I would line them with some UV plastic, pondliner, roofing membrane, whatever you can get your hands on, to keep the damp soil from rotting the inside timber. I would then cap the join with a roofing batten so that you can mask the plastic and protect the exposed edge. Voila they will last as long as you weather proof the outside. I have 6 x 1 planked beds which have been made in this way which are over 8 years old and still as strong as an ox.
