I built this large raised cedar bed for a person who lives in a nearby town who wanted a place for veggies:

The bed is 8′ x 4′. The posts are 4×4 fir while the sides are tongue and groove cedar. (The choice of fir may have, in fact, been a mistake.) But the sides are dadoed into the posts, and that did turn out to be a good decision: after five years filled with dirt and plants shifting in the frost and thaw, the walls are still perfectly flat.

Here it is in the shop before finishing:

I finished it with a few coats of spar polyurethane, but that definitely didn’t hold up more than a year or two. Here it is only a year later, weathered completely gray:
