Okay, now we've defined our rectangle. We're going to dig those whole area out and form a trench to throw our mulch into. We're going to take our shovel and dig into the soil loosening all these weeds and grass. Just dig those out, loosen them and when you have some excess soil, just load it here, into your container. I'm sure we've got some more excess soil. We're going to just load it into the container. Once the container is full, just take it and dump it into a corner of your yard. We're going to throw these excess weeds into our compost pile or into our green waste container. So, just go along, work your way along both rectangles and keep digging. So, we want this whole trench to be three inches deep. After we form the trench, we'll plant our Boxwood and then the mulch, the mulch will fill the entire rectangle. That's why we've carefully defined it so we can maintain nice, straight lines and create a nice, crisp edge.
