Engelmann spruces are tall, narrow, spire-like trees with strong wood and dense, deep green foliage made up of short, square needle on ascending branches. Spruces are prized for their color and distinct form that holds up well even with age. Engelmann spruces has softer foliage than other species, with blue-green color. Bush’s Lace is a weeping variety. Best growth occurs in soils with good moisture. Avoid pruning lower branches, they will help shade and cool the soil. Because of their moderate growth rate, Spruces form a dense habit that rarely needs pruning. If needed, prune just the new growth in the spring as it is forming.
