Product Description

Sleek Silvery Hues on a Timeless Evergreen  

With silvery blue-green tones year-round, a sleek pyramidal silhouette and straight-forward, no-nonsense care, the Colorado Blue Spruce Tree ticks all the boxes of a landscape must-have. Streamlined by its columnar shape and stiff, crisp needles, it’s poised to impress, no matter where it’s planted, from season to season.

And when it comes to planting and care, the Colorado couldn’t be easier to maintain. This well-known beauty withstands wind better than most spruces because it boasts a widespread, deeper root system. Plus, it’s long-lived (seriously…it can last hundreds of years!) and provides food and shelter for graceful wildlife, like siskins, crossbills and nuthatches.

Even better? It adapts well to a variety of soils, from acidic to clay, and requires normal moisture with moderate tolerance to drought. Also, with a manageable growth rate of 12 to 24 inches per year, it’s easy to acclimate to your landscape with its uniform growth and symmetrical branching.

Basically, the Colorado Blue Spruce Tree is a one-of-a-kind cultivar – not just your typical evergreen – especially since its needles are 95% blue. Whether you’re looking for an all-natural privacy screen or windbreak, these Spruces are ideal for planting in a row and are the best selection for container growing.

A festive twist in the form of light brown, 3 to 4-inch cones concentrated in the upper crown sets the Blue Spruce apart, making it a delightful backyard beauty during the holidays and beyond.

Fresh foliage and full growth, free of hassle. Is there anything better than a no-nonsense evergreen with the added perk of vibrant, unique beauty? Order a Colorado Blue Spruce Tree of your own today!

Blue Spruce

I had a great experience buying from Fast Growing Thus far, the trees seem to be doing great and have shown new growth. One of the trees looked great and the other was a bit straggly upon arrival. I also purchased a Sugar Maple and it is doing wonderful and growing as well. Now I wait for the prices to come down on a couple of other trees and I will buy from Fast Growing Trees again.

Slow growing

Received it last year was disappointed with the color which was nowhere near blue. It now (a year later) seems to be turning a bit towards blue depending on the light. But is overall very slow growing.

Seems happy where I planted it.

I'm very pleased with my Colorado Blue Spruce. It has taken off just as predicted on your web site now that the weather has become more Spring-like. The soil tends to be very moist where I planted it in my yard so I hope it will establish well there.

Planting & Care

Discovered in 1862, this spectacular species’ origin is rooted in enchanted meadows and side streams, high in the Rocky Mountains. Once found, the Colorado Blue Spruce’s popularity skyrocketed. Today, it’s one of the most planted cultivars by professional landscapers.

And true to its name, it’s the state tree of Colorado and is heralded for its unique beauty not only in the Rockies but also across the country. Best of all, it’s super easy to plant, nurture and maintain, though proper care prepares the Spruce for a long, lush life.


First, it’s important to locate an area with direct sunlight for your Colorado Blue Spruce. Though it thrives in full sun, it will also grow in partial shade. Furthermore, a wide range of soil types supports the Blue Spruce, clay, loam or sandy, but ideal soil will be a loose or sandy loam.

And although it’s highly drought, wind, salt and pollutant tolerant and withstands periods of water shortage better than many other spruces, its preference is moist but well-drained soil with an ideal pH between 6.0 and 7.5.

Once you’ve found your ideal area for planting, dig a hole that is shallower than the root ball and at least twice the width. If you’re planting several Blue Spruces together for privacy fencing, ensure you space them at least 10 to 20 feet apart.

After your hole(s) are ready, loosen their soil so that your Spruces’ roots can easily break through. Separate the roots of your Spruce gently and position them downward in the hole – note that the top of the root flare, where the roots end and the trunk begins, should be approximately an inch above the surrounding soil.

Ensure that the plant is placed exactly vertically in the hole, back fill with dirt, and apply water to remove any air pockets. Remove debris, such as stones and grass, and break up any errant dirt clumps.


Again, Colorado Blue Spruces are a strong, durable cultivar but are healthiest with proper watering.

To encourage proper growth, water your newly-planted Blue Spruce Trees at least once a week during the first year after planting, until the ground freezes during the winter. More frequent watering may be necessary during the warm summer months to keep the ground adequately moist.

If you’re not sure when to water, simply feel the soil near your tree, down to about a depth of 1 inch. If it feels dry, it’s time to water. At that point, you should soak the soil around the roots thoroughly but avoid overwatering, as too much moisture can lead to root rot.

To help the soil retain moisture even more efficiently, spread 3 to 4 inches of mulch around the base of the Spruce. Mulching also aids in suppressing weeds and maintaining proper temperature.


Although Colorado Blue Spruces don’t require frequent fertilization, an application during early spring (before the growing season) provides an extra boost of nutrients for longer needles and richer color.

To fertilizer your tree, start by measuring the length of the tree to its outer canopy edge and extend that length beyond the edge of the canopy, or dripline. This area is called the root zone.

Then, measure the diameter of the Spruce from one side of its canopy to the other, and multiply this number by itself – for example, if the diameter is 10 feet, you should multiply 10 x 10 – to determine the square footage. You should use one pound of 10-10-10 slow-release fertilizer for every 100 square feet.

Sprinkle the granulated fertilizer over the soil inside the root zone, using a fertilizer spreader or jar with a hole-punched lid to ensure even dispersion. Following this process, water the soil with about 2 inches of water to incorporate the fertilizer further and prevent burn.

Pests and Diseases

Your Colorado Blue Spruce is relatively resistant to pests and disease, though certain insects and a few diseases can do some damage. Keep a mindful eye for the following:

- Spider mites are the most serious pest affecting the overall health of the Colorado Blue Spruce. If your tree's needles turn yellow, you should examine for these tree mites on the branches. If your tree is still small at this stage, you can hose off the mites with a strong spray. With larger infestations, use an insecticidal soap or a chemical insecticide and follow the package instructions.


- Gall-forming insects produce small bumps or growths that may look like miniature cones at branches’ tips but will not harm your Spruce.


Other than canker problems in Eastern areas, serious damage is not inflicted by most diseases. Canker causes needles to brown before they drop and produces white patches on infected branches. Treat the disease by removing infected branches and avoiding overhead watering to keep foliage dry. Also, sterilize your pruners after use to avoid spreading the disease. Minor Spruce diseases also include needle cast and rust that turn needles yellow or brown and cause them to drop, but these aren’t serious either.
