Have you considered using a trench digger for burying cables? A trench
digger can make a trench about 3 inches wide and 12 to 18 inches deep quite
easily. Put whatever barrier you want in there and back fill.

What does one of these trenchers do when they encounter roots, Ron?
(kick up, cut through ???) thanks
