Last year, I had 20 tomato plants, each about 4 feet high. 19 of them disappeared. The silver lining of our COVID19 economic downturn is that I got furloughed for a week. I'm very blessed. Many people are suffering right now. Most folks are at least bummed that they have a week off and nowhere to go. Not me! I will never run out of projects. This week, I chose to dig up my garden and lay down 1/2" wire mesh, stitched together like a shallow box with no lid, then put the garden back down on top of it.
I dug right down to the level of our water main, 1-inch copper. To protect the pipe, I split 1-inch PVC in half and covered the copper before laying down the galvanized steel mesh. My favorite tool for cutting PVC is the band saw. To keep the cut straight and prevent the tube from twisting too much as I cut the 10-foot piece lengthwise, I made a riving knife out of scrap slotted steel angle.
I cut the wire mesh with aviation shears and folded the sides up and folded a 3-inch flange out around the top. At the corners, I stitched the sides together.
