Along the same lines as the OP mentions, was wondering about utility poles
for an above ground garden border. They've been exposed to the elements for
at least 15 years. Not greasy, but dusty surface. Creosote, I believe.
Intend to wrap them with heavy plastic with excess draped length to the
inside of the garden.

Hi,

I'm building a couple of wooden planters from scrap lumber. The
lumber is pressure treated, but that's all I know about it. I will be
growing vegetables in the planters, so I am wondering what I should do
to treat the lumber. Should I do anything to the interior surfaces?
I'm guessing that stain or paint is not a good idea if I'm going to
eat the vegetables grown in the planter.

Thanks for the advice.
