Don't rotivate! I personally wouldn't use carpet but plastic is readily available if you don't want to use weedkiller. Carpet often contains lots of chemicals which apparently leach into the soil but if you're not planting edibles I dare say it's fine.
Sorry Fairy but I am sure there are far less chemicals in a synthetic carpet than there is in glyphosate. Its the cocktail of ingredients needed to make the glyphosate stick to the weeds that is awful affecting humans as well as wildlife.
David stick to the carpet/plastic idea. Do not use poison on a large area please.
