Will Boxwoods Grow In Colorado

Boxwoods will grow in Colorado, but it takes some planning and care.
 
If you’ve been dreaming of classic, evergreen hedges or tidy foundation plants, you’re probably wondering if boxwoods will grow in Colorado.
 
The short answer is yes—boxwoods will grow in Colorado, but not every variety thrives in our unique climate.
 
Colorado presents challenges like intense sun, drying winter winds, altitude, and rapid temperature swings.
 
Still, with the right variety, proper planting, and winter protection, you can successfully grow boxwoods in Colorado.
 
In this post, we’ll cover exactly why boxwoods will grow in Colorado, the best ways to plant and care for them, and the common hurdles you’ll face.
 
Let’s dig in.

Why Boxwoods Will Grow in Colorado

Boxwoods will grow in Colorado because several cold-hardy cultivars are well suited to our conditions.
 
Here’s what makes it possible:

1. Cold-Hardy Boxwood Varieties

The first reason boxwoods will grow in Colorado is that certain varieties are bred to survive cold winters.
 
Look for cultivars like ‘Green Mountain’, ‘Green Velvet’, ‘Winter Gem’, and ‘Chicagoland Green’.
 
These boxwood varieties for Colorado are rated to USDA zones 4–5, which covers most of the state.
 
‘Green Mountain’ holds its dark green color well and handles cold temperatures down to -30°F.
 
Choosing a cold-hardy boxwood variety is the number one factor for success when growing boxwoods in Colorado.

2. Colorado’s Microclimates Work in Your Favor

Colorado isn’t one uniform climate—it’s full of microclimates that help boxwoods grow in Colorado.
 
A south-facing slope, a spot near a building, or a sheltered courtyard can be warmer than the rest of your yard.
 
These microclimates reduce winter wind exposure and reflect heat, making it easier for boxwoods in Colorado to survive.
 
If you plant boxwoods in Colorado near a brick wall or fence, they’ll benefit from extra warmth and protection.

3. Proper Winter Protection Boosts Survival

Even with a hardy variety, boxwoods will grow in Colorado only if you provide winter protection.
 
Winter burn is the biggest threat—caused by cold winds and bright sun drying out evergreen leaves.
 
Wrapping shrubs with burlap or using anti-desiccant sprays in late fall helps boxwoods grow in Colorado successfully.
 
Applying a thick layer of mulch around the base also insulates roots from freeze-thaw cycles.

How to Successfully Grow Boxwoods in Colorado

Knowing that boxwoods will grow in Colorado is one thing—actually making it happen requires the right method.
 
Follow these steps to help boxwoods in Colorado thrive:

1. Choose the Right Planting Site

When you’re growing boxwoods in Colorado, site selection matters more than in milder climates.
 
Pick a spot with partial shade—especially protection from harsh afternoon sun in winter.
 
Avoid low-lying areas where cold air settles, as frost pockets can damage boxwoods in Colorado.
 
Also ensure the soil drains well because boxwoods hate wet feet, and Colorado’s heavy clay can cause root rot.

2. Plant at the Right Time

The best time to plant boxwoods in Colorado is spring, right after the last frost.
 
Spring planting gives roots a full growing season to establish before winter arrives.
 
Fall planting is riskier because boxwoods in Colorado need time to root before the ground freezes.
 
If you must plant in fall, do it at least six weeks before the first hard freeze.

3. Water Deeply and Mulch Well

Boxwoods in Colorado need consistent moisture, especially during their first two years.
 
Water deeply once a week—more if the weather is hot and dry.
 
Apply 2–3 inches of organic mulch like wood chips or pine bark around the root zone.
 
Keep mulch a few inches away from the trunk to prevent rot, but let it cover the roots completely.
 
This mulch helps regulate soil temperature and holds moisture, helping boxwoods grow in Colorado.

Common Challenges When Growing Boxwoods in Colorado

Even though boxwoods will grow in Colorado, you’ll encounter a few obstacles.
 
Here are the most common ones and how to handle them:

1. Winter Burn and Leaf Desiccation

Winter burn looks like brown or yellow patches on leaves, usually on the south or west side.
 
It happens when frozen ground prevents roots from taking up water, but the sun and wind keep drying the leaves.
 
To prevent winter burn when you grow boxwoods in Colorado, apply an anti-desiccant spray in late November.
 
You can also erect a burlap screen or shade cloth to block drying winds.

2. Snow Load and Branch Breakage

Heavy Colorado snow can bend or break boxwood branches.
 
To avoid this, gently brush snow off branches after a storm—don’t shake them, as brittle stems snap easily.
 
Prune your boxwoods in Colorado to an open shape that doesn’t trap snow.
 
Using a snow fence or planting in a spot where drifts don’t accumulate also helps.

3. Pests and Diseases

Boxwoods in Colorado can face boxwood leafminer, psyllids, and mites.
 
Inspect leaves for blisters or stippling in spring.
 
Horticultural oil or insecticidal soap usually controls these pests.
 
Boxwood blight is rare in Colorado’s dry climate, but avoid overhead watering to keep foliage dry.

So, Will Boxwoods Grow in Colorado?

Boxwoods will grow in Colorado.
 
But the process isn’t just a simple dig-and-plant affair.
 
With the right cold-hardy variety, a sheltered planting site, and consistent winter protection, your boxwoods in Colorado can thrive for years.
 
Remember, growing boxwoods in Colorado takes a little extra effort, but the lush evergreen structure is worth it.
 
If you pick a variety like ‘Green Mountain’ or ‘Green Velvet’ and follow the care tips above, you’ll have beautiful boxwoods in Colorado.
 
Happy planting.
