Patti, I love watching your videos and envy those great raised beds! I have three 4x4 ft beds I've put in over the last 2 summers and plan to add more this summer (I have to move slowly b/c dh is one of those "big grassy lawn" kinda guys). Anyway, I avoid anything pressure-treated but can't afford composite wood or cedar, etc. that is naturally rot resistant. What, if anything, have you coated your wood with to protect them from the elements? I had some back in my old garden, in Georgia, and after 18 months they were half-eaten by termites! Luckily we don't have much of that problem here in Maryland, but I'd still like my beds to last through the rain and snow (currently several feet on the ground).
editing to bump this up and see if anyone else has an answer?
