I'm in the process of building several raised beds, some of which I'm building using pressure-treated southern yellow pine; but I'm also building some from untreated yellow pine. I've got a couple of concoctions I'm putting on the untreated wood, to see how long the wood will last; but, if any of you have run across any wood treatment that you'd like me to try, let me know and if I can I'll include it in the test. I'll be watching these beds over the next couple of years, and I'll keep y'all posted on the progress. Harry Harry Boswell hboswell@netdoor.com USDA Zone 8 http://www2.netdoor.com/~hboswell
