We just bought a house and the sewage/water line runs through a small black locust stand. It empties into the leach bed on the other side and adjacent to the bl stand. I forgot when it was installed, but it was in the last ten years. The trees next to the pipe are damaged due to cut roots.
I plan on cutting down one or two of the bl trees. I am aware that cutting down a bl invigorates new growth and a bunch of root suckers pop up. I plan on allowing the new growth as it is a very useful tree.
My question is this: will the root suckers send shoots into my sewage pipe and cause blockage?
You may want to try the Paradise tree trick, and cut off the bark in a ring around the tree, without cutting the cambium. That cambium cutting starts the suckering in Paradise trees.
copper keeps roots out, without killing trees. it is the "blue" stuff in the pipe cleaning additives. don't know if copper phosphate, or other copper salt tho.
