Raised bed lining

I’ve built a raised bed which is a retaining wall as well, i was talking to a friend who said I should line the inside of the sleepers, just looking for advice, picture below.

I was initially thinking of putting gravel between the soil and the sleeper so it just drains but now I’m not so sure, I don’t want it rotting in a few years

All cuts have then been treated

Thanks I’ll get some ordered, had I realised I would have fitted it as I built it!

There is a gap between the soil and the timber at the moment so if I were to drop it down the gap I could fix the top and the bottom would have to be held with the soil
I was advised against this when I did mine. As any water that would get down between the liner and the sleeper would not be able to escape and would not be able to breathe. So would always be damp. I was going to do it on all mine then decided against it.

I was intrigued by that liner - it's permeable - I'd probably use something like that when making another raised bed. They can dry out rather too fast otherwise.
