Norway spruce trees are a great choice, they're pretty fast-growing, especially when they're young. On average, they can grow around 3 to 5 feet per year for the first 10 to 15 years, which is pretty quick. After that, the growth rate slows down a bit, to around 1 to 2 feet per year. As for how long it takes for them to reach their full height, it can vary, but generally, it takes around 50 to 70 years for a Norway spruce to reach its mature height of around 50 to 80 feet. So, if you're looking for a tree that will provide shade and beauty to your yard relatively quickly, Norway spruce is a good option.
