    though weed suppressant fabric lets water through...

    sounds like its been out in the wilds for a fair old time so I'd think that anything would have leached out -

    however - I'd like to point out that I'm not a bio-chemist with regard to either statement made in this post

    1574 gin and tonics please Monica, large ones.

    As Urban said above, it's maybe worth sticking some plastic on the inside of the wood anyway to help lengthen the life of the wood. I've used compost bags cut up and stapled them to the wood in the past.

    Thanks everyone for chipping in. It is indeed quite "aged" stuff so I think I'll be ok. I will look into pond liner/recycling existing plastic bags *like that later idea) to both stop the wood rotting and as a bonus is might stop any remaining stuff leaching in.

    Buiders Damp Proof is ideal for this and it will also help prevent the wood from rotting.

    Lining it should also help retain moisture as the wood won't be drawing moisture from the soil and losing it as the wood is warmed by the sun...

    same here, I used weed fabric to line my planters, everything inside seems to be happy. I think it might also help with allowing a small amount of air to flow and allowing even drainage.
