Quoting a job to have beds created with plastic edging, top soil, and mulch. Customer would like me to create bed about 36" away from house and run about 80 feet along the side of the house. I have already tried talking this customer out of the plastic edging, but they insist. Can anyone recommend the easiest way to tackle this job? I was going to start by measuring out 36" with some lawn paint and then cut it out with a stick edger, then manually get rid of it with a shovel, then install plastic edging. Any thoughts are greatly appreciated.
