The picture above shows the first piece of plastic going down. I dug a 6" trench around the perimeter to bury the edges of the plastic. Where the plastic came up to my sheet metal walkway, I just tucked it under the metal.
The picture above shows the first sheet of plastic mulch in place. It is 10' 6" wide and about 30' long.
I spaced the three plastic-covered sections apart 12". That Fiskars flat-blade shovel visible in the above picture is the tool I used to dig the perimeter trench for burying the plastic edges.
I've learned from previous experience with this woven plastic that if it is cut with a knife it frays. It has to be cut with heat so the edges melt. I used a propane torch to heat up a 3" diameter biscuit cutter to make the rows of planting holes. The plastic has lines on it, which help with keeping the rows of holes straight. I used little sticks of wood, as shown above, to help space the holes at 12" on center. Melting holes with a biscuit cutter and torch is tedious.
The rows of holes are spaced around 28" apart. I have five rows of holes per sheet of plastic.
I will keep you updated on how this idea works.
