All the wood is Cedar. One of the biggest reasons I garden is so I don't have to eat chemicals on or in my food. So untreated cedar was the only way to go even though it's pricy! I don't think I'm even going to stain them because of the chemicals in that even though it would look pretty.
p.s. I drafted this post a while ago and forgot to post it. We are almost done with the fence now. Just a few things left to do. I'll be sharing pictures soon!
