Tamworths are great diggers and particularly like digging around their fence boundary, be it stock, posts, electric or anything else. So they would probably make a deep groove/ditch along the hedge side as well and expose/eat a lot of the hedge roots, this might be a problem with a narrow plot along a 100 m length. And when the monsoon rains return, as I am sure they will, this ditch will turn into a long wet gooey canal with torn roots sticking out above the water and mud. On the other hand, if you have free draining soil, and some sort of slope somewhere, unlike our place, things might not get this bad! Tamsaddle
