Overview of the Plant
Common Names, Vernacular Names
Picea glauca var. albertiana ‘Sanders Blue’ is known by several names, including White Spruce, Sander’s Blue Spruce, Skylands Spruce, and Albertiana (Glauca Group).
Its name is derived from the Latin word “picea,” which means “pitchy,” referring to the resinous sap that it produces.
Description of the Plant
White Spruce is a coniferous evergreen tree that grows up to 15-30 meters tall, with a trunk diameter of 0.5-1 meter. Its bark is thin, gray, and scaly, becoming reddish-brown with age.
The plant’s needles are short, stiff, and blue-gray, growing up to 1 centimeter in length, and are arranged in a spiral along the slender branches. Its cones are cylindrical, reddish-brown when ripe, and can grow up to 10 cm in length.
The cones disintegrate when mature, releasing their winged seeds. This tree is also capable of producing resinous sap to protect itself from wounds and damage.
The plant’s natural habitat is northern regions of North America, where it thrives in cool and moist environments. It is an important species in the boreal forest ecosystem, supporting wildlife with its habitat, including providing nesting sites and food for birds and small animals.
Moreover, the tree is used as a source of wood for paper and lumber, making it an important economic commodity.
Plant Cultivation and Care
Preferred Growing Conditions
White Spruce prefers growing in full sun to partial shade, in soil that is moist, well-drained, and slightly acidic to neutral. It is a hardy tree that can adapt to different soils, but it thrives best in loamy soils.
The tree is cold-tolerant and can withstand temperatures as low as -50C, making it an ideal plant for northern regions. It prefers a humid and cool climate, which is why it is commonly found near lakes, forests, and other water bodies.
Potential Pest and Disease Issues
White Spruce is relatively resistant to pests and diseases. However, it can be susceptible to certain insects and diseases, such as spruce budworm, spider mites, and rust.
To prevent pest infestation and diseases, it is essential to maintain good soil and tree health, including regular fertilization, pruning, and watering. Early detection, identification, and proper treatment of pest and disease problems can prevent long-term damage and minimize the extent of damage.
Planting and Maintenance Tips
White Spruce can be propagated through seeds or cuttings. Seeds should be sown in fall or early spring, and the plant should be allowed to grow without disturbance or stress for two years before transplanting.
Cuttings can be taken in early summer, and the rooting process takes several months, usually supported by greenhouse or mist propagation. To maintain the plant’s health, it is essential to provide the tree with adequate water, especially during the early years of growth, to establish deep roots.
Fertilizing the plant annually with a balanced chemical or organic fertilizer can help improve plant health and growth. Additionally, pruning can encourage new growth and remove dead, damaged, or diseased branches.
It is important to prune away branches only when the tree is dormant to avoid causing injury.
