I'm wondering if using plastic bags as a weed barrier buried under a raised bed for growing veggies is not such a good idea.
I know plastic tends to let out fumes over time. Underground I'm assuming this would be increased, but I don't know, would it decrease? Would the soil absorb some, most or all of the toxins? These toxins would end up in any of the plants grown so you probably don't want to eat them right?
If that's the case maybe I will use them to grow flowers but not food.
Is this worse for the environment(and how) than recycling the plastic bag?
