White spruceCulture: The White spruce is very site adaptable but produces its best growth on moist, acidic, medium loams. It is tolerant of wind, heat, cold, drought, and prefers full sun, but is tolerant to some shade. The species is fibrous rooted and transplants readily. Susceptible to root and trunk rots, needle rusts, cankers, spruce budworm, European spruce sawfly, and red spiders. In forest situations, budworm and sawfly are serious pests. Usage: Useful as a specimen or in windbreaks. The variety densata, Black Hills spruce, is one of the most commonly available forms. Elias indicates that the tough and flexible young roots of this species were used by native Americans to sew their birch-bark canoes. |
