What to do in clay?

Hmm, I will check with my garden designer guy. I understood it was treated with salt.

Glad to hear Viv, and there ARE salt treated alternatives in use, but the majority of "treated" lumber out there is chromium arsenate or other heavy metal combos, really bad for edible applications... sounds like your garden designer is on it...
