Where do spruce trees grow in the world?

Spruce trees primarily grow in the northern hemisphere, thriving in temperate and boreal forests. They are commonly found in regions such as Canada, Alaska, Scandinavia, and parts of Russia. Additionally, spruce trees can also be found in mountainous areas and higher elevations where the climate is cooler. Their adaptability allows them to flourish in a variety of soil types, though they prefer well-drained, acidic soils.
