barrier against freezing temperatures.
Using organic materials like wood chips or bark is a great option, applying a depth of 2-4 inches around the base of the plant can make a big difference. This layer of mulch keeps roots cozy and hydrated.
Mulch is particularly important for plants like Velvet Boxwood, which benefits from the protection and moisture retention provided by a well-applied mulch layer.
Winter Protection
Frost can be a formidable foe for Velvet Boxwood, but simple techniques can offer robust protection. Using burlap wraps is an effective method to shield your plants from frost and wind damage.
Applying anti-desiccant sprays can also help reduce moisture loss from leaves. Timing is crucial, so implement these protective measures before the first frost and maintain them throughout the winter months.
Planting windbreaks, such as shrubs, can also make a difference in protecting your Velvet Boxwood from harsh gusts.

Burn
Winter burn can be a real issue for evergreen trees, especially if they're exposed to strong winds and sunny weather, even on cold days. The heat of the sun can cause the stomates on the lower sides of the leaves to open, increasing transpiration and water loss.
Needles and leaves of evergreens always transpire water, even during the winter months. Water loss is increased during periods of strong winds and sunny weather.
The southwest facing side of the plant typically has the most noticeable winter burn damage, especially if the plant has no protection from wind-induced withering. This is because the sun's rays hit this side of the plant directly, causing the stomates to open and increasing water loss.
Desiccation can be severe if the fall has been particularly dry and there is not sufficient moisture to supply the roots adequately during transient ground thawing.

Damage Prevention and Repair
Protecting your boxwoods from winter damage requires some planning ahead. Providing plants with a deep soaking before winter will supply sufficient water to the entire root system and vital parts of the plant before the ground freezes.
Mulching around the base of the plant is a simple yet effective way to prevent damage. Mulch provides an insulation layer that maintains uniform soil moisture around roots, preventing the ground from freezing and able to supply water to the leaves and needles as needed.
Windbreaks made out of burlap, canvas, or similar materials can also help protect your boxwoods from winter damage. By reducing the force of the wind, windbreaks reduce water loss from leaves, keeping your plants healthy and thriving.

Damage Prevention
To prevent damage to boxwood and other evergreens, it's essential to take proper measures during the fall and winter months to protect them from desiccation. This can be achieved by providing plants with a deep soaking before winter, which will supply sufficient water to the entire root system and vital parts of the plant before the ground freezes.
Watering during transient ground thawing on warm winter days also helps to rehydrate plant tissues. This is especially important if fall rain is not sufficient.

Mulching around the base of the plant provides an insulation layer that maintains uniform soil moisture around roots, preventing the ground from freezing and able to supply water to the leaves and needles as needed. This is a simple yet effective way to prevent damage.
Mulch can also prevent frost heaving by buffering alternative freezing and thawing of the soil. Black plastic mulch is not recommended, due to the potential of heat buildup during sunny periods.
Windbreaks made out of burlap, canvas or similar materials protect boxwoods and other small evergreens by reducing the force of the wind, thereby reducing water loss from leaves.
Damage Repair
April is the perfect time to prune boxwood plants, as they haven't started to sprout new growth.
Pruning away damaged parts of the plant helps it recover from winter burn. To repair the plant, cut the tips of any damaged branches just above a living, green leaf.

Use shears for smaller branches and loppers for large branches that are larger than an inch in diameter. This will make way for healthy, new growth.
Consider establishing boxwood and other evergreen plants that are suitable to your hardiness zone for ease of maintenance and long-term prevention of winter burn damage.
Anti-transpirant and anti-desiccant garden sprays can help retain moisture and prevent water loss. These compounds are sprayed directly onto the plant and can also protect plants from some fungal diseases.
If leaves turn brown or tan after proper pruning, it's possible the plant is suffering from a fungal leaf disease. Common symptoms include brown discoloration and presence of black fungal fruiting structures on leaves.
Establishing a mulched area around the tree trunk usually eliminates damage caused by mowers and weed trimmers. A 2- to 3-foot radius is usually sufficient to protect the tree.

Growing Indoors
Growing indoors can be a challenge, especially for plants that need a dormant period. Boxwoods, for instance, require a rest period to recharge during the winter, which they won't get inside your home.
You can still care for your potted plants, but be mindful of their watering needs. Water them through late fall and no more than once a month through the winter.
Removing large or heavy snow accumulation from your plants is essential to prevent damage.
Spring Recovery

As the last wisps of winter fade, it's time to give your Velvet Boxwood a spring boost. Timing is crucial, so aim to prune your plant from late winter to early spring, just before new growth begins.
Removing dead or damaged branches is essential for promoting healthy growth. This simple step can make a huge difference in your plant's overall health.
Shaping your Velvet Boxwood can also improve airflow, which is vital for its rejuvenation. By doing so, you'll create a more balanced and thriving plant.
