I have about ten 8ft by 4ft beds made from scaffolding boards, thing I would do is line them on the inside with some polyethene or something only on the inside, then clout nail or fix down with strips on outside. I find giving this extra bit of protection will increase the life of the boards big time, and if installed when building, is well worth the effort.
I have had scaffolding borders for about 3 years, I havent lined or treated them and I think they are just untreated. I paint them every year and they seem to still be in good condition. I read you should expect to get about 10 years from them before they need replacing.
When I built my raised bed 4 foot high I lined the bottom and sides as my local horticulturist said that
1.Bad reason....Lining it was bad as the tap roots could not go down as far as they would like ....parsnips go down 8 foot !!
2. Good reason....slugs hide in the corners of the bed between the lining and the boards...I put my lining along the bed and up the outside of the boards
Everyone is just trying to be Happy.....So lets help Them.
