They are also effective specimen plants or can be used in mass plantings where space is available. Spruce grow native in the cool-humid northern regions of the country from New England through the Great Lakes to the West Coast. Most species of spruce are fairly stiff and formal. Their habit is a strong vertical line which can dominate home landscapes. Cultivars have been developed which fit small, intimate landscapes.
All spruce are sun-loving plants.
Shade or competition from other trees will cause thinning, decline, or death. They should not be used as an understory tree like our native hemlock. Spruce grows best in fertile, moist, yet well-drained soil. There are a few insect and disease pests associated with spruce. However I find that trees planted in the proper location that are given reasonable care are not as likely to be affected with pests.
