- Life cycle
The common name of Picea glauca var. albertiana 'Alberta Globe' is Dwarf Alberta Spruce. Its life cycle begins with germination from seeds, which typically requires a period of stratification to break dormancy. After sprouting, the seedling gradually matures into a juvenile plant, exhibiting a dense, globe-shaped form of finely textured needles. As it enters the adult phase, the Dwarf Alberta Spruce continues to grow slowly, maintaining its compact, spherical shape while developing a woody trunk and branches. Reproductive maturity is reached in several years, and the plant starts producing cones containing seeds to continue the species' cycle. The Dwarf Alberta Spruce can live for numerous decades, with its shape gradually becoming more pronounced as it ages, and ultimately, it will senesce and die, completing its life cycle.
- Propogation
Propogation time
Early Spring
White Spruce 'Alberta Globe' is commonly propagated by cuttings to ensure that the genetic traits of this dwarf cultivar remain true to form. The best time for taking cuttings is in the late spring to early summer when new growth is semi-hardwood. Cuttings should be about 4 to 6 inches long, with the lower needles removed to expose the stem. These prepared stems are then dipped in a rooting hormone and placed in a well-draining potting mix. They require a consistently moist environment with high humidity, which can be maintained by covering the cuttings with a plastic dome or using a mist system. It can take several weeks to a few months for cuttings to root effectively. Once roots have established, the young plants can be transferred to individual pots and gradually acclimated to outdoor conditions before being planted in their final location.
