Irene on Jul 13, 2016I have heard that treated 8x8's are not good for plants. They can leach chemicals that are toxic to plants. It might be worth finding that out from a greenhouse or plant nursery....or google it.Helpful Reply

Jean Moore on Jul 13, 2016I don't think I would use those. Ask you local nursery what to do to minimize the chemical leaching that might occur.Helpful Reply

William on Jul 13, 2016Prior to 2003, pressure treated wood used a copper chromium arsenic compound and was harmful in every way. Decks, raised beds etc, would leach/transfer the chemical to plants and people. After 2003 pressure treated wood has a copper chromium ammonium compound. The ammonium compound makes transfer and absorption of the chemical almost impossible. You can use newer treated wood for raised beds without any problem and little concern.Helpful Reply

Bob Graham on Jul 14, 2016Thank You to all for your input. The timbers are not too old and I think I will use them to build a tiered herb garden off my deck and then use containers within the frame in which to plant. Thanks again!Helpful Reply
