Paver base around that as back fill. Slacker here. Those only lasted 20 years or so before complete failure. Wet clay soil here.
It looks like https://coppercoat.com/coppercoat-leisure-antifoul-applications/ is also used in marine paint to prevent algae buildup. |
they'll probably do just fine. There are a lot of variables concerning how fast wood rots. The climate, termites, micro organisms, soil and drainage capabilities for sure but the wood species and quality are foremost. If the conditions are not good for your posts longevity then a 6x6 will rot out at the base as fast as a 4x4.
I wish i could get real deal copper green still but i live in CA. Gotta protect those salamanders ya know
