What trees are ok to plant near septic lines so the roots do not interfere with the septic lines? Any suggestions on what to plant near septic lines, staying 10' away from the lines?

As a general rule tree roots will extend up to 2. 5 times the height of the tree, and some species of trees may have roots extending five to seven times the height of the tree. With that in mind you may want to keep any trees within 10-15 feet from any sewer lines. Of course, even those less prone to damaging these lines will seek out water if not given enough--just another thing to keep in mind. Possible choices here include some varieties of lilac, crepe mytle, and dogwood.
