Here I use TallEarth.com's ECO-Safe Wood Treatment to preserve and protect a raised standing bed garden box I built. I am happy with the product. It is environmentally friendly, non-toxic and easy to use. I had the promo code ECOCULTURE setup with TallEarth.com to get you a 10% discount!
I'm not sure if they are still honoring the promo code, I haven't heard from them in a few years, so maybe call and ask before purchase.
It is available on Amazon as well: http://amzn.to/2C4uvAr
I built this raised garden bed for the how-to article I wrote here: http://mikesbackyardnursery.com/2014/12/build-raised-garden-bed/
Keep above it all and stay hungry, my fellow Steemians!
