Can a bed lined with roofing shingles, (tar based), leach into the soil and contaminate my plants. one in particular - hibiscus saucer? It would cover 2' of the 2 1/2' wide and 2' of 6' long

On the other hand, many of us would have contaminated rain barrels if leaching were a serious problem.

That's an interesting question -- I have rain barrels and use the water on my veg garden, and have never thought about that issue (maybe because I don't garden strictly organically; however, I AM concerned about toxins and pollutants!).

There's an article from Rodale on this subject here: http://www.rodalesorganiclife....
