Q: I am considering using some 2x6 inch material for a small raised bed for strawberries. My first thought was to consider pressure treated lumber, but I have read conflicting articles on the the safety of this product, with the chemicals possibly reaching the plants. Others claim this doesn't happen and the lumber is safe. I would appreciate your opinion on this matter.
