Blue spruces are genetically bred for a certain colour, habit, and growth pattern, and they are popular landscaping trees due to their striking pyramidal form, interesting texture, and year-round greenery. While some sources suggest that blue spruces should not be pruned at all, others recommend removing the candles on the very tips of the tree yearly to control growth. This is because blue spruces are genetically bred for a certain colour, habit, and growth pattern, and they do not usually have crowded, crossing, or heavy growth. However, if your blue spruce has been touched by someone clueless, selective pruning can help. When pruning, it is important to use the right tools, such as hand shears for small twigs, lopper shears for branches up to 1 1/2 inches in diameter, and pruning saws or chainsaws for bigger jobs. It is also important to prune at the right time, usually late winter or early spring when the tree is dormant, and to avoid wet conditions, which can invite disease.

What You'll Learn
Blue spruces should be left to their natural shape
Blue spruces are conifers with a conical crown when young, but as they age, they become more open and irregular in shape. The branches grow out horizontally in well-defined whorls, but the lower branches droop downwards. Blue spruces are genetically bred for a certain colour, habit, and growth pattern. They rarely have crowded, crossing, or heavy growth, so they do not need training or help. Blue spruces should be left to their natural shape and habit. Any attempt to shape it will ruin it.
Blue spruces are also susceptible to various pests and diseases. The spruce budworm, for example, eats the buds and growing shoots, while the spruce needle miner hollows out the needles, causing them to coalesce in a webbed mass. Mites can infest blue spruces, especially during dry summers, causing the oldest needles to turn yellow. To maintain the health of blue spruces, it is important to monitor them for signs of these pests and diseases and take appropriate action.
Blue spruces are native to the Central and Southern Rocky Mountains and moist mountain valleys and canyons to the west. They have also become naturalized outside of their native range, including in North America and Western and Northern European countries. Blue spruces grow best in full sun and require good soil drainage and proper watering during dry weather. They should be planted far enough apart to allow for good air circulation, as planting them in dense shade will cause needle drop.
Blue spruces are a popular choice for landscaping due to their striking pyramidal form, interesting texture, and year-round greenery. They can, however, become misshapen, overgrown, and susceptible to unpleasant conditions without occasional trimming. Proper trimming allows for more air circulation and sunlight penetration, encourages fuller growth, and helps remove diseased or damaged branches. While blue spruces should generally be left to their natural shape, light trimming can be done to maintain their health and visual appeal.
To maintain the natural shape of blue spruces, it is recommended to remove the candles, or new shoots, on the very tips of the trees yearly. This will help control growth without pruning, as once blue spruces are cut, the branches do not come back. When trimming, it is important to follow the general branching pattern and only remove dead, diseased, or broken branches. Proper identification and an understanding of growth habits are necessary to avoid destroying the natural shape and beauty of the tree.

Pinch off candles yearly to control growth
Blue spruces are genetically bred for a certain colour, habit, and growth pattern. They are popular choices for landscaping trees due to their striking pyramidal form, interesting texture, and year-round greenery. However, without occasional trimming, blue spruce trees can become misshapen, overgrown, and susceptible to disease.
To control the growth of your blue spruce, you can pinch off the candles, or new shoots, at the ends of the branches yearly. This will help hold back growth. When pinching off candles, aim to remove one-third to one-half of each candle by hand. Avoid pruning back into woody stems as new growth will not develop from these areas.
Pinching off candles is best done in early spring, before or just as buds begin to swell and new growth emerges. This allows the cuts to heal quickly as the tree directs its energy into developing shoots. It is also important to prune in dry conditions as wet conditions are an open invitation for disease. Additionally, mild temperatures ensure the tree isn't stressed by extreme cold or heat during trimming.
When pinching off candles, be mindful of the tree's natural conical shape. Identify and remove limbs that are dead, diseased, or disrupting the tree's shape. Each cut should enhance the tree's form, not detract from it.

Remove dead, diseased, or broken branches
Removing dead, diseased, or broken branches is an essential step in keeping your blue spruce tree healthy and beautiful. Here are some detailed instructions to help you with this process:
Firstly, it is important to properly identify the dead, diseased, or broken branches. Dead branches will typically have dry, brittle wood and may be discoloured. Diseased branches may show signs of infection, such as fungal growth, discolouration, or oozing resin. Broken branches may be partially or completely detached from the tree.
When removing dead, diseased, or broken branches from your blue spruce, use sharp and clean pruning tools to make precise cuts. Cut just outside the branch collar, which is the swollen joint where the branch attaches to the trunk. Ensure that you do not leave any stubs, as these can die back and affect the appearance of your tree. Always angle your cuts away from any remaining stem tissue to promote proper healing.
For larger branches, make thinning cuts that remove the branch back to its point of origin or attachment, such as a larger branch or the trunk. Avoid making flush cuts directly in line with the remaining stem, as this can damage the tree. When removing entire branches, it is crucial to respect the natural growth pattern of your blue spruce. Avoid pruning during the active growing season, as this can encourage new growth that is more susceptible to damage.
Additionally, be mindful of the size of your blue spruce. If it is over 10 feet tall, consider using pole saws or loppers to safely reach and prune upper branches. For smaller blue spruces, hand pruning or using a ladder may be more appropriate.
Finally, always clean and disinfect your pruning tools before making cuts to prevent the spread of diseases. Monitor your blue spruce throughout the growing season and be prepared to make additional corrective pruning cuts as needed. Remember that proper pruning will help maintain the natural shape of your blue spruce while also promoting its health and vigour.

Prune in late winter or early spring
Pruning your Blue Spruce requires precision and care. The timing of your pruning is crucial as it can impact the overall health of your tree. Late winter or early spring is the ideal time to prune your Blue Spruce, as the tree is still dormant, allowing for healing before new growth begins. Aim for a dry, mild day to avoid stressing the tree with extreme temperatures or weather conditions that can invite disease.
Before pruning, clean your tools with isopropyl alcohol to prevent the spread of disease. Safety gear is also important. Goggles and gloves are essential, and a hard hat is recommended if you're working under the canopy.
When it comes to identifying which branches to prune, look for dead, diseased, or disruptive limbs that are impacting the tree's natural conical shape. Each cut should enhance the tree's form, not detract from it.
In addition to removing problem branches, you can control the growth of your Blue Spruce by removing the candles, or new shoots, at the ends of branches. This will help hold back growth, but be aware that once you cut, the branches of this evergreen will not come back, so it's important to leave it to its natural shape.
As new growth appears in spring, you can prune back the tender current-season growth or "candles" by one-third to one-half when the needles are still tightly packed. Pinching by hand avoids damaging the needles and will promote fuller branching in the following year.

Clean and disinfect all pruning tools
Before you start pruning your Blue Spruce, it is important to clean and disinfect all your pruning tools. Clean your pruning shears with isopropyl alcohol to avoid spreading diseases. Wipe down the blades again before moving on to trim a different plant. Aim to prune in dry conditions as wet conditions are an open invitation for disease.
It is also important to clean and disinfect your tools after use to prevent turning your Blue Spruce into a petri dish for pathogens. Safety gear is also important when pruning. Before you make the cut, suit up with safety goggles and gloves. A hard hat is also recommended if you're working under the canopy.
Keep your tools razor-sharp as a dull blade mangles branches, inviting disease. Pole saws and loppers are also useful for safe, proper pruning of upper branches for Blue Spruces over 10 feet tall. Wipe down the pole saw between branches.
