I'm in a wet/damp climate for much of the year though winter and snow may slow down my raised beds from rotting. I use 2x12 and replace as needed...each one only once in all these years. Almost 20 now.
I have read the new pressure treated is probably safe but still an un-known 'probably'. It isn't so much the leeching for me but how often i'm working on and around the wood...kneeling on, touching all the time. Then harvesting crops and salad greens. Double digging takes soil from the edge to the middle...and i don't spray and practice organic so makes sense to me to keep pressure treated to fence posts only.
