I am in the process of replacing our raised garden beds. They are 18 beds on the right of the drawing.
They are over 7 years old and rotting well. We used standard 2x6s to build them along with compost and vermiculte and peat moss within.
Now since we have to replace them are we ok in using 'green' treated lumber if we want to stay as natural and chemical free as possible? We worry about the green chemical leeching into the soil and then the vegetables. The cost of green lumber is not much different than standard lumber, but a LOT less expensive than, say, cedar. The key is we'd prefer to have it last at least 12-15 years before needing replacement.

Any suggestions would be appreciated.

Hello JHrusky.
I would be concerned over the long term use of treated lumber too.
You could use a liner inside the raised beds to prevent contamination of the soil.
I'd do some research on which liner would be best for the long term.
 
Raised beds are such a game-changer for gardening, right? They keep everything organized and easier to manage. As for green safety, I think it really depends on the materials you use. Treated wood can sometimes have chemicals, so I'd go with untreated wood or even metal for a safer bet.

I actually found this cool guide on building metal raised garden beds ( https://www.mklibrary.com/how-to-build-metal-raised-garden-bed/ ). Super helpful and pretty easy to follow! Metal beds are durable and look kinda sleek too.
