If been into gardening for a while now and watched this group the last
few years... I have not used treated wood for reasons read here and
elsewhere. My only comment is I've also watched hundreds of
landscape/garden shows on HGTV and such and ALWAYS see treated lumber
in and around vegetable gardens - even rail ties quite a bit. I've
always liked the 'look' after a few years of weathering and now am
starting to rethink its use....
