Another thing to think about is if opening a trench, do you want to put a barrier in there to minimize future root pruning needs. A few years back, we did a perimiter of a green, lined with galvanized roofing steel 2x thick, and the hope is this will block any future needs anymore. Once the suckers from the roots under the greens die that is.
