Does anyone know how long one might expect *untreated*
lumber to last when in contact with the ground?

We're hoping to get raised beds constructed this year, and
I'm trying to compare the advantages of cement blocks vs.
lumber - we can buy either 'landscaping timbers' or regular
boards that are untreated. The 'landscaping timbers' are
about 8" x 8" x 8" - pretty thick - like a railroad tie, but
a bit smaller.
