    How old is the wood?

    I 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.

    I don't think I would use those. Ask you local nursery what to do to minimize the chemical leaching that might occur.

    Just use cedar wood. That is what I have used and it works great!

    Prior 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.

    If you do not know how long the 8X8's have been lying around then I suggest you find some other lumber.

    NO - do not use treated lumber for a garden. Try cedar

    Yes you can, just make sure you line them with heavy landscape fabric.

    Thank 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!

    Thank You for all the input. I am going to build a tiered herb garden and then use containers for the plants. I have been thinking about this for a while. I will try to post a picture in a month or so when it is done. Thanks again! Happy gardening.

    If you think they may have some contaminant just sand down,seal,and also line with thick plastic!
