Norway spruces are symmetrical, formal-looking trees with strong wood and dense, deep green foliage made up of short, square needles in drooping branchlets. Spruces are prized for their color and distinct form that holds up well even with age. Prefer moderately moist, well-drained soil but perform well in clay soils of the Midwest. They can be planted in most average soils in the area with enough moisture during establishment. Avoid pruning lower branches, they will help shade and cool the soil. Effective as windbreaks.Because of their moderate growth rate, Norway spruces form a dense habit that rarely needs pruning. If needed, prune just the new growth in the spring as it is forming.
