How Fast Do Spruce Trees Grow?
Varieties Spruce refers to the Picea genus of plants, which includes 35 separate species. While the majority of these coniferous tree species have a fairly unremarkable average growth rate (between 6 inches and 11 inches per year), the Sitka spruce (Picea sitchensis), Norway spruce (Picea abies) and Colorado blue spruce (Picea pungens glauca) are renowned for their extraordinarily fast rates of growth. Top Growth Rates The Sitka spruce dwarfs its cousins in maximum attainable height and rate of growth. During its 500-year life, a Sitka spruce will reach between 160 and 220 feet, with 60-inches-per-year growth rate until it reaches maturity. Coming in second with an average growth rate of 30 inches annually, the Norway spruce has an impressive yet manageable height between 40 and 60 feet. With a branch spread of 25 feet across, landscape designers will often arrange Norway spruces to provide privacy and wind blockage for houses on larger lots.
