Anyone know of a good wood that is not treated that can be used for a retaining wall? I dont need to get 1000years of out of it.
Right below will be a garden which is why I dont want any leaching from pre-treated lumber (arsnic or copper).
I am also willing to treat with a natural oil, and dont mind doing so every year or what ever it takes.
The wall will about 3 feet high-ish. Any wood knowledgeable people who can chime in, I would greatly appreciate!
Scientific studies have proven that any copper that may migrate from the treated wood becomes biologically inactive, thus causing no eco-toxic or other environmental impacts.
