What are folks using as the framework of their raised beds?
I'm trying some 2x10's rough hemlock pine.Be interesting on how long they
last in zone 5 Western Massachusetts.
Is the new copper treatment for pressure treated lumber any safer than the
old arsnic pressure treated lumber?

Thanks

I used aged pressure treated wood with an aluminum liner between the
wood and the soil. The sides are about 18" tall with 24" aluminum
roofing flashing nailed all the way around the inside of the frame.
Been using the same bed for about 20 years now and it's still in
pretty good shape.
