So one of the projects we're hoping to complete this summer is making a fence for our garden area. I'm totally against using treated wood at all, although my husband thinks I'm a bit wacky for refusing to let him use it even for the posts (and for not letting him use Roundup to kill the grass that's where the garden's going to be!!!).
He found someone on Craig's list who's selling hedge posts (osage orange) from some land he cleared. Apparently these make fantastic posts, and take forever (many decades) to rot. So does everyone think it's a good idea to use osage orange wood near where we're going to grow vegetables, and around chickens?
I've heard the fruit is toxic, but we'd just be using the cut trunks.
On a similar note, we're thinking of using a living fence, like wisteria, instead of planks to fill in the fence itself. We'd put support between the posts, and then grow the wisteria close enough that deer, dogs, and chickens couldn't get through. The raccoons could still climb it, though. Any thoughts on that?
