We are mid reno's at our place at the moment. We had to dig a trench to put our electricity underground. The trench was needed to run right through the middle of my Tomatoes. So I carefully dug a trench 600mm deep, being ever so careful not to damage my tomato babies. Thankfully I managed. I now have an electricity box right in the middle of this part of the garden. I think I will need to find a perennial to grow there so I dont need to dig around here. Little bit scary.
