Q.Is Plastic Tarp Safe To Line The Sides Of A Raised Bed?
My husband built two raised beds last fall. He bought plastic tarp from a big box store and tacked it on the inside of the wood to help preserve it. They are filled. Now I am concerned that the plastic will leach toxins into the vegetables. I am in Wisconsin and it is not planting season yet. It would be a big project to get that tarp out now. Just wondering about the safety. I’m not sure what kind of plastic it is.
