White spruce trees can live for more than 1,000 years in protected environments. They grow into a dense, pyramidal tree 40 to 60 feet tall and 10 to 20 feet wide. These trees are hardy in USDA Zones 2 to 6, which means they enjoy the cooler regions of the north. This is why they grow best in Canada and Alaska. Knowledge of how to plant this tree can help you produce a sturdy and healthy, long-living tree. Obtain a young white spruce seedling from a reputable nursery. Alternatively, start seed from the white spruce indoors and make sure it is ready in early spring when the danger of frost passes.
Find an area where the tree will thrive. White spruces prefer full sun in moist, well-drained soil. It will also do well in partial shade and in dry soil. This tree will grow in clays, sands and loams, as long as they are well-drained.
Dig a hole twice the size of the seedling root ball and as deep as the root ball. Stand the tree upright in the center of the hole.
Backfill half the soil into the hole and pour water into the hole. This will settle the soil around the roots and eliminate air pockets. Backfill the rest of the soil into the hole and water again.
