Hi, I have a couple of fir trees in my yard. I believe they are balsam firs, but not sure. Anyways, I am planning on having a natural gas line installed underground, running from the street to my house. The method for installing involves using this torpedo-like technology which burrows its way underground to the house. These trees are in line with the the gas line path. If the roots are damaged by this torpedo, will the tree be able to survive? Thanks.
