Mature Spruce Trees


Anonymous added on May 14, 2017 | Answered

Hi! We are looking to dig a basement for our home close to 40+ ft (45 year old trees). We don't want to hurt the trees so were wondering how far away we should keep the excavation? The diameter of the trunk 4.5 ft up from the ground is 15". Thank you for your help!

Most Spruce Trees roots are more shallow and will extent beyond the size of the canopy.
