I'm planning to build some large, deepish "boxes" for growing radishes, spring onions, lettuce etc. and would like to use "tannelised" (ie rotproof) timber. I've used this before for plot surrounds with no problem, but in this project the crops will be much closer to the wood, including on the bottom, near the roots. Will the stuff they soak the timber in stop growth or pollute the crops? If so, any suggestions for "lining" the boxes to protect the crops? Or other timber?
Many thanks, John N

Well JohnN

Can give you a partial answer..........I have lots of raised beds and boxes etc made from tannalised timber and everything has grown ok, even stuff that hangs over the edges. I am sure it is treated with something fairly beningn otherwise it wouldnt be used for houshold stuff like decking, planters and areas where kids and pets go. But don't take my word, as someone will have furthe facts I am sure.

This link helps a a bit I think

you could line the inside with plastic sheeting to stop the soil contacting the wood. i use a couple of old baths to grow carrots in.
