We'd like to build a small, raised veggie garden out of some left over fence board pieces that are treated wood. However, we planned to line the inside of the container with plastic since we are aware of chemical leeching into the soil from the treated wood. Does anyone know if this is acceptable safety measures? We were going to space the bottom boards 1/4" apart and cut slits in the plastic at these spaces for drainage. All four interior sides would be lined with plastic but the top edges (1/4-3/8" thick) would be exposed unless we were to roll the plastic over the top of the edges and top with trim made from non-toxic wood.
Does anyone think this is not safe? Other natural rot resistant woods are out of our price range and we were hoping to be able to recycle these treated fence boards for something.
Thanks!
