It is a beautiful and adaptable tree that provides vertical appeal to different garden environments. It is a favorite option for homeowners and landscapers, has a thin design and requires little upkeep.

 

They grow to reach 30 feet tall and spread 10 feet. It has a low canopy and should not be planted underneath power lines. It grows quickly and, in perfect circumstances, has a 50-year or longer lifespan.

 

Plant this tree in full sun. It thrives in moderately to uniformly moist situations but cannot withstand standing water. Apparently they can withstand ambient salinity and is not sensitive to the pH or kind of soil, and may even flourish in inner city settings and has a high tolerance for pollutants from cities. This particular variant of the plant is not native to North America.

 

Appearance: 

Columnar Norway spruce is characterized by its tall, narrow shape, which resembles a column or spire. Usually reaching a height of 20-30 feet and spreading only 3 to 5 feet, it’s a great option for tight locations or as a vertical emphasis in the landscape.

 

Foliage of Columnar Norway spruce:

The tree has dark green needles that are short (about 0.5 inches long) and sharp-pointed. The needles are arranged densely along the branches, giving the tree a lush appearance.

 

Cone Production:

Like other Norway spruce varieties, they produces small, cylindrical cones that hang down from the branches. These cones are usually reddish-brown in color and add to the tree’s ornamental value.

 

Growth Rate:

Columnar Norway spruce has a slow to moderate growth rate, adding about 6 to 12 inches of height per year, making it easy to maintain in a small space, as it does not require frequent pruning to control its size.

How long does a columnar Norway spruce tree live?

 

These trees can live for 150–300 years. However, growth conditions, maintenance, and environmental factors can affect how long a plant lives. With proper care, columnar Norway spruce can live for several centuries, providing beauty and structure to the landscape for generations.

 

 

Can you propagate the columnar Norway spruce tree from seeds?

 

Yes, you can propagate columnar Norway spruce (Picea abies ‘Cupressina’) from seeds, but it’s important to note that the offspring may not necessarily inherit the columnar growth habit of the parent tree. Here’s how you can propagate columnar Norway spruce from seeds:

 

Seed Collection:

Collect mature cones from a healthy tree in the fall when the cones have turned brown but are still closed. Place the cones in a paper bag and allow them to dry for a few weeks until they open and release the seeds.

 

Seed Extraction:

Remove the seeds from the cones and separate them from any debris. The seeds are small and winged, similar to other spruce seeds.

 

Seed Treatment:

They have a stiff seed coat that can prevent germination. To increase germination rates, place the seeds in a plastic bag with damp sand or peat moss and store in the refrigerator for 1 – 2 months. This procedure replicates the cold, moist conditions the seeds may naturally encounter over the winter.

 

Planting Seeds:

Use seed trays or pots with a well-draining potting mix. Plant the stratified seeds about 1/4 inch- deep in the soil and gently cover them with a thin coating of dirt. After planting, give the dirt a good soak. Soak the soil thoroughly after planting.

 

Germination:

Put the seed trays or pots in a cool, shaded area or a refrigerator for the cold stratification period. After stratification, place the trays in a warm, sunny spot and maintain a constant moisture content but not soggyness in the soil.

 

Transplanting:

After stratification, place the trays in a warm, sunny spot and maintain a constant moisture content but not soggyness in the soil.

 

Care:

Provide adequate water and sunlight for the seedlings as they continue to grow. Protect them from extreme temperatures, pests, and diseases.

 

 

Common pests and diseases of the Columnar Norway spruce tree

 

It is susceptible to a few common pests and diseases, although it is generally considered a hardy and low-maintenance tree.

 

Here are some of the main pests and diseases to watch out for:

 

Pests:

 

Aphids: 

Aphids are little, squishy insects that consume tree sap. They may result in growth retardation, needle yellowing, and the formation of a sticky material known as honeydew.

Spider Mites: These microscopic arachnids cause the tree’s needles to turn yellow or bronze by feeding on them. A tree’s health may deteriorate, and foliage lost due to severe infestations.

 

Spruce Budworms: 

Spruce budworms are caterpillars that feed on the buds of the tree, turning them brown and dying. Severe infestations can lead to defoliation and branch dieback.

 

Spruce Gall Adelgids: 

Spruce gall adelgids are tiny insects that cause the formation of galls (abnormal growths) on the twigs of the tree. While galls are unsightly, they usually do not cause serious harm to the tree.

 

Diseases:

 

Needle Cast: 

A fungal disease that causes the tree’s needles to become brown and fall off too soon is called needle cast. It is most common in damp, humid conditions and can be prevented by enhancing air circulation around the tree.

 

Canker Diseases: 

Canker diseases result in sunken, dead patches on a tree’s bark and are brought on by different fungi and bacteria. If left untreated, cankers can girdle branches and finally destroy the tree.

 

Root Rot: 

Different soil-borne fungi can infect a tree’s roots, causing root degradation and a reduction in the health of the tree. Yellowing needles, slowed growth, and branch dieback are some of the symptoms.

 

Rust Diseases: 

Fungi that generate orange, rust-colored patches on tree needles are the cause of rust diseases. Rust infections can weaken a tree and increase its susceptibility to other pests and diseases, while they are usually not lethal.
