Now I’m 50 and can see death ahead, apparently I have to grow spinach. Or something. I’ve acquired a very large stack of scaffolding boards to create some raised beds. Should I treat the boards? I don’t mean buying them dinner and such. They’re bare timber as far as I can tell. So. They’ll likely rot. What does the hive mind suggest? For treatment. Not for my sunset years.

If you treat them you then have to line them.....just make the beds and accept that you will have to redo them sometime

As gz says, you could use a membrane of some kind or just replace as necessary

scaff plank is pre treated, usually with hardcore preservatives i use 1000gm/m visqueen as a liner, some use pond liner poke a few holes in the base of the liner for drainage but keep soil and timber separate

Even oak will rot, so just accept that you will have to replace them every so often. If you are only 50 you are a mere whippersnapper. Gardening is one of those things that you can do at any age; we started on our own account when we got our first house in our early 20s and have been gardening ever since.

These look like bare Timber. They’re BS2482 boards, which doesn’t specify treatment and I’d guess the manufacturer would shout about it if they were treated.

H&S Dpack will be pleased to know I stopped using the powered rip saw and jigsaw when I could no longer feel my fingers in the cold. I’m going for no treatment and a few years of life. If I decide to treat them it’ll cost more time now and I’ll find something more exciting to do. Like watch the treatment dry.

I lined mine with pond liner and then treated the outside of the boards with creosote. Then I topped the boards with creosote treated pallet wood.
