Regarding the logs as borders: All of my beds had log borders, but they are approaching a decade old and are starting to show their wear and tear. In two of my beds I actually broke up the remainder of the logs that were still left and dug them into the bed as a sort of hugel-light technique. My remaining beds likely have a few more years in them, but they too will decay away at some point. I don't want to go and chop down perfectly good hardwood trees to use them for garden beds so I was wondering what other options were available for 2x lumber. Everyone here has given me some great ideas.
Redhawk, I have heard of the borax-as-preservative before, but always in the context that it was water soluble and therefore transferred out of the wood (where you do want it) and into the soil (where you don't want it). Is there any truth to this? As a solution to this I have heard of people using the borax and then covering with either paint or tar like driveway sealant. I am interested on yours or anyone's thoughts on this.
Again, thanks in advance,

I find in most areas there is always stone or other materials available for free or low cost and you will know best yourself what you can get.
