Should the boards used to separate path from cultivated area in a modern
"raised bed" system be treated with anything or just left natural?

TIA

Have you considered using untreated wood but with a black plastic sheeting
material stapled inside to keep the soil from contacting the wood.....my
present ones have a lining of 7mm thick sheet black plastic..they are four
years old and without any rot...my previous ones at the last house lasted
16 years and would possibly still be in use had the new owner not changed
the design.....Harold W.
