50 ft blue spruce tree

Asked August 6, 2020, 9:45 PM EDT

Is it safe to cut Blue spruce roots growing 15-20 ft from trunk 0-3” thick. My son and me planted this tree in 1981 so it is of

The answer to your question depends on how much of the roots do you plan to cut. It it's more than 25%, I would start to consider other options. When trees lose more than 25% of their root base (or one-quarter piece of the root area around the tree) they can suffer from loss of water and nutrients, resulting in the tree being stressed. Once a tree is stressed, it is susceptible to drought, insect and disease damage.
