The carpet is movable as you change plantings from year to year. The best part is that it's free! Just stop by a job site and haul it home. All I'm doing is giving it a delay en route to the landfill. When I get it home, I just roll it out in the driveway, cut it into 16-24" wide strips with a utility knife, and re-roll the strips. This makes it easier to handle and store. I have rolled out a small room size carpet and planted my cantaloupes and squash through the carpet. No weeds and healthy rinds. It also gives you a defined outline to pull stray vines into. I usually opt for a beige or green, but if you use a dark color it will help warm the soil until the plants spread out.
