Wendell,

Arsenic, copper, and chromium called chromated copper arsenate (CCA) have all been used as wood treatments. Human exposure to this stuff is well documented as being bad for you. As a framing contractor for many years this was a constant worry to us. And the poor kids who play on outdoor structures built out of it. yuck!

Of course the lumber industry maintains that it is safe, of course. As to plants Conmmon sense would tell you not to plant an edible item in it. But as to trees, well CCA is basically a pesticide and most trees are pretty hardy toward sprays and dust, etc.

The EPA has a ton of stuff you can't do with treated wood like burn it, compost shavings, use it for animal bedding, or in building and storage for animal or human food storage, and on and on.

So one has to ask oneself is it worth it. Ya know, to your own health let alone to your precious potensai.
