Dwarf spruce trees can be planted about 4 feet from the home, while larger spruce trees should be planted 14 to 20 feet from the home, depending on the species. The adult size of the tree can be used to determine where to plant the trees.
Tall, wide trees should be planted at least 20 feet from the home to ensure the root system develops properly. Trees that are under 50 feet tall when fully mature may be planted about 15 feet from the home, while smaller trees that are under 30 feet may be planted 10 feet from the home. Dwarf species, such as the dwarf Alberta spruce, can be planted as close as 3 feet from the home. Trees with compact branches and smaller root systems may be planted closer to the home.
