They are low-maintenance and, being resistant to deer and rabbits, many boxwoods thrive in growing zones 4-9.
However, as evergreens, it’s a known fact that they aren’t particularly hardy in the face of extreme cold.
Winter burn, a common woe for boxwoods, manifests in slight discoloration such as bleached or necrotized leaves.
Fortunately, it’s typically not a major issue.
Despite losing affected leaves, the bush generally pulls through for another winter, unless the burn is severe or the bush is young.
However, recurrent incidents over several years might result in lasting damage.
But this is the story for Boxwood grown in the ground.
Can Boxwood Survive Winter in Pots?
Absolutely! Growing them in containers puts you ahead in winter care, but it comes with its own set of rules.

Boxwoods in pots require regular watering, especially before freezing weather hits.
Since container water can’t be absorbed when frozen, they rely on stored water in stems and leaves to survive winter.
To prevent breakage under heavy snow, wrap them in burlap or plastic wildlife netting.
Mulch with wood chips or leaves, avoiding snow accumulation on top.
Also, steer clear of placing them under building eaves prone to frequent snowfall.
Here are what I usually do in more details:
Mulching
To help insulate the soil and protect the roots from extreme temperature fluctuations, you can apply a 2-3 inch layer of organic mulch, such as shredded bark or compost, around the base of the boxwoods. Avoid piling the mulch against the main stem.
Windbreaks
If your region experiences strong winter winds, consider planting boxwoods near structures or using burlap screens to create a windbreak and shield the shrubs from harsh conditions.
Watering
While boxwoods are typically hardy, ensuring sufficient moisture before the ground freezes is extremely important for their winter survival.
Ample hydration before the onset of cold temperatures is the key to helping boxwoods endure winter. My usual approach:
- Water the boxwoods deeply before the ground freezes. Ensure they receive at least one inch of water per week, including precipitation.
- If heavy snow accumulates on boxwoods, gently brush it off with a broom to prevent branches from breaking under the weight.
Boxwood Frost Damage
Like I mentioned, your boxwood might exhibit signs of winter burn, showcasing brown or bronze leaves, giving the appearance of distress.

However, in most cases, they tend to rebound with vitality and vibrancy as temperatures rise, particularly when you can still observe some green leaves on the branches.
Conversely, if the entire shrub turns pale yellow and lifeless, there’s a high likelihood that the boxwood may have succumbed to the harsh winter.
To confirm, a reliable method is to scrape a piece of bark or even cut a tip or two to inspect for green living tissue.
Conclusion: Boxwood can survive winter in pots or garden beds

Moreover, the hardiness of boxwoods extends to their ability to endure winter conditions, whether in pots or garden beds.
These resilient shrubs exhibit remarkable cold tolerance, providing year-round visual interest even in colder climates.
